I also got a kick out of that..... I've had my Haas for about a month now and I still tense up a bit when I press that Green start button hoping I didn't mess up on the settings!
Hi, I know its 4 years old but still... I tried to go over all the comments but didn't see anybody mention this: I don't know how important this is but in the "Recommended" method of Adaptive+Contour+horizontal - if the contour does not touch the floor and the forizontal does not touch the wall - wont it leave an un finished ring at the bottom of the hole?
Try turning on setting 103 when running through a part for the first time. Hold the cycle start button to run, let go and it does a feed hold. Great control for walking the tool down to check the Z height.
2:40 You addressed my EXACT concern as I watched my bit ram into the side of my work. This is the definitive help channel for Fusion 360 and DIY machining!
When programing tool motion, when you have tool path that would generate a small I or J number (in g-code) your part surface feed changes. Your feed rate is the center of the tool as you go around a corner one side of the tool has a lower surface velocity, while the other side has more. We use GIBBS System and it has constant surface feed. It varies the IPM feed line by line if need. Saves tool life and makes a more uniform wall surface finish.
Just a few tip that might help you: 1: Press "current command" and page up until you get the menu where you can see the current position of machine and the distance to go in according to work offset and the G-code in the program - this is a great help when running the program first time to avoid crashes. I have a 2 year old VF4 - with older control so it might be different on yours. 2: Coolant - just press coolant button - it turns off external cooling straight away. (you probably knew all this already) 3: Air coolant: I think its just to choose "MIST" in fusion tool library and you will have air coolant instead of flood. Im quite sure i tested it already. 4: Preload of tool: Thats just to change in the post processor setup window in Fusion - choose "preload tool" to yes and it will preload all tools - its exclenet function - saving a lot of time. I adore all your videos - they are great help and played a big part in my way to make my own rifle! Thanks - I´ll be more than happy to help you with some HAAS tips if I can.
I guess most NC programmers aren't old unix hands, but: sed 's/M08/M73/;s/M09/M74/' does the job good and quick, to replace your flood coolant with air coolant (I had to look up the M codes for Haas). You can accomplish the same thing in more time opening the NC file in wordpad/emacs/gcode editor/etc, and doing replace-all M08 -> M73, replace-all M09 -> M74, save. I'm sure there is a way to do that automatically in Fusion 360, but I find it just as easy to postprocess NC using a bunch of sed or perl scripts that end with sending the fixed up NC to the machine ready to run.
I am trying to figure out how to do a 3 tool pocket leaving a radiused corner about the bottom with the ball mill as finish. Is that 3 pocket routines, or can I put 3 tools into the pocket like with the old software? Thanks! Mark
John, what is the plugin that allows you to toggle to wire frame? You should check out Swift Calcs. Probably the best plugin for saving energy and accruacy
Love the video john. If you shoot this again, use pockets that aren't round. The fact that the pockets are round made a lot of the toolpath similar. Also, would love to see you test the tapered helical entry. As always, GREAT VIDEO! Love seeing the Haas in action.
Hi,Is there any Blog or website to guide the beginner of CNC operators online? For example; I show them my drawing and they help me how to make it by CNC machine???
Any chance of a secondary coolant system like a mist or air-blast which could be used for CAM testing (and videography), perhaps at a lower feed rate, before unleashing the flood coolant system?
I'd like to know too. My gut tells me there's a reason every single high spindle speed machining center I've ever seen operates under large volumes of flood, usually from several simultaneous angles.
I'm finally getting around to learning CAD/CAM, and your channel is by far the best learning tool around. For your adaptive/contour/horizontal tool path, is there any reason that you can't skip the contour step, and use the horizontal to clean up the side walls too?
Gage Pin Test? I would be interesting to see which method produces the most accurate hole size. Also compare Haas versus Tormarch. Its possible that different methods on different machines have better accuracies.
A call of help Mr.Saunders. I want to have a part made from a cnc machinist i know. I have the part modelled, but he usually asks for the file in IGES format. Now i want my part to be made within a tolerance and needs to achieve a specific fit. I talked to him and he says not much can be done. Can you please explain to me how you manufacture your parts for obtaining desired fits?
When face milling, make sure the entire cutter feeds across the face. Otherwise you get that funny looking finish like you have on the left side of the part. Not that it mattered here. Just future reference.
Yeah, but I like to extend the tool past the edges for the whole part, not just at the end. You can accomplish it with stock contours as well, lots of ways to skin a cat. :)
Again a Great Video! One question: how do you handle tolerances like H7? Say 0 up to +0.02mm. Is this possible without changing the the construction-model?
The profilometers i've used would all have a difficult time measuring anything there. You could measure along the bore, but since it's not transverse to the tool advance/scallops it won't produce an accurate reading anyway. Measuring for diameter and roundness is the way to go, and a true CMM is the way to do it.
Yes, which is about a nothing in this video. 99.99 % of parts probably do not need to have an exact deadsharp corner, so the issue is very very specific application.
If you're unsure about your z-height a great tip is to use your "handle feed" - instead of going back and forth between feed hold and cycle start. Run it at a 100% rapid with this, the rapid will slow with the feed percentage. Also G92 is your friend if you want to use a permanent 0-point. G54 is always the top left corner of my vice, then use G92 to move your zero to whatever matches your part. (instead of probing everytime.) You might also be surprised with how much the rigididty of the machine and the flood helps. You can take some really aggressive cuts in aluminium as long as the chips can evacuate. (e.g. 80%stepover, full depth with a 1" tool ~8000rpms, 140in/min)
Hey John, Long while back (1995) I had Issues with my wiper motor in my car. It was an old beater and I did not want to spend cash on replacement motor, but I need to see in rain storms. Found a product at the local Auto parts store called "RainX". It is a water disperser that I now put on all my cars and RV's. With this stuff on the glass, I rarely ever need my wipers as this stuff is so good. I suggest you try and put it onto your equipment shields. In combination will a light air stream. I'm sure coolant obstruction between camera and work piece will be much reduced. :)
John, I love your new machine, but remember, a lot of us are Tormach owners (hobbyists, makers, prototypers) who look to you for innovation and experiment with your PCNC1100. Don't forget us. There are lots of other excellent resources for professionals, but there are very few for us.
I can't recall exactly what it is off the top of my head, but there's an entry clearance parameter on the 2D pocket tool that allows you to manually center the helical entry and then spiral out from there. And I think smoothing tries to output arcs instead of line segments. It's been a while :P
Great to see the Haas action! Looks like you are brushing up on making good holes for my little fit test. :-) No fair cutting feeds though unless you run it twice to show that both can do the job just one is faster. :-)
Knowing that the HAAS controller works its own magic on any code uploaded to it, I am curious if the tool path follows Fusions' Gcode exactly and if there are any acceleration curves that differ from posted output.
I use Powermill and Lemoine, tolerance in programming is everything. You can really mess up if tolerance is bigger than stock left, stepover, stepdown. Its good to have big tolerance for roughing so it creates less points and then thats less code so machine moves fast. Haas may be better nowadays for that. You'll know when you try 3d with it
Awesome to see the Haas making chips John. I have found on my Tormach the facets show up much more on an exterior cut using adaptive rather than a pocket.
I'm just wondering.... why do you start your downward spiral so far above the part? it makes 3 to 4 revolutions around the set diameter before it comes in contact with the material. I know it's not a huge deal with the type of work you do but in a production manufacturing environment it seems like it would save time not having it cut air for that duration of the cycle? love your channel long time follower thanks keep it coming I look forward to seeing your videos every week. congrats on the new HAAS purchase I would be equally as excited lol
It's not so much him as it is the Fusion defaults. I has a VERY high default start for helical ramps. You grow old waiting for it but it's there for a good reason. You can change the default helical ramp height easily and set it a lot closer, but you have to do it each time you make a new setup. I'm pretty green at this, but in my experience in a one-off job you are better off wasting 10 seconds waiting on a helical ramp to contact than finding out you weren't quite right on your stock height and crashing the tool into it before it starts the helical ramp. I go back and set my start points really close... after I prove out the part and stock. If you are doing one part and you need to hold your finger on the feed hold button you have to have the helical ramp start early enough that you have time to see it working with a slow feed before crashing into the part. Otherwise if you do your CAM setup full speed efficient right off the bat you get a FAST rapid straight down into position a few thou over the stock and a near instant contact on the helical ramp. It's scary as all heck on a cycle you havn't actually tested. Bad, bad crash if you don't KNOW it works.
I use a 4th axis trunnion. Its a task to make it turn the shortest way - so I needs to manually edit the code - A code - to make sure I dont have collisions with the table. The AD post team told me its possible to change some setting in the Post Processor code to make it turn other way/shortest way - but didn't try it yet. I have the rotary engine on the right hand side in the machine.
On the face mil op, you might want to change your lead in/out rates to the same as your cutting rate, plus use the "Extend to retract" option. HSM does this funky thing where it changes to lead in/out in the middle of the cut. It's annoying, but you can fix it every time you throw a facing op on there.
You can set the default on a checkbox in HSM Works? I've tried and haven't found a way, but you know... I can be clueless! Just tried to use the kinda hidden "Changes" menu to set Yes as default on Extend Before Retract, and it didn't work. Seems like it's possible that way, but not-working.
The adaptive does leave facets on the side walls. I've seen it on some of my parts that I didn't clean up with a contour. Love your videos. Keep up the good work!
Great job getting it up and running. Now that you can change tools, I mean your machine can change tools, chamfer everything you can with the machine, I lowers your variance part to part. Ruff and finish with separate tools, If THE HAAS has thru the spindle coolant (let's hope so) the DIN AD+B Flange Coolant endmill hoders work wonders. Making a washer tool, 1" stock 7/8 drill almost thru one end, 5/32" holes from the other end wash the chips away while your operator stays clean.
I have a profilometer, but it really needs big areas to operate well. The bottom of a hole would be really hard. If you made that floor 1/16" deep or less with 1" or more diameter, our profilometer would work.
Glad to see you got your HAAS running. Man! that probe is SWEET!!!!!!! I love mine. I am sure in time you will be experimenting with adding custom probing operations to aid in the setup of your parts on the machine. Look forward to seeing some of them in action on your channel. Being able to adjust both the Feed Rate and the Rapid Rate on the fly is another great feature. Being able to use the feed hold and turn off the coolant is a great option for looking at the part during the machining operations. You can also add a custom code to the end of your machining cycle to center the part at the door opening and bring the table all the way forward for ease of removing your parts. Not sure if Fusion 360 supports this or not but there might be a way around it by cutting and pasting code either in the Fusion 360 post processing or at the HAAS Control. One other thing that you might??? want to look into is an air blast nozzle. I made my own but HAAS does offer one. Have Fun! John
Haha, sure it is. If you have to play with spindle and feed overrides all the time your not doing something right. I have a robodrill that has the knobs, I use them one time per part maybe. I also run a Haas and do the same. While I prefer my the robodrill on the whole, the Haas control is much more user friendly and faster to operate in almost all regards.
Must have just turned Friday in NYC barely haha you're early John. Glad you're having fun with the haas, I like the clean look of the control panel and haas just seem to have thought of everything around the machine.
Except for the fact that the normal G-Code (as pretty much all cnc's use) does only start selecting the right tool (rotating the magazin) after the previous tool has done it's job. With todays complexity and capability of controllers or in general PCs one could expect a kind of "look ahead" feature that knows which tool to use next and therefore prepares the next tool while the current one does it's thing.
Haas does use look ahead. Different work offsets block it though, so its best to pre-set the next tool just using T* on a separate line of code, immediately after your previous tool has been grabbed. That way, the tool is ready and waiting for an instant tool change :-) I think haas done a video on it once.
David Dean ok, didnt know that, im not that much into the specifics of cnc machines. would an immediate repositioning of the tool delay the other machine movements though ?
No, its basically just giving the machine a heads up, telling it to get that tool ready for the next round of cutting. So once the code is executed (takes about 1/10 second) the SMTC moves while the next lines are executed.
I've almost done version with customization and ability to save preferences in cloud(as new project in fusion called '_Preferences') or on local as a simple file on disk. In couple days live version should appear on appstore but for now you can test it from here github.com/pawelzwronek/fusion360-VisualStyles/tree/feature/customization Any comments and suggestion please leave as an issue on github or here forums.autodesk.com/t5/api-and-scripts/my-first-add-in-visual-styles/m-p/6725197 or email me. Have a nice day.
Thanks for share I just install Fusion360 last week and your videos has been very helpfull I like the Bore method for roughing I used to use 2D Helix in Mastercam for Roughing and 2D contour for finish Thanks, hope you keep doing videos and tutorials!
that flood coolant.... now I remember why I don't watch Hass videos on TH-cam lol... I prefer dry milling to flood coolant, when ever I put water on my end mill, my end mill snaps.
The best way to get a nice round hole out of a Haas is to use a G12/G13 for your circular pocket. I'm switching everything over to Fusion 360 and am looking forward to not having to MDI that kind of stuff.
dont get me wrong i like the fusion 360 part but the hass was pretty much coolant on glass from this end lol the part looked good thought. keep them coming john. :)
well you got that right we was a little antsy to see the awesome factor of the new Hass lmao just a small reminder john people dont go to NASCAR to see car;s go around in a circle. so showing some mistakes on a new machine makes you human and let us relate better to the long term plan of your success. have a nice holiday season .
that would make an awesome candle holder if the holes and the candles where the same size lol... maybe round off the corners and give it a nice chamfer... would be pretty cool
not gonna lie, you could get yourself a better mic to reduce the background noise, i know its a workshop and can be like that but a better high quality mic can make a huge difference
Hey John I have both a cmm ogp and a device to check surface finish if you would like to send it to me I'll make a video of the inspection and kick it back to you!!!!
Hi John, First of all, Congrats for the new HAAS, you deserve the success :) Great CAM tutorial Please stop using the HAAS as if it is a tormach :) , push the feed rate to the limit.... I think that's whay you did not see any difference in the final surface finish, because of your conservative feed rate (I fully understand that it is a new machine to you and you prefer to go slowly). I see you get a new vise, an "Orange", can you review it a bit? Good luck
CMM will tell you next to nothing for that. Im sure all those holes are well within tolerances. (one thing the CMM is not very good @... small ID holes) The CMM will not gauge finish either. One more thing those eye holes in your head are good for
3 separate operations to rough, finish wall and finish floor? Autodesk really should update their software, SolidCAM has had this for years and with iMachining it will save your cutters and time.
Crap, they sent you a geneva SMTC? The whole point of a SMTC is to be fast! I thought they only offered the servo option for the SMTC? You better double check your order and make sure they didn't mistakenly install the wrong SMTC.
Geneva drive is great because its simple, just a motor, gear/cam assembly, and a limit switch. My machine has the same design for the tool changer turret. However the down side is there slow because it stops at each location. Servo drive is faster but more money and complexity.
I disagree, I had a Haas with geneva and a Tree with servo. The servo couldn't be simpler, it was just a servo motor, 2 gears for reduction, and a home switch. It was FAST and had fewer parts than the Haas, and being of the same age and usage, was in FAR better condition.
RIchard Fitzwell VM's don't rapid that fast. 700ipm Thats it. They have closer pitched ballscrews since the machine is designed for accuracy not speed. Where as the VF's have 1,000ipm rapids. That's also why there's a $30k difference between and VF3 and a VM3.
Kinda jelly for this machine tbh. But then again, I run two 9 axis and one 8 axis lathe at the same time (terms and conditions apply where available) if need be because pro cnc machinist :D
Haha I love the way you stand at the Haas, hand on the cycle stop button. I've spent countless of hours hanging my hand on the red one :D
I also got a kick out of that..... I've had my Haas for about a month now and I still tense up a bit when I press that Green start button hoping I didn't mess up on the settings!
Hi, I know its 4 years old but still... I tried to go over all the comments but didn't see anybody mention this: I don't know how important this is but in the "Recommended" method of Adaptive+Contour+horizontal - if the contour does not touch the floor and the forizontal does not touch the wall - wont it leave an un finished ring at the bottom of the hole?
I was thinking the same thing. I prefer using adaptive then pocket with no stock to leave to finish both the floor and the contour.
Try turning on setting 103 when running through a part for the first time. Hold the cycle start button to run, let go and it does a feed hold. Great control for walking the tool down to check the Z height.
Heard about the setting 103 awhile ago... Works slick
2:40 You addressed my EXACT concern as I watched my bit ram into the side of my work. This is the definitive help channel for Fusion 360 and DIY machining!
I'm actually physically excited for you and your new machine. Will be great.

Thats just to change in the post processor setup window in Fusion - choose "preload tool" to yes and it will preload all tools - its exclenet function - saving a lot of time.
I adore all your videos - they are great help and played a big part in my way to make my own rifle! Thanks - I´ll be more than happy to help you with some HAAS tips if I can.
I would like to see you run that on the 1100 to show how it differs on the smaller machine in overall finish per hole.
Awesome!
I guess most NC programmers aren't old unix hands, but: sed 's/M08/M73/;s/M09/M74/' does the job good and quick, to replace your flood coolant with air coolant (I had to look up the M codes for Haas). You can accomplish the same thing in more time opening the NC file in wordpad/emacs/gcode editor/etc, and doing replace-all M08 -> M73, replace-all M09 -> M74, save.
I'm sure there is a way to do that automatically in Fusion 360, but I find it just as easy to postprocess NC using a bunch of sed or perl scripts that end with sending the fixed up NC to the machine ready to run.
How has the learning curve for learning the Haas control been?
I am trying to figure out how to do a 3 tool pocket leaving a radiused corner about the bottom with the ball mill as finish.
Is that 3 pocket routines, or can I put 3 tools into the pocket like with the old software?
Thanks!
Mark
Doesn't the adaptive, contour and horizontal method leave 2 tenths stock on floor and sidewall?
by defualt yes, but you can turn that off
I can help out with the CMM report and surface finish readings as well. Just let me know.
John, what is the plugin that allows you to toggle to wire frame? You should check out Swift Calcs. Probably the best plugin for saving energy and accruacy
gus bisbal expand John's comments at the top of this and all will be clear👍🙈
apps.autodesk.com/FUSION/en/Detail/Index?id=170904292335894747&appLang=en&os=Win64&autostart=true
saw it downloaded it thank you.
Would something like Rain-X contaminate the coolant too much? If not, you could coat the inside of your filming window.
How do you know at what angle the helical path should go into the hole?
Love the video john. If you shoot this again, use pockets that aren't round. The fact that the pockets are round made a lot of the toolpath similar. Also, would love to see you test the tapered helical entry. As always, GREAT VIDEO! Love seeing the Haas in action.

I'm finally getting around to learning CAD/CAM, and your channel is by far the best learning tool around.
For your adaptive/contour/horizontal tool path, is there any reason that you can't skip the contour step, and use the horizontal to clean up the side walls too?
Does anyone know how to add cutter comp to the 2D adaptive? I'm trying to use regrind endmills.
I admire you Saunders!! Keep the awesome work you are doing!
Greatings from Mexico!!!
Gage Pin Test? I would be interesting to see which method produces the most accurate hole size. Also compare Haas versus Tormarch. Its possible that different methods on different machines have better accuracies.
I would love to see the different results Haas v. Tormach on this test!
Have you thought about using a pressure washer to clean out your fixture bed?
A call of help Mr.Saunders. I want to have a part made from a cnc machinist i know. I have the part modelled, but he usually asks for the file in IGES format. Now i want my part to be made within a tolerance and needs to achieve a specific fit. I talked to him and he says not much can be done.

When face milling, make sure the entire cutter feeds across the face. Otherwise you get that funny looking finish like you have on the left side of the part.
Not that it mattered here. Just future reference.
It really ruins the top appearance on an otherwise nice finish.
Yeah I wish that was the default for fusion, you have to always add pass extension, which I always do cause it annoys me to see that too.
Are you adding with pass extension? You can get the same deal with "Extend Before Retract." Way easier!
Yeah, but I like to extend the tool past the edges for the whole part, not just at the end. You can accomplish it with stock contours as well, lots of ways to skin a cat. :)
you are clearly a genius as I never saw that complex feature!!
How is that plugin for the wireframe called?
Wireframe View Plugin: bit.ly/2gphjue

Measuring for diameter and roundness is the way to go, and a true CMM is the way to do it.
If you don't touch the floor and then also don't touch the side you will leave an un-milled region around the entire bottom.
Yes, which is about a nothing in this video. 99.99 % of parts probably do not need to have an exact deadsharp corner, so the issue is very very specific application.
hey John, have you seen the Air Stik window blowoff system? might be a way of maintaining visibility with flood coolant on
I really love this series. Are you going to have a video about the final install of the Haas?
NYC CNC nice. you deserve all the success you've had. Thanks for introducing fusion to me. Life changing
If you're unsure about your z-height a great tip is to use your "handle feed" - instead of going back and forth between feed hold and cycle start. Run it at a 100% rapid with this, the rapid will slow with the feed percentage.

You might also be surprised with how much the rigididty of the machine and the flood helps. You can take some really aggressive cuts in aluminium as long as the chips can evacuate. (e.g. 80%stepover, full depth with a 1" tool ~8000rpms, 140in/min)
I thought you were getting the spinning glass window to film thru??? Next time show us a still so we can get a good look at the finishes. Thanks John.
How funny John, Running a HAAS while wearing a TORMACH shirt.....Awesome to see it up and running!
Hey John, Long while back (1995) I had Issues with my wiper motor in my car. It was an old beater and I did not want to spend cash on replacement motor, but I need to see in rain storms. Found a product at the local Auto parts store called "RainX". It is a water disperser that I now put on all my cars and RV's.

I suggest you try and put it onto your equipment shields. In combination will a light air stream. I'm sure coolant obstruction between camera and work piece will be much reduced.
:)
maybe weird idea... can you write code so that the flood cooling performs a t-slot cleanup ?
John, I could probably help out with measuring the surface finish if you want. Just let me know.
John, I love your new machine, but remember, a lot of us are Tormach owners (hobbyists, makers, prototypers) who look to you for innovation and experiment with your PCNC1100. Don't forget us. There are lots of other excellent resources for professionals, but there are very few for us.

Amy I the only one who finds it ironic that he's wearing a Tormach shirt when operating a Haas?
John, I hope this Haas thing does not interfere with whatever "arrangement" you with Tormach.
john you can measure the part on your machine using your probe. id be happy to measure it on my cmm if you want to send it my way.
Great to see the Haas action! Looks like you are brushing up on making good holes for my little fit test. :-) No fair cutting feeds though unless you run it twice to show that both can do the job just one is faster. :-)
My 2D bore always leaves a little material making the hole too small. Any idea why?
Knowing that the HAAS controller works its own magic on any code uploaded to it, I am curious if the tool path follows Fusions' Gcode exactly and if there are any acceleration curves that differ from posted output.
I use Powermill and Lemoine, tolerance in programming is everything. You can really mess up if tolerance is bigger than stock left, stepover, stepdown.

If you are doing one part and you need to hold your finger on the feed hold button you have to have the helical ramp start early enough that you have time to see it working with a slow feed before crashing into the part.
Otherwise if you do your CAM setup full speed efficient right off the bat you get a FAST rapid straight down into position a few thou over the stock and a near instant contact on the helical ramp. It's scary as all heck on a cycle you havn't actually tested. Bad, bad crash if you don't KNOW it works.
Great to see a cool comparative code like this. Will we see a walk around for the machine and overview???
Does the original Fusion post work with you trunnion? Or you haven't had a chance to test it out yet?
bojibka yeah the generic post will work with the trunnion, it just needs some stuff turning on inside it.
NYC CNC it will probably be one that supports DWO & TCPC
I use a 4th axis trunnion. Its a task to make it turn the shortest way - so I needs to manually edit the code - A code - to make sure I dont have collisions with the table. The AD post team told me its possible to change some setting in the Post Processor code to make it turn other way/shortest way - but didn't try it yet. I have the rotary engine on the right hand side in the machine.
Where do you find the plug in ?
On the face mil op, you might want to change your lead in/out rates to the same as your cutting rate, plus use the "Extend to retract" option. HSM does this funky thing where it changes to lead in/out in the middle of the cut. It's annoying, but you can fix it every time you throw a facing op on there.
Greg Koenig why don't you set the default?
You can set the default on a checkbox in HSM Works? I've tried and haven't found a way, but you know... I can be clueless!
Just tried to use the kinda hidden "Changes" menu to set Yes as default on Extend Before Retract, and it didn't work. Seems like it's possible that way, but not-working.
Greg Koenig do you mean the compare and edit dialog?
Scott Moyse It looks like Compare and Edit, but if you access it from a right click in the feature manager, it's called "Changes" (IIRC)
The adaptive does leave facets on the side walls. I've seen it on some of my parts that I didn't clean up with a contour. Love your videos. Keep up the good work!
Nice video! Personally, I prefer to finish the floor before the contour to have less vibration during the final contour.
you may want to think (and ask) about using wax on inner part of glass doors, coolant should flow right off, you will see much better as would we
loved the demonstration of the Hass
Great job getting it up and running. Now that you can change tools, I mean your machine can change tools, chamfer everything you can with the machine, I lowers your variance part to part. Ruff and finish with separate tools, If THE HAAS has thru the spindle coolant (let's hope so) the DIN AD+B Flange Coolant endmill hoders work wonders. Making a washer tool, 1" stock 7/8 drill almost thru one end, 5/32" holes from the other end wash the chips away while your operator stays clean.
Didn't see the blue hose go on the door when you slowed the feed rate down!
I have a profilometer, but it really needs big areas to operate well. The bottom of a hole would be really hard. If you made that floor 1/16" deep or less with 1" or more diameter, our profilometer would work.
Great video! I would highly suggest you make a removable cover for that table probe, doesn't take much to knock them out of calibration.
Glad to see you got your HAAS running. Man! that probe is SWEET!!!!!!! I love mine.
I am sure in time you will be experimenting with adding custom probing operations to aid in the setup of your parts on the machine. Look forward to seeing some of them in action on your channel.
Being able to adjust both the Feed Rate and the Rapid Rate on the fly is another great feature.
Being able to use the feed hold and turn off the coolant is a great option for looking at the part during the machining operations.
You can also add a custom code to the end of your machining cycle to center the part at the door opening and bring the table all the way forward for ease of removing your parts. Not sure if Fusion 360 supports this or not but there might be a way around it by cutting and pasting code either in the Fusion 360 post processing or at the HAAS Control.
One other thing that you might??? want to look into is an air blast nozzle. I made my own but HAAS does offer one.
Have Fun!
John
how to input the programme in machine
no feed and spindle speed override knobs? i would not work on that machine :/
There are buttons for that...
bensbenz not an alternative
Haha, sure it is. If you have to play with spindle and feed overrides all the time your not doing something right. I have a robodrill that has the knobs, I use them one time per part maybe. I also run a Haas and do the same. While I prefer my the robodrill on the whole, the Haas control is much more user friendly and faster to operate in almost all regards.
John Saunders I have access to a CMM if you want to send that piece.
Must have just turned Friday in NYC barely haha you're early John. Glad you're having fun with the haas, I like the clean look of the control panel and haas just seem to have thought of everything around the machine.
Except for the fact that the normal G-Code (as pretty much all cnc's use) does only start selecting the right tool (rotating the magazin) after the previous tool has done it's job. With todays complexity and capability of controllers or in general PCs one could expect a kind of "look ahead" feature that knows which tool to use next and therefore prepares the next tool while the current one does it's thing.
Haas does use look ahead. Different work offsets block it though, so its best to pre-set the next tool just using T* on a separate line of code, immediately after your previous tool has been grabbed. That way, the tool is ready and waiting for an instant tool change :-)
I think haas done a video on it once.
That has been possible for at least 20 years :-)
David Dean ok, didnt know that, im not that much into the specifics of cnc machines. would an immediate repositioning of the tool delay the other machine movements though ?
No, its basically just giving the machine a heads up, telling it to get that tool ready for the next round of cutting. So once the code is executed (takes about 1/10 second) the SMTC moves while the next lines are executed.
You're such a wonderful person and I adore what you do. Mr. John, can you or do you please have a video on how to print a drawing from fusion 360?
A master must also be a master of the basics.
How are you liking the Visual Styles addon, the guy who did it wants some feed back he's think of changing it.
the Hass is very quite and orsome
I've almost done version with customization and ability to save preferences in cloud(as new project in fusion called '_Preferences') or on local as a simple file on disk. In couple days live version should appear on appstore but for now you can test it from here github.com/pawelzwronek/fusion360-VisualStyles/tree/feature/customization
Any comments and suggestion please leave as an issue on github or here forums.autodesk.com/t5/api-and-scripts/my-first-add-in-visual-styles/m-p/6725197 or email me. Have a nice day.
Thanks for share
I just install Fusion360 last week and your videos has been very helpfull
I like the Bore method for roughing
I used to use 2D Helix in Mastercam for Roughing and 2D contour for finish
Thanks, hope you keep doing videos and tutorials!
Congrats with your new HASS CNC.
Please use your HASS shirt when you use your HASS CNC. ;-)
Looking forward to many new projects with this machine.
that flood coolant.... now I remember why I don't watch Hass videos on TH-cam lol... I prefer dry milling to flood coolant, when ever I put water on my end mill, my end mill snaps.
Single block and 5% rapid is your bestfriend.Love the channel and love the new machine. I learned on a vf2 then we got a brother! Scary fast machine
I wish i could see the milling process in machine.Can you use airblast next time for demonstration insted of flood cooliant?
I have access to a CMM and a Romer arm to give 2 different probing strategies
Great video, thank you very much 💪
As long as you have AAG HAAS has pretty good MQL option. It is good to see you up and running with it.
The best way to get a nice round hole out of a Haas is to use a G12/G13 for your circular pocket. I'm switching everything over to Fusion 360 and am looking forward to not having to MDI that kind of stuff.
dont get me wrong i like the fusion 360 part but the hass was pretty much coolant on glass from this end lol the part looked good thought. keep them coming john. :)
well you got that right we was a little antsy to see the awesome factor of the new Hass lmao just a small reminder john people dont go to NASCAR to see car;s go around in a circle. so showing some mistakes on a new machine makes you human and let us relate better to the long term plan of your success. have a nice holiday season .
Dude...love this video.
that would make an awesome candle holder if the holes and the candles where the same size lol... maybe round off the corners and give it a nice chamfer... would be pretty cool
not gonna lie, you could get yourself a better mic to reduce the background noise, i know its a workshop and can be like that but a better high quality mic can make a huge difference
Very cool John, congrats! (I'm so jealous... lol)
Hey John I have both a cmm ogp and a device to check surface finish if you would like to send it to me I'll make a video of the inspection and kick it back to you!!!!
Right when needed. Thank you
Awwww!!! now you made me want a machine I can't afford!!
Did you remember the feeling of your hart pounding and the raised blood pressure from the first times you run your smaller CNC? :P
15,000 rpm ftw! fswizard recommends some crazy RPMs for 1/4 inch and under AlTin carbide endmills, if you unlimit your max rpm!
Bore. That was the operation I was looking for. Works perfectly with not-so-rigid small routers when machining aluminum.
Hi John, First of all, Congrats for the new HAAS, you deserve the success :)
Great CAM tutorial
Please stop using the HAAS as if it is a tormach :) , push the feed rate to the limit.... I think that's whay you did not see any difference in the final surface finish, because of your conservative feed rate (I fully understand that it is a new machine to you and you prefer to go slowly).
I see you get a new vise, an "Orange", can you review it a bit?
Good luck
CMM will tell you next to nothing for that. Im sure all those holes are well within tolerances. (one thing the CMM is not very good @... small ID holes) The CMM will not gauge finish either. One more thing those eye holes in your head are good for
3 separate operations to rough, finish wall and finish floor? Autodesk really should update their software, SolidCAM has had this for years and with iMachining it will save your cutters and time.
Crap, they sent you a geneva SMTC? The whole point of a SMTC is to be fast! I thought they only offered the servo option for the SMTC? You better double check your order and make sure they didn't mistakenly install the wrong SMTC.
Was wondering if someone else picked up on that, but with a dual arm and buckets he should be able to prefetch the next tool.
Geneva drive is great because its simple, just a motor, gear/cam assembly, and a limit switch. My machine has the same design for the tool changer turret. However the down side is there slow because it stops at each location. Servo drive is faster but more money and complexity.
I disagree, I had a Haas with geneva and a Tree with servo. The servo couldn't be simpler, it was just a servo motor, 2 gears for reduction, and a home switch. It was FAST and had fewer parts than the Haas, and being of the same age and usage, was in FAR better condition.
one more trick, mount a gopro to the head looking down. for the most part, it stay out of the way of coolant.
Distance to go is your best friend when sneaking up in a part.
Ive tried to talk my boss into trying MQL, still trying!
Hello, Good job, Thank you
if you got the money, you should better get a blum laser tooling system. It is wayy better, we get precision up to a micrometer!
Nice work, John...looking forward to a lot more from you guys.
Now rapid the $hit outta that thing. ;-)
RIchard Fitzwell
VM's don't rapid that fast. 700ipm Thats it. They have closer pitched ballscrews since the machine is designed for accuracy not speed. Where as the VF's have 1,000ipm rapids.
That's also why there's a $30k difference between and VF3 and a VM3.
That's fair enough...but 700 ipm still supersonic compared to the PCNC 1100.
Kinda jelly for this machine tbh. But then again, I run two 9 axis and one 8 axis lathe at the same time (terms and conditions apply where available) if need be because pro cnc machinist :D
