Hi Jon. Great video and part. Just scheduled to share it today on all of our social media channels (Facebook, Twitter, Google+, Linkedin, and Pinterest). Thanks for posting it!
The tools in the carousel are set relative to the probe. The probe has a tool length offset of zero, and all the other tools have either positive or negative offsets depending on their relative length.
Top top operation removes material from the perimeter of the piece. When it's flipped and re-clamped in the jaws the Y zero location moves off by around five thousandths. If I had to spit out 10,000 of these things I'd consider programming the change in, but this is simple enough to do. If I used the finishing contour to rough the grips the cutter would spend half the time cutting air, unless you're considering doing it in one pass, which this machine would struggle to do. Thanks for watching!
Hi John, the other video is already up, I had a link to it in an annotation. I've now also added a link to the updated video in the description of this video. Enjoy!
we have three probe (renishaw) equipped haas milling centers at work. Handy as hell! We use them to qc parts before removing them from the fixture in case they need small dimension corrections.
I'm in a CNC class in my school, and we have recently been donated a Haas machine, i completely loved it and i just wanted to know how to get into Haas as a machinist. P.S. our coolant looks blue lol
Hi Leix99. It i supposed to be threaded, I'm waiting on a bigger threadmill in the mail to do the 10tpi thread though. There are also matching weld-on bungs that will have the matching thread. Once I get all of the parts together I'll make another video of the cap and the bung being made including threading. Thanks for watching!
Hi Jonathan Proce. Can you help me. I am running cnc hass v9 milling machine However, I do not know how to use automated metrics like the videos you share Would you please help me how can I use Auto Metering? If so please give me the program code. sincerely thanks Look forward to the help.
A few tips. You are already running limited engagement tool paths. So do all of the endmill work with a 3 flute mill for Aluminium. Limited engagement tool paths should not need a rough cut endmill. If a standard endmill is screaming or chattering. That means the speed, feed, and/or engagement needs adjusting. Put a nozzle with a small stream on your coolant line. That will increase coolant pressure to blast away the chips.
+shayson1357 I have used a 1/2 inch 5 flute carbide endmill on aluminium and 360 brass. Granted it was only buzzing material to length. But it worked very well. I do know 5 flute endmills do not like high radial engagements though.
It's best to avoid blowing chips around when the machine is changing tools. Chips are prone to get between the tool holder and the spindle taper. That causes tool runout (not good) and if the chips weren't soft aluminum could be hard on the tool holder and spindle. You can enable setting 42 on a Haas to automatically pause after a tool change so you can inspect or blow parts off, then resume by pressing cycle start. It's similar to M01 but you don't have to have M01 in the program.
Makes sence. We all need a little more HP in our machines. It IS a nice looking part btw and hell'ya...think of the things you could do on the machine needed to make 10,000 pieces.
we have a TM-1 in our shop with a 4k rpm spindle, although we were able to tweak the parameters to get 6k out of it, it sacrificed the torque a little, but ours doesnt have the flexible slide cover in the back, we call ours "Ms Piggy", because it makes a huge mess. (especially when flycutting) it throws coolant everywhere. lol
Haas page took me here, really nice part! I guess, as it's a cap, that needs some sort of threading? Or is that the finished part? Very lovely part, cheers :)
Why do you probe the part each time? It appears that you cut the form jaws which implies that you would already have the x-y-z fixture offsets. The 1st side doesn't matter so much but by re-probing the 2nd side, especially raw billet, you are losing your concentricity between the 2 sides. No biggy on a part such as this but bad practice for parts that matter. Also wondering why you would rough each notch instead of using the same "finishing path" for roughing? Just curious. Anodize and engrave?
I noticed you are using a Shars vise? Why not upgrade to a USA made vise. We make the Winn Speed Lock Vise which has an integrated Quick Change jaw system. Check out our video on You Tube.
Every one is having their say which is spot on in my opinion and my thoughts are that haas machines are very cheap and very fragile when they are required to cut metal that is a lot harder and stickier then ally in My Opinion every haas machine I have ever worked on or come across has struggled really bad or simply just not able to cut the material so to me this is evidence my original opinion was correct how did I come to this opinion ? I have spent 20 years cnc machining 5 off those years spent as a programmer operator on the shop floor the last 15 I worked I have worked on the apps for various machine tool builders which include both Mazak and what used to be Maho to name 2 From my own experience and I know other people that have purchased machines from haas and they quite simply could not do the job that the sales team said they could. Looking back with hindsight which I know is a marvellous thing they wish they had paid the extra money and purchased a better machine some of them actually did some got Hurco some got Mori some got Mazak yes the original outlay was a lot more but the machines run fine....,,, the Hurco runs 24/7 and has done for 5 month so it is what it is 😀
+Chris Murray In My experience with Haas Machines.. they are quite accurate.. i used to produce hydraulic parts on them.. like valve bodies.. the Haas did the job nicely.. the only bad point about it.. i just HATED the CNC Control.. i Prefer Heidenhain over anything.. or maybe Siemens.. they seem to be almost the same.. As a matter of fact.. i wrote my own CNC programming software, and developped my own language to have the same programming power on my own machines at home.. :)
Part of the OD was machined during the first operation, which means that when the part was flipped the part center shifted in the Y direction that amount.
30 year veteran Mechanical Engineeer/CNC Programmer/set-up/extreme editing Machinist here. For those who watch this... who want to learn the proper way to cut this part... use your jaw work-coordinate for both operations! It's already been established when you cut them! LOL! This is common sense if you are an experienced CNC Machinst! Concentricity will be almost perfect! Probing like this to set your work-coordinates is the wrong way to learn. Maybe hes just showing that you can probe with this app,,, but there is no text explaining why he is doing this. I'm not dogging your vid... just want others to know that this is not a proper way to set your work-coordinates!
duggy freshness After probing on the first side it would be simple enough to move the origin up half the same amount as was removed from the circumference during the first operation, but the stock OD has a tolerance of its own. The only way to ensure concentricity after the flip is to probe it again, unless the actual stock OD is measured each time and the compensation is adjusted. It's probably not worth much thought since it took less time to probe it than it did for you and I to write these comments.
Material is removed from the OD of the piece during the first operation. This changes the position of G54. The part must be probed again to update G54 to the true center.
Its not, it seems like an amber color, also its only 6000 rpm is that what you have. 1570 hr spindle run time. its a clean machine. ps: i'v been running a tormach 770 so this will be a substantial upgrade x5..
jon, is there an area to allow you to see the machine run time. Now i know theres a place but i was told the motherboard battrey removed resets this but there is a master that cant be. Does this sound rite? thanks for all your thoughts, I was told from a macherny place 1570 spindle hr cant be rite..
+vergil albia That's my main complaint about the TM-1. The coolant tank is way too small. It runs out before the coolant can get back to the tank. Keep meaning to make a bigger one for mine.
Jon Proce i can see why the machines wore out, you are part of the too fast too hard club. slow the fucking machine down! all those hard stops and starts are hell on the machine.
We make brake calipers, two halves, with four pistons, no probing, including fluid passages and tapping for bleeders, it all lines up and takes less time than per pair! Also with softer accel's and decel's.You guys. wtf. Making up for wasted motion by rapids that are too fast and too far.
I don't think you needed to probe it twice. The part is already centered with the first position. You're also probing on rough stock anyways. Not the best accuracy. Also, why in the fuck are you blowin' air around while it's doing a tool change?? Probably getting chips in the taper.
Jon Proce you thank haas for making good machines what planet are you on are you sponsored by haas ? Haas are the cheapest most fragile machines out their if you think that What kind of machining have you been doing thanks for the giggle you have just gave me and the boys in the apps department quality by the way and I don't mean Haas machines.
This machine is 12 years old, has had little to no service, and was purchased for less than 10% the cost of most of the machines you're referring to. Even so, is performs fast enough for its application and holds tolerances to the original spec. HAAS makes excellent machines.
Jon Proce Nothing wrong with buying wore out machine for giggles, thats for sure. If this is a business, you are doing it all wrong. If this is your garage, then you are doing it all right ;)
Diesel Ramcharger didn't say he bought it used. Holds original tolerance spec = not worn out. Of course he could replace it with a newer Haas like your company has done, but why n the hell but a new machine to take the workload off this TM when it's doing the job? That would just be a waste of money.
What exactly make them the cheapest most fragile machines out there? The great price points aren't because of cheap parts, they are from buying great parts with enormous quantity. Give Rexroth or nsk a call and say your from Haas looking to build a new line of machines and see how fast they want to come show you their newest stuff. After their done cleaning up their pants anyway.
Iceberg86300 Dudes a fucking idiot. We make shit tons of money with Haas machines, after ten + years we sold them all for nearly what we had in them and bought all new machines that make the parts even faster! Woot! Fan boy internet idiots. They are everywhere. I bet he blames the machine when he crashes them too. We had one of those guys. Fired his ass.
In reading your comments this is now pathetic. If you're making a high toleranced part. There is no need to use the probe every time. You should know where your part is when you flip it over. Ie. Adjust your offset accordingly and make the part faster. It's a Fucking gas cap. Even nascar isn't going to probe that shit! An overuse of unnecessary tools if you ask me.
Painfully slow !! 10,000 rpm at least, carbide cutters... 100 IPM ..... Rock the shit out of it... 3 minutes per side max. Thread mill on second side, part complete.
Thanks for your feedback and for making such great machines!
I love working on all of our Haas CNC lathes and mills.

Feels so slow compared to the VF-2, I also agree with probing, doesnt hurt if you are not in a hurry,

Put a nozzle with a small stream on your coolant line. That will increase coolant pressure to blast away the chips.
Or a good 4 flute with deep flutes works well on aluminium as well. With limited engagement, a 5 flute may work well also.
a 5 flute ??
+shayson1357 I have used a 1/2 inch 5 flute carbide endmill on aluminium and 360 brass. Granted it was only buzzing material to length. But it worked very well. I do know 5 flute endmills do not like high radial engagements though.
Why would he want to use an endmill and do all that roughing work? That's what roughers are for. The endmill for finishing will last much longer.
Jon don't forget to upload the video (this part) with threading.! Thank you.. Nice Job
chip recut on the finish passes can be eliminated by going conventional instead of climb milling
As a machinist myself I was taught many times to never blow chips around while the machine is changing tools.
Like to live dangerously!
It's more about blowing chips up the spindle and fucking up you machine/part/tool/tool holder.
Yes, I understood what he was getting at.
So it's not about living dangerously, it's living stupidly.
Sure! You're welcome to behave however you'd like around your machine.
Very nice part.
Airlines...the bane of a machine tool service engineer's life...you'd be surprised where swarf gets blown...
すごいですね！
Great video, what vehicle does that filler cap fit on? Also, what is the total time start to finish for each cap and what do you charge for them?
It's best to avoid blowing chips around when the machine is changing tools. Chips are prone to get between the tool holder and the spindle taper. That causes tool runout (not good) and if the chips weren't soft aluminum could be hard on the tool holder and spindle. You can enable setting 42 on a Haas to automatically pause after a tool change so you can inspect or blow parts off, then resume by pressing cycle start. It's similar to M01 but you don't have to have M01 in the program.
these guys are "engineers" aka HACKS. you are talking to the wind.
Bravo!
Good job!
very nice dude!
nice job
CNC machining is speedy and accurate. The only problem is initial cost is higher.
Makes sence. We all need a little more HP in our machines. It IS a nice looking part btw and hell'ya...think of the things you could do on the machine needed to make 10,000 pieces.
Try using an uncoated 3-flute endmill. Should get much better results.
how do u make the thread for screwing in? inside of the pocket?
i would be happy if i could listen it in my shop...:-)
What's your opinion of that Shars vice?
we have a TM-1 in our shop with a 4k rpm spindle, although we were able to tweak the parameters to get 6k out of it, it sacrificed the torque a little, but ours doesnt have the flexible slide cover in the back, we call ours "Ms Piggy", because it makes a huge mess. (especially when flycutting) it throws coolant everywhere. lol
If the probe sets up Z-axis, how do you tell tools where the Z is?
What type of coolant is being used?
That's whut I was thinking "pat" as well as the threading . this is a cap of some kind right?
Haas page took me here, really nice part! I guess, as it's a cap, that needs some sort of threading? Or is that the finished part?
Very lovely part, cheers :)
Hi. Nice video. Which CADCAM did you use to design and manufacture this component? Thanks.
Why does the probe/edge finder have to come around so often? is it checking if it moved?
What is coolant made of?
why do you center probe after flipping it around? i mean it is centric clamped :)
¿How much progress and speed?
Very nice work!, That is a well programed procedure, how is the cap secured?, threads must be made on a cnc lathe?.
See the other video linked in the description with threading! It's secured with custom aluminum soft jaws.
Why do you probe the part each time? It appears that you cut the form jaws which implies that you would already have the x-y-z fixture offsets. The 1st side doesn't matter so much but by re-probing the 2nd side, especially raw billet, you are losing your concentricity between the 2 sides.

@ 00:40 I get a flashback of Doom when the doors open.
I'm ordering a MM2 and have been on the fence about the Renishaw probe option until viewing your video. It looks quite handy. Still at $5k I dunno.
If you're using your machine for any kind of production work its an absolute must.
I've never seen a machine vise with a base like that before...
Are threading it? If solo vid!!
Think of how fast that could be made today with a 4 axis lathe.
Nice
Wow
If you use the soft jaws as the datum when you flip the piece for second op it should be true.
Your TM-1's sheetmetal is quite rattly when the axes are moving.
Excellent observation

please show this outside programmer
No threads!?

Now chamfer the scallops on the backside of the part. (he he :o)
Was also looking forward to seeing some threads, are you doing that on the Lathe?

Awesome, brother but it needs outside threads don't it?

@@JonProce you're ignoring the part where your soft jaws G54 won't change though
you bypassed the door safety
I do that at my job they would fire me XD
I like the vise jaws you got there
No door on a toolroom mill.

i can only imagine the mess you got to clean 0.0
still nice video XD
+Jon Proce Door and cabinet is an option. My TM-1P has one.
Cool vid!
But that would only take less than 3 minutes if you had a CNC lathe with live tooling. Just saying.
What if he hasn't got a lathe with live tooling. Just saying
The second part could have been done faster (and better) on a lathe.
job clamped in soft jaws,i think no need to take datum one more time. it is only
2-3 minits machnineing work.

Man, after watching a lot of Brother machining videos, anything else seems really slow!
seems like coolant needs re-fill..
+vergil albia That's my main complaint about the TM-1. The coolant tank is way too small. It runs out before the coolant can get back to the tank. Keep meaning to make a bigger one for mine.
It's that aluminum?

Threadmill it bud
That should only be a 2 or 3 min run. looks like you use corn cob cutter for hogging. just use a basic 2 flute end mill all the way.
No program is perfect. We're limited on this machine by slightly worn spindle bearings. Heavy MMRs result in chatter along the Y axis.
Jon Proce i can see why the machines wore out, you are part of the too fast too hard club. slow the fucking machine down! all those hard stops and starts are hell on the machine.

Hooray for green button to shut up tool change alarm. haha
I want one lol
nice machining but If this is a mass production you are waisting alot of time :D think you could do this 10x faster on a cnc lathe.
only if your lathe has live tooling. what a fuck wad.
Be nice to your probe! What the hell are you doing to that poor thing?!
you forgot the thread lol

hi iam from india iam studing in cipet course dpmt (diploma in plastic mould technology) what i want to know what are basic pls help me
why r they pouring milk over da metal?
It's coolant.
small children drinking coolant?
TwoForFun vitamin D is good for the Aluminum...keeps it hard. I drink it and it does the same for me. Do you want some 2-4-fun?
i would like to try to drink that but will I become aluminium?
Coolant is 93% water give or take
I could have made the same part but better in 3 minutes.
Skip the rougher dude it's aluminum.
Such things can be disabled.
I don't think you needed to probe it twice. The part is already centered with the first position. You're also probing on rough stock anyways. Not the best accuracy. Also, why in the fuck are you blowin' air around while it's doing a tool change?? Probably getting chips in the taper.
That rough stock is exactly why it does need to be probed twice. Think about what happens when it's flipped and clamped back in the vice.
+Jon Proce Oh right. I was thinking somehow both jaws move to center.
The air being blown around comes out of the spindle taper, for the exact reason of keeping chips out
