DIY CNC Turret Lathe FINALE! WW225

- เผยแพร่เมื่อ 20 พ.ย. 2018
- SPOILER ALERT: IT WORKS! We wanted a cost effective way to produce fixture plate plugs and building this turret lathe was the route we chose. Along the way, we decided to go with an injection mold. Still, we wanted to follow through to show that it CAN be done. There is so much to learn from building a machine tool! Today, we'll machine the upper and lower spindle brackets and use our laser to cut acrylic for the legs and belt guard. Then, it's on to assembly. LONG LIVE THE TAIG!

Nicely done. Also love the commentary style, speak when there's something to say and just let the footage run when there isn't. Many TH-camrs seem think they have to talk all of the time. Well done.
This DIY lathe series is so great - easily could be part of the curriculum for a college level CNC course. Lots of different toolpath strategies, and great problem solving.
Awesome work on the DIY lathe Ed! 👍🏻
Including Abom79 cameos? Who do you think you are, This Old Tony? ;-)
Nice video, and project.
PS: The phrase "Clearance is clearance Clarence" needs to be on a T-shirt!

I have noticed Utube's technical vocabulary is growing thanks to AVE.
He's my kind of Utube influencer.
Roger, Roger!
I still have my Taig mill. Nice to see you retasked the motor for it. Great series!
loved watching this project come to fruition. hope to see more like it coming along soon.
I have to say that is one fine piece of machinery. Very well thought out and built. Thanks for sharing the ride.
Very nicely done Ed! Most all projects are more about the learning on the way!
ATB, Robin
I love this automation and the designing that went into it. Abom cameo was great. This Old Tony are great videos.
Great job! Loved watching the series progress up to this point.
I love these automation videos! I am glad you finished it even though you went a different route for the caps. Very impressive build!
His throwaways projects would be my masterpieces
That scalloped chamfer could have a video all of it's own. So neat!
I learned when spot drilling you want to use the spot to create the chamfer for the hole as well. Additionally, when spotting you want to have a short dwell time so the tool has enough time to make a full rotation at depth.
What can I say? It’s functional and looks great. Good engineering project, you have some serious skills.
That was impressive. Great job. Much better than the injection mold project.
Well done Ed great job! You don’t have to tell me about designing and building your own CNC machine. 2 years in and still not quite finished !
Wonderfully done Ed. Your talent is obvious. Congratulations on a great series. R
Ive loved this series - it was a bit long but showed a more complex task through to final product. Its such a shame that it wont actually be used! More of the same please!?
Good on you for your persistence! The only reason I can think of for those slow toolpaths is too-finely-segmented curves making for a lot of little moves; maybe there's a way to see that in the code.
Wow this is amazing work! Thanks for sharing the files this is gold!
What a fun project! Hope you guys find a use for it down the road.
Such a neat and useful machine! Looks and works fantastic. I would love if you guys find a something it can produce for your business.
This is so damn cool! Bootstrappers dream! Why outsource when you have the tools to build a dedicated machine for the job! Great job guys! Would of loved to see this thing fully completed with the bells and whistles but none the less its still awesome and great video series!
Fascinating project, great result. Your video production and commentary style are very professional - just the right balance with the commentary content.

14:44 your turret lifted and rocked from the parting forces. That likely could lead to some irregularities in parts. 15:15 it wobbles again on entry of the drill bit. Maybe adding a support to the top shaft sticking out of the turrett would help stabilize things.
Noticed that. Slight amount of play likely at the point the turret rotates. Surprised that wasn't addressed
I am amazed at the tape holding the aluminum block for milling! We use tape for holding flat plastic, and it is an amazing pain getting all the coolant off so it will stick at all. I use hold-down clamps instead, even if I need to move a clamp to finish the part, so much easier than having the tape come apart.
So glad to see this finished!
If you were to put this in production, any reason you wouldn't part off during with the ball bearing insert tool in place to save the extra cycle of having a separate ball bearing insert and parting support?
I use these HexPlus vom Wera for years and I love them.
Wonderful workmanship.
@11:06 clearance is clearance but man that pucker factor was astronomical for a moment there.
It's pointy. Worst case you get an unwanted line down the top of the part.
just fininshed watching this video and that little lathe is amazing!! I will have to go back and watch the rest of this
You have the workshop that I want!! LOL. Learned a lot from you!
Thanks for sharing, it's a beautiful machine.
Really cool build guys. I hope you find a use for it.
Great video you created a Capstan lathe im sure you gonna find a new use for a great piece of kit
Awesome project, awesome work.
For the slowing down in corners in a 2D contour, look in Passes ---> Feed Optimization. That will control any changes in feed rate through corners.
Excellent! I envy you brother. You have such nice equipment to do this type of work.
Excellent work.
Liker-Subscriber-Notifier - This was a great build! Be nice to see that puppy running with the barfeed! Love the "Clearance is Clearance, Clarance - and showing off the chamfer command on the bolt hole
This is the kind of parts i do with my Hardinge DSM-59 ;) Well done!
Great Vid....It's pretty cool.
Awesome!! Now y'all using that education, i must admit i am impressed. Now get to reloading automatically and we're done.
And i learned a lil....because i was thinking efficiency was a hvac thing, like the higher i am the more efficiency it has....or something like that i had no idea i was laziness... but it makes sense because the more efficiency the condenser/system has the more it fucking breaks and the longer it takes to work, txvs and set up scenarios im doing a job and gtf im not trying to do something im not there to do
Don't care whether it is being used or not, this is an awesome project!
Such a nice machine in every way... :D
I think that’s the coolest project you guys have done. Very fun to watch! Makes no difference if it never gets used.....you made your own CNC turret lathe. How cool is that?
I have NEVER seen you guys crank up the Tormach that fast. Are you guys finally watching Titan ? Great work. I see John had his fill of this project... ;)
Wera tools are top notch. I have their Allen's and their Joker Wrenches so far. Best tools I own. The Jokers are excellent, except where they aren't, but where they are they can't be beat.
For the slowing down in the corners: you should maybe check the settings for overlapping contours (or however it's called) in the machine settings. Normally there's a look-ahead-function, that reads the upcoming lines of G-code and puts in deceleration and acceleration sections into the transition. This is all to avoid an excess of jerk and make the movement more smooth. There are different types and often you can also change their behavior with some parameters (like max arc radius, max deviation from edge etc.).
If you want the tool to follow the exact path with sharp corners, the movement would have to come to a complete stop in the corner and then ramp up again. You often get better results by allowing some roundness in the corners, but instead getting a more smooth toolpath.
It's G61 / G64 in LinuxCNC-based systems
Fusion 360 CAM contour in the passes tab there is a feed optimization option, this specifies that the feed should be reduced at corners. You might want to check that out for your feed slowing down at the corners.
@ 9:56 I believe since you're increasing surface contact by going into the tighter radius, it maybe slows down to keep your chip load steady?
would have liked to see more about the lathe.
other than mill work is basic stuff.
thanks for sharing.
AVE can really learn a ting or two about surface finish from you...
You guys should do a video that shows all of the projects that you have done like the automated 440 part feeder and how well they are working after being used for awhile.
Cool project guys! Looks perfectly suited to the task it's designed for. Well done! :)
One thing you guys might like (since I've seen you use Arduino stuff before) is a new controller platform from Automation Direct. It's their 'Productivity' brand PLC but uses all Arduino components in industrial hardened packages. Looks pretty inexpensive too.
Epic project! Just epic. And as for the rubber plugs, wouldn't they wear faster than these? I would like to see them made in this turret lathe just for the cool factor.
hahaha loving the abom cameos on almost every machining channel
When in CAM, for the upper bracket, see if you have smoothing turned on
Where did you get the tape and glue caddy shown around 55 second mark? Looks like acrylic and probably laser cut, are the files available? I'd love to make one for me and a friend who just ordered a desktop cnc.
Slowing down on the short arcs almost looks like the machine is acceleration limited -- I would expect that it's a problem with the machine trajectory planning rather than the G-Code. That might be worth contacting Tormach about.
nice work... Even if the machine isn't immediately useful the learning sure as hell is :-)
Great Vid!
Maybe your controller cant keep up with the program lines. Did you check the smoothing box in fusion? With this checked, the number of coordinates in a radius is reduced, which leades to less program lines.
Grtz from the Netherlands
With 1000 block look ahead that it's meant to feature, I think it should be fine with some very fast code.
Well done.
Nitto makes two sided machining tape. Ive used it many times to stick down blocks and very thin sheetmetal. Releases with rubbing alcohol.
great video .. and as for those slow tight corners .. NYC CNC already made video about that i think, what is happenning is that toolpath in that tight curve gets split up into many short paths .... so procesing that is hard and if your machine computes acceleration for each of those short paths, it will never reach the speed it could otherwise.
The feed rate actually needs to slow down in tight concave radiuses due to the actual feed rate at the cutting edge being larger than the programmed feed rate (which is at the tool center) because their distances from the tool path center are different.
Scroll down to "Two axes ramping - circular. Part 3" at this link to find a better explanation: www.sandvik.coromant.com/en-gb/knowledge/milling/milling-holes-cavities-pockets/pages/ramping.aspx
I somehow doubt it. PathPilot is based on LinuxCNC and runs on a powerful x86 machine, not some microcontroller.
@@Anonymouspock still it doesn't look more than one cut ahead AFAICT. I've also seen slowdown in tight corners with pathpilot out of fusion, more than feed rate compensation would demand.
Yes, you are right @Halvor Huse Aasen, but it seems it slows down too much to be just adjustment for this. If only i could find the video i remember... it was made by John, he was making some part and somewhere in the middle he noticed this behaviour too. After inspecting G-code he found tens, maybe hundred points on the slow corner. Some form of smoothing helped to reduce it to just few and it ran way faster. At least its just my amateur idea, you guys are probably more experienced :)
9:26 why do these passes in that direction, when they could be done in less passes? I noticed a few that could have been done at a 90degree angle and done in like 1 pass
On that drilling concern, for plastic put a small flat parallel to the Z axis on the leading edge of the flutes. It won't want to dig in and breaks the chips very well too.
I am sure this is late but I dont see an answer about your tight radi question yet. As you were using a contour toolpath, my assumption is that you have Feed Optimization turned on in the Passes tab.
One of my favorite options for the contour toolpath actually but slightly less useful if you are doing a full slot. Due to contour not being an adaptive (or trochoidal) toolpath, it will not maintain a constant chipload and a great way to overload and break a tool is to come into a corner where the tool will go from having say a 10% radial engagement then jump up to say 40% in an inside corner.
Feed optimization allows you to specify the radius of the inside corner where it enables the slowdown and what percentage of feedrate you would like to use in that corner.
If you are using a smaller tool to do a finish contour on an inside pocket and the radius of the previous tool was larger than a feature in the pocket, feed optimization is key to prevent snapping that small finishing tool. Additionally, you could always go in with a rest machining adaptive before doing the contour with that same tool to reduce the chance of a big change in tool engagement.
Hope this helps! Feed optimization is a huge help when you want it on but can give some confusing looking toolpaths when you don't.
Great machine, bravo!!!
See if your post processor allows for g02 / g03 moves, that might be able to help with the tight radiused corners or possibly smoothing
You are multi skilled person. Wow
Very good work. Thanks for sharing
DIY........with expensive shop machinery at your disposal.
Beautiful work.
Lovely!
that fly cut pass at 6:50. I was convinced I was going to see it crash right into the vice.
WERA Handtools made in Germany are really accurate and innovative. The handles of the allen keys are coloured to find them better on metallic surfaces. Can‘t tell how often i lost or forgot allen keys on or in machines before i had the coloured ones...
🤔 Are you guys producing that?
What would it cost shipped? 😏
Really awesome video!
Wow light cutting. I’d run that in two passes. End mills were using can run a .7Doc at 65ipm. Maybe one pass, lol. Not a Tormach though it shows the rigidity for sure watching this.
Maybe this could still be used to make optional/extra-cost plugs out of different materials for those that are willing to pay 10x (or more) for something special. Either way, A+++ for effort.
I’m sure you know by know (since I learned this on NYCCNC lol, HAAS tip of the day has a good explanation too) but for others the slowing down on the corners may be called corner compensation in fusion 360. It’s a good thing that provides constant cutting forces by compensating for the diameter of the end mill around corners. Without this the code would be generated based on the center of the bit, fine for a strait line, but think about the size of say an inside corner arc on a part verses the smaller arc made at the center of the end mill. With that in mind if the speed didn’t slow down you would be cutting at the correct speed at the center of the end mill but it would be much faster at the edge of the end mill. This could result in ugly corners, broken bits, and pullout of the end mill or the part.
Did you guys ever try to measure the runout in the spindle? I'd be curious to know what kind of slop you get in a diy spindle like this.
Great machine!
At Uni we ran a CNC router that,would slow down on splines, arcs didn't slow the towpath down as much. I would look at how the 2D path is generated.
Very cool, maybe it's not making what the initial intent was, but what else could you use it for? Im sure you can think of something.
Your videos certainly worth the time to watch.
Nice job! Again.... :-)
Good project ! Love the haimer self setup .lol ,in other note , are there any cad files of this machine ?
9:33 It may be because of data straving. Many machines can read up to 40 lines of code per second, if you try to push harder it starts to “slow down” (it actually shakes). There is an option in Fusion 360 to smooth the toolpath. I think it replaces splines and uses arcs instead.
Beautiful job
Wth...wowwwww...veryyyy cool machine Sr.
Could you kindly share how long it took you from conceptualisation to first successful run? How much of your working week did you spend on this project?
Just wondering, how much Z travel does the Tormach have? I’d love to have one in my garage. Also, for the best hex keys, Bondhus has always been my go to. Also, their rubber handled T set is pretty nice. The rubber does pretty well in a coolant heavy environment, and I’ve never stripped them out.
If you have .050 of clearance, might as well be a mile. I’m happy if I can get a piece of paper that’s more then enough.
amazing project
Very nice video! can you share where to buy that centering tool? is cool and time saving
RE: small radius slowdown - this could be what's happening:
In 3D printing, by default, "sliced" curves are comprised of short, straight, lines. It would stand to reason that smaller radius curves would require more, (shorter) lines to describe them.
The 3D printer control software Klipper has a plugin called "Arc Welder" that converts curves into genuine arcs, (so you're no longer limited by how many moves/second the mechanics are capable of). I would be surprised if Fusion 360 didn't have this function built in.
The other thing to look at is the increased number of X-Y move commands might be straining the bandwidth of the communications channel between the the CNC controller and the motor drive electronics boards.
Slowing down happens when fusion Posts a lot of G01 coördinates, turn on smoothing wil help reduce them.
I like PB swiss allen keys a lot, the ball geometry is superior to any other keys I've used, they cam out of the fastener instead of binding like typical ball ends. They have a black friday sale tomorrow fwiw.
Is the slowing for tight radii due to some acceleration settings maybe being too conservative?
Adam is becoming a Cameo star lol
