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.
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 RUclipsrs seem think they have to talk all of the time. Well done.
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.
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.
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!
Fascinating project, great result. Your video production and commentary style are very professional - just the right balance with the commentary content.
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
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.
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
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.
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
@@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 :)
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.
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.
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.
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.
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...
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.
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.
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.
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.
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!?
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?
4:20 it's called functional laziness. But a more reliable way to do that is by using your 3/8 chamfer mill as a stop. MDI to your work offset x0 plus the tool radius (g0 g90 g54 x.188 y-.25) then handle jog it down until the shaft of the chamfer mill is below the surface of your part. push the part against it, close the vise and handle jog the tool out of the way. It can also be added to your program for automation purposes. putting a stop like that on the moving jaw like you did is a generally bad idea because you don't want your stop to move. Moving is the exact opposite of what you want from a stop. Also putting a stop against a part that has already been secured isn't always accurate. As a rule, you should setup your stop, put the first part against the stop, secure it and then find the zeroes. This ensures repeatability.
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.
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.
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... ;)
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
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!
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 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.
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.
Ed, is there any particular reason why you spend a lot of time with multiple passes using the fly cutter making multiple passes in Y. ? when one quick pass in X could get the job done ?
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.
the slowing down could be due to arc tollerances or interpolations into to many small lines for the controller of your mill, i had the same problem on my diy mill so i just reduced the arc tolleranc in fusion and it was alot smother
So, we have a turret lathe made from aluminium using form tools with some auto features added.....hardly CNC but quite handy if you don't want to swing the levers yourself etc.......I think the design could be totally CNC'd......probably is going to be but I don't see it with the turret as the main tool holder.
Re: slowing in corners/tight radius sections. I'm pretty sure this is obvious to you but do you have "Feed Optimization" checked in the toolpath 'Passes' tab in Fusion? If so, that will slow down the feedrate (intentionally) under the conditions you encountered above.
Why, oh why didn't you finish this? It's great work but such a shame as one of my main interests was the automatic bar feeder. Are there any working examples available. Cheers.
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.
How you want build feeder? Old german wood automatic lathe have interesting system. 2 collets, one in head mechanic closed. Second one is spring always closed. When first is closed second one move on dowel back. When first is open second move forward fedding dowell.
It appears you are cutting a radius the same size as the End Mill. If you ran into that radius at full speed it would chatter to all hell. Use a larger radius or use a smaller End Mill and the feed rate would probably not slow down. This is just a guess. btw NICE JOB
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
Don’t really know what im saying but the slowing down part at 9:43. Could that be because its a thight corner and that the machine is doing that for less vibration? Maybe a change of parameter would help. Let me know if you know why and how to change that. Cheers
4:15. Using a Stop on a moveable jaw isn't really a good idea. They tend to tilt, and shift position. I would have had the part flipped around. Either way, this video turned out great. :)
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.
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.
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 RUclipsrs seem think they have to talk all of the time. Well done.
I have to say that is one fine piece of machinery. Very well thought out and built. Thanks for sharing the ride.
I still have my Taig mill. Nice to see you retasked the motor for it. Great series!
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.

Awesome work on the DIY lathe Ed! 👍🏻
That was impressive. Great job. Much better than the injection mold project.

Noticed that. Slight amount of play likely at the point the turret rotates. Surprised that wasn't addressed
Very nicely done Ed! Most all projects are more about the learning on the way!
ATB, Robin
Great job! Loved watching the series progress up to this point.
Awesome!! Now y'all using that education, i must admit i am impressed. Now get to reloading automatically and we're done.

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.

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 !
This is the kind of parts i do with my Hardinge DSM-59 ;) Well done!
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.
I love these automation videos! I am glad you finished it even though you went a different route for the caps. Very impressive build!
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.

It's G61 / G64 in LinuxCNC-based systems
@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.
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.

Nitto makes two sided machining tape. Ive used it many times to stick down blocks and very thin sheetmetal. Releases with rubbing alcohol.
Wonderfully done Ed. Your talent is obvious. Congratulations on a great series. R
hahaha loving the abom cameos on almost every machining channel
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.
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.

In the tight radius the chip load spikes. Fusion is adjusting for this. It is due to engagement percentage

See if your post processor allows for g02 / g03 moves, that might be able to help with the tight radiused corners or possibly smoothing
@ 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?
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.

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.
Slowing down happens when fusion Posts a lot of G01 coördinates, turn on smoothing wil help reduce them.
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.

DIY........with expensive shop machinery at your disposal.
Beautiful work.
You generally don't put a stop on the moving jaw since it can float several thou
What a fun project! Hope you guys find a use for it down the road.
I use these HexPlus vom Wera for years and I love them.
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.
the slowing down could be due to arc tollerances or interpolations into to many small lines for the controller of your mill, i had the same problem on my diy mill so i just reduced the arc tolleranc in fusion and it was alot smother
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.
So, we have a turret lathe made from aluminium using form tools with some auto features added.....hardly CNC but quite handy if you don't want to swing the levers yourself etc.......I think the design could be totally CNC'd......probably is going to be but I don't see it with the turret as the main tool holder.

Why, oh why didn't you finish this? It's great work but such a shame as one of my main interests was the automatic bar feeder. Are there any working examples available. Cheers.
would have liked to see more about the lathe.
other than mill work is basic stuff.
thanks for sharing.
@8:16 shouldn't feed along X instead than against the jaw or the machine has less vibrations like you do?
in post processing in fusion go to arcs and radi and put it on. it should help you whit the slow corners
AVE can really learn a ting or two about surface finish from you...
Now that you are going with the soft plug would a Diresta ice pick be a good up sell?
@Ed Rees I don't know. How? ;o)
Thanks for sharing, it's a beautiful machine.
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.
If I'm not mistake it slows down on the tight radii as a high speed machining feature.
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.
How you want build feeder? Old german wood automatic lathe have interesting system. 2 collets, one in head mechanic closed. Second one is spring always closed. When first is closed second one move on dowel back. When first is open second move forward fedding dowell.
It appears you are cutting a radius the same size as the End Mill. If you ran into that radius at full speed it would chatter to all hell. Use a larger radius or use a smaller End Mill and the feed rate would probably not slow down. This is just a guess. btw NICE JOB
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.
might be slowing down in tight arcs to eliminate engaging too much of the cutter. this would normally cause chatter.
Great Vid....It's pretty cool.
🤔 Are you guys producing that?
What would it cost shipped? 😏
Don’t really know what im saying but the slowing down part at 9:43. Could that be because its a thight corner and that the machine is doing that for less vibration? Maybe a change of parameter would help. Let me know if you know why and how to change that. Cheers
nice work... Even if the machine isn't immediately useful the learning sure as hell is :-)
Such a nice machine in every way... :D
isnt the reason for the tight radii slowdown. Difference in actual feed between the inside of the cut, and the outside? Think differential
Awesome project, awesome work.
4:15. Using a Stop on a moveable jaw isn't really a good idea. They tend to tilt, and shift position. I would have had the part flipped around. Either way, this video turned out great. :)
You are multi skilled person. Wow
Cool project guys! Looks perfectly suited to the task it's designed for. Well done! :)

What’s the make and model of the small low profile vise you guys are using?
