Will it Cut Aluminum? Shapeoko Pro

This video is something I had been putting off until I got a bit more experience with the machine under my belt. Though it was not perfect it did yield usable results and it was super cool seeing the machine fly through the material. Turns out, that when you forget to turn of radial stock to leave on the adaptive facing operation, you end up with a fin in the middle of your part. Also, when you are doing step overs, it's one thing to run a 92% step over but quite another if it turns out the actual cutter tip is not .25". This tool is ground slightly under .25" and thus resulted in this fin at the serious step over. Going forward, I'm going to compensate for this by measuring the tool cutting diameter to ensure I get proper cutting action. All in all the machining went super well. I'm going to bank this one and I look forward to the aluminum projects in the future.

My name is Austin and I’ve always enjoyed building things. My childhood Christmas stockings were filled with bulk supplies of scotch tape so I didn’t use up all of my moms as I made various paper lightsabers and more. The things I wanted to build grew to be too complex for scotch tape and trial and error so I decided to study Mechanical Engineering to better understand how to make things. I specialized in mechatronics and manufacturing and I’m now about ready to graduate so I’m putting my education to work by building all the projects I haven’t had the time to do while in school. From climbing holds to signs and many other projects, I’m going to bring you along the journey through each build, and show you how I go about making everything I want to make. I hope it inspires you to get out there and build things and gives you a chuckle or two along the way. Thanks for watching!

I would double check your endmill diameter in your cam profile. If it is set to large it will leave the wisps behind because it assumes they were cut by a larger diameter endmill.

Just rewatching this golden video as I attempt to dive into cutting aluminum on my MPCNC. I gotta say I'm disappointed you don't have any new cnc related videos lol Or better yet a way to chat/discuss cnc related projects on a discord of some sort. You should most certainly rectify that shortcoming ;) lol

@edenochoa2337 2 года назад

Great job. I’m a cnc machinist and also went the mechanical engineering route like you did. Glad I found your channel. Some advice, lie to whatever cam software you use and reduce the tool diameter and the little towers it left behind in the adaptive tool paths, or alternatively reduce the step over so the actual tool diameter covers all of it. It looks like a 1/8 flat so just put the tool d a thou smaller

@edenochoa2337 2 года назад

And the little towers will disappear when you lie to the cam*

@AustinConrad 2 года назад

@@edenochoa2337 thanks. Ya I think just a simple reduction in the step over should get it done.

Single flute is definitely the way to go with cooling, and a big cutter -- for sure. You will not generate a lot of heat and chips will clear out on their own pretty easily. When you get into finer details, and smaller cutters, the high RPM becomes impossible without coolant. Hence I ditched my mdf spoil board (not a shapeoko, a custom CNC, but same issues) -- so now I'm rebuilt my CNC bed with 2020 extrusions and will be bolting 1 inch thick HDPE to it -- I tried using HDPE as a spoil surface on top of MDF, and works a treat, holds threaded inserts, holds tracks -- works with double sided tape, and with blue tape with CA glue. With a full spoil bed being HDPE, coolant is not an issue.

@AustinConrad 2 года назад

Nice! Only issue i think I'll still run into with the swap is the fact that my entire machine interior is bare plywood so it might still have to wait. Thanks!

@kazolar 2 года назад

@@AustinConrad i made an enclosure for my CNC converted mini mill, and I just painted the plywood with marine paint. That takes care of any issues with coolant - plus if you're just doing mist, not flood, just the spoil board gets wet.

@welderboy14 5 месяцев назад

Have you had any issues with the belt drive? I know i want a machine with linear rails but I can't decide if ball screw is worth the added cost. If all works out, I'd likely upgrade to a larger machine.

@AustinConrad 5 месяцев назад

Belt drive is faster and cheaper than a ball screw with a con being the rigidity. Depends on what you plan to cut and how fast you're trying to cut it. Personally I haven't had the need for ball screw that justified the cost and many hours of milling later, no issues with the belts. Have fun!

@joshuabray37 2 года назад

I cut some aluminum coins on my shapeoko 3, with a 1/8in tapered bit (it has a needle sized tip). It did an excellent job. I just had to cut very SLOW (or I'd snap the bit)... I used double sided tape and that worked great.

@AustinConrad 2 года назад

Nice! Ya the cutting forces get higher the faster you try to move through the material so the better the work holding needs to be. Fortunately double sided tape gets the job done fairly well.

@AustinConrad 2 года назад

Not sure exactly what you're cutting out of them but some double sided tape and tabbing should work just fine. Be sure to deck your mdf waste board first and check your offsets. Also be prepared to give it a few trys.

@tylernewcomb1431 2 года назад

I am curious what your optimal load was for the adaptive roughing. If it is too high the path will leave whisper lines in the part once deflection is added to the system.

@tylernewcomb1431 2 года назад

By the way here is a video of a less rigid machine cutting aluminum at a very high MRR. Your machine should be able to handle this recipe. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-zefnrPRvc9Q.html

@AustinConrad 2 года назад

The settings are in the video. 0.23" which turned out to be a bit too much. I dont think it was deflection, I think the tool isn't truly. 25" cutting diameter. I plan to find out with more testing

@Fencer85 2 года назад

Look into mitee bite work holding, and you might try compressed air for cooling. Yeah it’s not gonna lubricate the cut, but it might keep temps down long enough to do a extended run

@AustinConrad 2 года назад

Ya that tape worked out great. I've thought about the compressed air,I just don't have an air compressor big enough that it wouldn't be going off the entire time.

@giuliobuccini208 2 года назад

I do not know about Zirconium, but Diamond coated bits are the key for cutting alu without coolant. TA-C are even better. (Today's industry try to reduce - or eliminate at all when possible - coolant usage for environmental reasons.)

You don't need coolent to cut aluminium, you need the right bits to cut dry. DLC or similar coated bits will give you this result.

The shapeoko 4 is also pretty darn capable but the linear rails of the pro add a bunch of ragidity. I would say it is likely just going to require a slightly different recipe but keep track of chip load so you don't weld the tool and definitely go for a single flute. Good luck!
