Cryogenic machining?

I spotted this last week on the Applied Science YouTube channel and thought It might be amusing to someone here. I've been looking for a way to cut some multi layer shapes out of neoprene, but I think the shope might get a little nervous if I started super-cooling the mill. Anyone here up to see if ...

Re: Surface probing for milling warped stock?

Ok, I'll bite. where in fusion-360 does one go to create a facing operation ? But honestly this sounds like a lot of work. I would try to make it flat with either a jointer, handplane, or similar. Or use the cnc and run a facing operation (fusion 360 has that built in, but you can do that with most ...

Re: Repeatable starting point?

Good Idea. Thanks for the tip. I would take a guess and say this only works if you have the same bit? Another technique (minor variation on Edward's) which I tried while working on the H.O. Studley calipers: - drill a hole in the fixture at the origin point --- when it's time to use the fixture manu...

Re: Another Dial Indicator Bracket

Silly question, do mill with that on? Or remove it?

Re: Roughing, Finishing

I think this kinda falls under the Roughing and Finishing subject line here, feel free to move it admin. I have a procedure question on after you have a set of Roughing and Finishing jobs that have been exported from Fussion360, Aspire, or Cambam. if I run two jobs, a roughing and a finishing, the f...

Re: X and Y fine Tuning

Sorry, late response. The "odd" error I was seeing was an increasing distance between a few sets of holes in the +X axis. I should have rotated my parts long side 90deg and tested to see if it did the same in the Y axis. I changed the X and Y axis "Travel per Rev" settings to 40.0 and it seems to ha...

Re: Thoughts on the Wolfgang Engineering WW-650?

I have one of these, but never tried it out on the ShapeOko-2, not even sure how I would go about mounting it. Its a nice little spindle. Noisy little beast as it uses a RC brushed motor. It's smooth and has a very tight run-out. Only issue I have is the collet is non standard and I'm limited to jus...

Re: My first cuts. (Letters for wall)

Thanks for the info, I'll have to see if I can locate some at the Lowes next door. still working on what speeds I can use. I had no problems at all with 650 for the speed and 5mm depth per pass though. I had my dw611 set around 3 for the speed. the foam is an insulation board that can be found at a ...

Looking for a review of a few endmill bits from toolstoday

I've been looking for a few smaller bits to play with and a crazy guitar builder at my local Techshop suggested I look at toolstoday.com, specifically http://www.toolstoday.com/p-6225-solid-carbide-cnc-2d-and-3d-carving-tapered-ball-nose-conical-ball-flat-bottom-end-mill-zrn-coated-router-bits.aspx?...

Re: My first cuts. (Letters for wall)

Looks nice. I have someone asking me to do something similar with a bit more detail across the Z axis. Could you elaborate on the foam, bit, and feeds and speeds you used for that foam? Here is my first project, keeping my daughter happy. These are cut out of foam because I figured it would be a nic...
