My plans for the near future involve adding a 4th axis to the mill, as I found a good deal on a used Troyke CNC rotary table. It also has a DC servo motor (no control). It is not working, but looks like I could fix it. i

I am very critical about many linux things, but EMC2 and kernel are not among those. i

For those companies that can afford 'real' CNC machining centers, and quality s/w. With conversational input of tool paths and CAM tools with post-processors that spit out (virtually) ready to go G-code, you may need to do a very small amount of math, but you certainly don't need to trig stuff out like you used to have to do. You still have to know G-code, and tweak said post-processed code usually though, and know what tools to use and the correct feeds and speeds for whatever material, and the best order of ops for each piece, etc., so machinist skills still apply.......just not the math so much. |
