My First Part

Postby ToddZ » Wed Aug 07, 2019 5:39 pm

Here is the first part that I've milled out entirely using code generated with FreeCAD. I had always used other CAM products to generate G-code for our CNCs in a wood working shop. However I have needed to make a few pieces from aluminum and the usual wood working tool path strategies just don't work very well for cutting out metal. What I needed was a CAM program that could generate Adaptive clearing tool paths and our CAM package does not offer this. So I decided to give the Adaptive tool, in the Path Workbench of FreeCAD a try. it worked splendidly, especially once I figured out how to set up the post processor for my CNC machine.

The part below is only about 2 inches by 5 inches and was cut from 1/4inch 6061 aluminum plate using a 1/4inch carbide O-flute up spiral bit, and fixtured simply on a vacuum table with MDF spoil board. The mill out finish pass had 4 dressup tabs to hold the peice to the stock when cut free.

There is no better proof that things really work.
