Re: [CAD_CAM_EDM_DRO] Z axis circle cut

You need a Cad/Cam program. And learn how to write G-code programs. Easiest way is to take a code that runs on your machine and use the first few lines and delete all the strings with X,Y and Z values/moves. Then put in your own. Find a list of NIST G-codes on the web and that will give you something to go by. With that list and a calculator, one can program anything practically. Just experiment and see how each command effects machine movement. Just some simple G01 X2.0 F10.0 and to go back to X0 Y0 would be G01X0Y0 etc. Even with a CAM program, one still needs to understand G-codes. Because even though the post-processor generates a code, often they need to be edited. And it is imperative to go over the code and visually analyze it. Visualize and track the cutter mentally step by step. Not doing this and just firing up a program is a crap-shoot. If you have a 3-D toolpath that can be rotated dynamically will help also. I dont know what T-mill is but, if you are running a PC based
control I'd be looking at Mach2 software, its updated frequently and very easy to use.

Is there a G code or M code to make a Z axis
circular cut?

I'm trying to make a rectangular box with a
semi-circle cut on one side.

In this cut, there are spaced gouges within
the main, semi-circular surface.

These don't have to be there, but this is the
project.

I can make something that will work by turning
the thing on its side, but the little lines in
the surface I cannot think of how to make.

I'm using a sherline table top mill with the
Tmill program, ( a basic program that sequences
through g&m codes, some of them)

The part is made from nylon.


Thanks.
