Re: [CAD_CAM_EDM_DRO] Re: Cam track help!

No problem. Please define all of your parameters. This code will assume
that you get the full width of cut with a single pass. Do you need multiple
passes to get the depth? What step size in degrees would you like? If you
get me the specifics quickly, then I can do this right away. If you wait 20
minutes or longer then I will have to do it when I get back this evening.
Either way, I will do this and it should only take a few minutes.

Please let me know ALL of the details. You mentioned "pitch" before, do you
mean amplitude? How far from one side of the wave to the other do you want
(this is twice the amplitude), and how many periods?

You can e-mail me directly at dan.statman@...
