Spiral toolpath to machine a cone?

[Kitwn]

Or just build your spreadsheet to generate one G2 per vertical step, and calculate away! I'm sure that that will work. But my IT background says that if a machine can do the work for me, then I'm not going to spend brain cycles doing it by hand...

Good luck either way.

I was pondering along these lines as well, a good excuse to swot up on exactly how G2 and G3 instructions work and whether Excel will export files delimited with cariage returns. The arc centres are all the same and the end points progress outward in symetrical straight lines so it should not be too dificult. If the angles match then using a V-bit will help smooth the edges but that would only be possible for very short cones with most V-bits.

You're not going into competition with OMLCNC are you? http://www.mycncuk.com/threads/14408...632#post123632
