Hello,
I am looking to Gcode a basic arc, however I have no idea where to start, I have written taper, and (thanks to Graham) doubble tapers so I suppose an arc is the next logical progression. I know they use the I and K values however this is the limit of my knowledge.
If anyone has a straighfoward example they could share or code somthing up quickly that would be great.
I am useing a small sherline cnc lathe.
Cheers,
Andy

Check out chapter 10.7.3
It should answer most of your questions.

G00 X0 Z0 (move to start point)
G03 X10. Z-5. R5. (form rad)
G00 X50. Z50.(rapid away)
