Graham,
Ok, I have that. Now, imagine that I want to cut a series of these 20mm circles around a face that is able to rotate on the A axis, this would form a ring of 20mm circles, the spacing and overlap dependant upon the number of these 20 mm circles that I cut, as well as the radius of these circles from the center of the rotation of A axis. I know also that I could simply advance A for each subsequent 20mm circle, but is there not a way to coordinate the motion of A and Z to scribe the circle? In other words substituting the motion of A for Y, which in itself being rotary, would require some sort of interpolation being that the feed would be constantly changing as the cut moved near center and out again. I just thought that the formula axis correction could be used to make this adjustment in order to scribe a circle on the end of a cylinder held in a rotary table.
Thanks, Woodeye
