Example: Concave cylinder machined with spherical cutter
Program sequence
This program functions only with a spherical
cutter. The tool length refers to the sphere
center.
The contour of the cylinder is approximated by
many short line segments (defined in Q13). The
more line segments you define, the smoother
the curve becomes.
The cylinder is milled in longitudinal cuts (here:
parallel to the Y axis).
The machining direction can be altered by
changing the entries for the starting and end
angles in space:
Clockwise machining direction:
starting angle > end angle
Counterclockwise machining direction:
starting angle < end angle
The tool radius is compensated automatically.
