Program sequence
■ This program requires an end mill.
■ The contour of the sphere is approximated by
many short lines (in the Z/X plane, defined via
Q14). The smaller you define the angle increment,
the smoother the curve becomes.
■ You can determine the number of contour cuts
through the angle increment in the plane (defined
in Q18).
■ The tool moves upward in three-dimensional
cuts.
■ The tool radius is compensated automatically.
