contour cutting depth 5 mm, surface
machining feedrate 300 mm/min, cutting direction
feedrate 100 mm/min, use G41 to activate
compensation, use G1 to do rough machining, back
to the machining plane at the end of the contour,
approach path is along 1/4 circle in space, length 3
mm, the parameters of feedrate//path/length for
retraction and approach are equal.

length 40 mm, width 30 mm, corner radius 6
mm,groove base point coordinate (X36,Y24.1),
angle between groove vertical axis and plane X
axis is 15º), finishing allowance 0.1 mm, feedrate
surface machining and cutting direction machining
is 300 mm/min, milling in positive direction, rough
machining, use G1 vertical groove center to insert.
