N490 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 ap-
proach are equal.

N560 milling rectangle groove (depth 3
mm, length 40 mm, width 30 mm, corner
radius 6 mm,groove base point coordinate
(X36,Y24.1), angle between groove verti-
cal 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.
N570 repeat N600 milling process, the
difference is the machining allowance.
