Path milling (CYCLE72)

Function
You can machine open or closed contours with the "Path milling" cycle. Before you can mill
the contour, you must enter the contour. Machining can be performed in either direction, i.e.
in the direction of the programmed contour or in the opposite direction.
For machining in the opposite direction, contours must not consist of more than 170 contour
elements (incl. chamfers/radii). Special aspects (except for feed values) of free G code input
are ignored during path milling in the opposite direction to the contour.
