Note
EXTCALL / EES
When calling a part program via EXTCALL without EES, the contour can only be called via
“Contour name” and/or “Labels”. This is monitored in the cycle, which means that contour calls
via "subprogram" or "labels in subprogram" are only possible if EES is active.
10.3.7 Path milling (CYCLE72)
Function
You can mill along any programmed contour with the "Path milling" cycle. The function operates
with cutter radius compensation. You can machine in any direction, i.e. in the direction of the
programmed contour or in the opposite direction.
It is not imperative that the contour is closed. The following machining operations are possible:
● Inside or outside machining (on left or right of the contour).
● Machining along the center-point path
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.
Note
Activating G40
We recommend that you activate G40 before the cycle call.
