Requirements

Call and return conditions
The G functions effective prior to the cycle call remain active beyond the cycle.
Plane definition
The machining plane must be defined prior to the cycle call. With turning, it is usually the
G18 (ZX plane). The two axes of the current plane in turning are hereinafter referred to as
the longitudinal axis (first axis of this plane) and transverse axis (second axis of this plane).
In the turning cycles, with diameter programming active, the second axis is taken into
account as the transverse axis in all cases (see Programming Manual).
Contour monitoring relative to the clearance angle of the tool
Certain turning cycles in which traversing motions with relief cutting are generated monitor
the clearance angle of the active tool for a possible contour violation. This angle is entered in
the tool compensation as a value (in the D offset under the parameter DP24). A value
between 1 and 90 degrees (0=no monitoring) without sign must be specified for the angle.
Longitudinal contour monitoring:
