TURNING CYCLES
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). See the following illustration for G18 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 mon
