7.6 Machining Parameters
1 – Global parameters for finished parts
ORA, ORW are evaluated in the finishing cycle G890.
Machining parameters are used by the work plan
generation (TURN PLUS) and various machining cycles.
Global parameters for finished parts
Peak-to-valley type [ORA]
Type of peak-to-valley data
„ 0: No peak-to-valley data
„ 1 – Rt: Peak-to-valley in [µm]
„ 2 – Ra: Mean peak-to-valley in [µm]
„ 3 – Rz: Mean peak-to-valley height in [µm]
„ 4 – Vr: Direct feed rate value in [mm/rev]
Peak-to-valley [ORW]
Peak-to-valley or feed-rate values
Permissible inward copying angle [EKW]
Tolerance angle for recess areas, used for distinguishing
turning from recessing (mtw = contour angle).
„ EKW > mtw: Relief turn
„ EKW <= mtw: Undefined recess (no form element)
