7.3 TRAANG oblique angle transformation (option)
Comment
; XZ planes, tool selection, clamping compensation
; Activate TRAANG with the first TRAANG data set
and angle 45°
; Approach the start position
; Wait for end of travel of the Z axis
; Oscillating motion
; OSP1/OSP2: Left/right reversal point
; OST1/OST2: Stopping point at the left/right re-
versal point
; Activate oscillation
; Position X axis in parallel
; Deactivate oscillation
; Wait for end of travel of the Z axis
; Deactivate transformation
; Retract
M1: Kinematic transformation
