Comment
; Definition of leading and following axes,
; C is the slave axis for X and Y in the
; basic coordinate system
; Start position
; Activate coupled motion of rotatable
; tool axes C/C1
; C/C1 axis rotates to 225° → stroke
; C/C1 axis rotates to 45° → stroke
; C/C1 axis rotates to 90°, no
; stroke initiation
; Path segmentation: four strokes are performed
; with tool rotated to 90°
; Positioning
; Activate tangential control,
; offset angle of rotatable tool axes 180°
; Path segmentation, three strokes for active
; tangential control and an
; offset angle of 180°
; C/C1 rotates to 225° (180° + 45° INC),
; Tangential control deactivated because no
; path segmentation → stroke
; Tangential control without offset
; Path segmentation, three strokes for active
; Tangential control without offset angle
; Deactivate stroke initiation +
; Tangential control
; Activate coupled motion of rotatable
; tool axes C/C1
