Illustration of programming example in XY plane
; C/C1 axis rotates to 45° → stroke
; C/C1 axis rotates to 90° , no stroke initiation
; Path segmentation: four strokes are executed
with tool rotated to 90°
; Position
; Activate tangential control, offset angle of
rotatable tool axes 180°
; Path segmentation, three strokes with 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 with active
tangential control but without offset angle
; Deactivate stroke initiation + tangential
control
; Deactivate coupled motion of rotatable tool axes
