Programming example
Machining sequence:
● Inching at position -100.0000 mm to Y position -20.0000 mm, old offset is deleted first
● The handwheel is used exclusively for the infeed.
● If an automatic infeed is selected, it will be implemented on a per-stroke basis.
● The start position is at -110.000 mm.
● The table feedrate is 30,000 mm/min between points -350 and 100 (450 oscillating path).
● Sparking-out strokes are performed when infeed is aborted.
● In the example below, which illustrates the next step, the sequence continues with a 3-
