Incremental programming (IC, G91)
Example for positioning axis: POS[axis name] = IC(+/-value)
● The value identifies the rotary-axis traversing distance. The value can be negative and
● The value's sign unequivocally defines the rotary-axis traversing direction.
● Application example: milling a spiral groove across several revolutions
