Depending on the selectedmachining plane, the angle refers to another axis. The direction in which a positive angle pointsalso depends on the machining plane.Machining plane Rotate Face PeripheralReference axis for angle Z X YPositive angle in direction of the axis X Y ZThe tool traverses a circular path from its actual position to the programmed end point (angle)at the machining feedrate. The radius is obtained from the distance between the actual toolposition and the defined pole, i.e. the circle start and end point positions are at the samedistance from the pole.The 1st arc in polar coordinates entered after the pole must be programmed in absolutedimensions. You can program any additional lines or arcs also in incremental dimensions.Programming technology functions (cycles)10.7 Additional cycles and functions in ShopTurnTurning584 Operating Manual, 05/2017, A5E40868721
