Depending on the selectedmachining plane, the angle refers to another axis. The direction in which a positive anglepoints also 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 theactual tool position and the defined pole, i.e. the circle start and end point positions are at thesame distance 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.
