The angle refers to the Xaxis.The tool moves from its actual position on a circular path to the programmed end point(angle) at the machining feedrate. The radius corresponds to the distance from the actualtool position to the defined pole, i.e. the circle starting and end point positions are at thesame distance from the defined pole.The 1st arc in polar coordinates entered after the pole must be programmed with an absoluteangle. You can program any additional straight lines or circles with incremental coordinates.Procedure1. The ShopMill program to be edited has been created and you are in theeditor.2. Press the menu forward key and the "Straight Circle" softkey.3. Press the "Polar" and "Circle polar" softkeys.Parameter Description UnitThe tool travels in the programmed direction from the circle starting point to its endpoint. You can program this direction as clockwise (right) or counter-clockwise(left).Clockwise direction of rotationDirection of rotationCounter-clockwise direction of rotationPolar angle to the pole, end point (abs) orchange in polar angle to the pole, end point (inc)DegreesF Machining feedrate mm/revmm/minmm/tooth
