Parameter Description UnitL Distance to the pole, end point mmα Polar angle to the pole, end point (abs) orchange in polar angle to the pole, end point (inc)DegreesF Machining feedrate mm/revmm/minmm/toothRadius compensation Input defining which side of the contour the cutter travels in the programmed direc‐tion:Radius compensation to left of contourRadius compensation to right of contourRadius compensation offThe set radius compensation remains as previously set10.7.14 Circle polarA circle in the polar coordinate system is defined by an angle (α). 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 actual tool positionto the defined pole, i.e. the circle starting and end point positions are at the same distancefrom 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.
