Arc approximation

This command enables you to create G2/G3 GCode output from Contour rough operations. SolidCAM checks whether successive points of the calculated tool path can be connected using an arc or a circle. If arc or circle connection within the specified arc approximation tolerance can be made, you receive arc and circle interpolation commands G2 and G3 in the generated GCode.

This feature can drastically reduce the number of lines in GCode files. Most CNC-controllers and machines work much faster on arcs and circles than on single tool path points or splines.  Arc approximation will increase actual feed rates on older CNC-machines and the machine will work smoother.

The Tolerance value defines the tolerance SolidCAM uses to position tool path points on arcs or circles.

The arc approximation value should be smaller than the specified value for the surface offset. A warning message is displayed if a larger value could cause gouging of the model.
