3.6 Linear or circular path motions
The tool travels along a circular path from its current position to the
programmed circle end point. You must know the position of the circle
center point. The control calculates the radius of the circle/arc on the
basis of your interpolation parameter settings.
The circle can only be traversed at machining feedrate. You must
program a tool before the circle can be traversed.
Press the "Straight/Circle" and "Circle center point" softkeys.
