Cycle run
1 Calculate the proportioning of cuts (infeed)
2 Approach the workpiece from starting point for first pass
3 Move at the programmed feed rate to the contour end point X2
4 The contour is machined depending on the contour smoothing H:
5 Retract and approach for next pass
6 Repeat 3 to 5 until the contour starting point Z1 is reached
7 Return to starting point on diagonal path
8 Move to the tool change point according to the G14 setting
MFS M at beginning: M function that is executed at the
beginning of the machining step
MFE M at end: M function that is executed at the end of the
machining step
WP Displays which workpiece spindle is used to process the
