Type of machining for technology database access: Finishing
Cycle run
1 Move in transverse direction from the starting point to the contour
starting point X1, Z1
2 Finish defined contour area
3 Return to starting point on paraxial path
4 Move to the tool change point according to the G14 setting
Cut, transverse finishing plunge
Select cut, longitudinal/transverse
Select plunge, transverse
Press the Finishing run soft key
The cycle finishes the contour area from the contour starting point
to the contour end point. At the end of the cycle, the tool returns to
the starting point.
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
cycle (machine-dependent)
 Main drive
 Opposing spindle for rear-face machining
 The tool plunges with the maximum possible angle,
leaving material remaining.
 The steeper the tool plunges into the material, the
greater the feed rate decrease (max. 50 %).
