2.8.4 Simple workpiece stock removal
Some blanks do not have a smooth or even surface. Use the stock removal
cycle in order to face the front surface of the workpiece before the
actual machining.
The prerequisite for the simple stock removal of a workpiece in
manual mode is that a tool with known measurements is in the
machining position (see Sec. "Selecting a Tool and Spindle").
If you want to turn out a collet using the stock removal cycle, you can
program an undercut (XF2) in the corner.
Caution
The tool moves along a direct path to the start point of the stock
removal. First move the tool to a safe position in order to avoid
collisions during the approach.
You cannot use the "Repos" function during simple stock removal.
Jog
 Select the "Stock removal" softkey in "Machine Manual" mode.
 Enter values for the parameters.
