Define the workpiece material in the NC program with the WMAT soft key.
The TOOL CALL block provides soft keys for automatic acceptance of various
speeds (S1 to S4) and for the selection of the feed rate.
If you enter the spindle speed manually, this value is taken into account in the
calculation of the feed rate. You cannot, however, enter F for calculation of S.
If you enter the feed rate manually, the entered value applies until you program
another feed rate. With the F AUTO soft key you can again activate the feed
rate from the TOOL CALL block.
Automatic tool identification is possible with the Balluff tool identification
system (BIS).
