Mode of action of the programmed feed rate

The control provides two functions for defining the operating
method of the programmed feed rate:
F TCP determines that the programmed feed
rate is interpreted as the actual relative velocity
between the tool tip (tool center point) and the
workpiece
F CONT determines that the programmed feed
rate is interpreted as the contouring feed rate
of the axes programmed in the respective NC
block.
