Effect of the programmed feed rate
The control provides two functions for defining the effect 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.
