Mode of action of the programmed feed rate
The TNC provides two functions for defining the mode of action of the
programmed feed rate:
U F TCP determines that the programmed feed rate is
interpreted as the actual relative velocity between the
tool point (Tool Center Point) and the workpiece.
U F CONT determines that the programmed feed rate is
interpreted as the contouring feed rate of the axis
programmed in the respective NC block.
Example NC blocks:
