Mode of action of the programmed feed rate
The TNC provides two functions for defining the mode of action of the
programmed feed rate:
 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.
 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:
...
13 FUNCTION TCPM F TCP ... Feed rate refers to the tool point
14 FUNCTION TCPM F CONT ... Feed rate is interpreted as the speed of the tool
along the contour
