3-D compensation without TCPM

If the NC program includes surface normal vectors, the control
performs a 3-D compensation for three-axis machining. In this
case, the RL/RR radius compensation and TCPM or M128 must be
inactive. The control displaces the tool in the direction of the surface-
normal vectors by the total of the delta values (from the tool table
and TOOL CALL).
The control generally uses the defined delta values
for 3-D tool compensation. The entire tool radius R +
DR) is only taken into account if you have activated the
FUNCTION PROG PATH IS CONTOUR function.
