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.
