M1: Kinematic transformation
6.2 TRANSMIT face end transformation (option)
Transformation selection in pole
If the machining operation must continue from a position on the tool center path which
corresponds to the pole of the activated transformation, then an exit from the pole is
specified for the new transformation.
If
MD24911 $MC_TRANSMIT_POLE_SIDE_FIX_1 = 0
or
MD24951 $MC_TRANSMIT_POLE_SIDE_FIX_2 = 0
is set (pole transition), then a rotation as small as possible is generated at the beginning of
the block originating in the pole. Depending on this rotation, the axis then traverses either in
front of or behind the turning center.
For
MD24911 $MC_TRANSMIT_POLE_SIDE_FIX_1 = 1
or
MD24951 $MC_TRANSMIT_POLE_SIDE_FIX_2 = 1
machining is done before the rotational center point (linear axis in positive traversing range),
for
MD24911 $MC_TRANSMIT_POLE_SIDE_FIX_1 = 2
or
MD24951 $MC_TRANSMIT_POLE_SIDE_FIX_2 = 2
behind the rotational center point (linear axis in negative traversing range).
Transformation selection outside pole
The control system moves the axes involved in the transformation without evaluating
machine data MD24911 $MC_TRANSMIT_POLE_SIDE_FIX_t. In this case, t = 1 stands for
the first and t = 2 for the second TRANSMIT transformation in the channel.
