ASM
Other options:
● A tool center offset relative to the turning center is permitted.
● The tool center point path can pass through the turning center point of the rotary axis.
● The rotary axis does not need to be a modulo axis.
Note
For active transformation, the names of the involved machine, channel and geometry axes are
different:
● MD10000 $MN_AXCONF_MACHAX_NAME_TAB (machine axis name)
● MD20080 $MC_AXCONF_CHANAX_NAME_TAB (channel axis name)
● MD20060 $MC_AXCONF_GEOAX_NAME_TAB (geometry axis name)
7.1.1.2

Machining options

The TRANSMIT transformation has a pole at the zero point of the TRANSMIT plane. The pole
is at the intersection of the radial linear axis and the rotary axis. In the vicinity of the pole, small
positional changes in the geometry axes generally result in large changes in position in the
machine rotary axis. The only exceptions are linear motions into or through the pole.
A tool center point path through the pole does not cause the parts program to be aborted.
There are no restrictions with respect to programmable traversing commands or active tool
