Introduction

For a concatenated transformation, two transformations can be connected one after the other
(chained). As a consequence, motion components of the axes can be taken from the first
transformation and used as input data for the second transformation. The motion components
of the axes from the second transformation then act on the machine axes.
● The following are possible as first transformation:
– TRAORI orientation transformations, including universal milling head
– Face end transformation TRANSMIT
– Cylinder surface transformation TRACYL
● Only the following is possible as second transformation:
– Inclined axis TRAANG
Note
Exception, when commissioning
A concatenated transformation normally comprises two transformations chained one after the
other. For test purposes, e.g. during commissioning, it is also permissible to enter just one
transformation in the chaining list.
Note
Different axis identifiers
For active transformation, the names of the machine, channel and geometry axes involved
must be 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)
Application examples
● Grinding contours that are programmed as a side line of a cylinder (TRACYL) using an
inclined grinding wheel, e.g. tool grinding.
● Finish cutting of a contour that is not round and was generated with TRANSMIT using an
inclined grinding wheel.
