Introduction

Two transformations can be chained so that the motion components for the axes from the first
transformation are used as input data for the chained second transformation. The motion
components from the second transformation act on the machine axes.
Conditions
● The chain normally consists of two transformations.
Exception: For testing purposes, it is permissible to enter only one transformation in the
chaining list.
● The first transformation can be:
– Orientation transformations (TRAORI), incl. universal milling head
– TRANSMIT
– TRACYL
– TRAANG
● The second transformation must be "Inclined axis" (TRAANG).
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)
Applications
The following is a selection from the range of possible chained transformations:
● Grinding contours that are programmed as a side line of a cylinder (TRACYL) using an
inclined grinding wheel, for example, tool grinding.
● Finish cutting of a contour that is not round and was generated with TRANSMIT using an
inclined grinding wheel.
