Chained transformations (TRACON, TRAFOOF)

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

parts from the second transformation act on the machine axes.

The chain may include two transformations.

A tool is always assigned to the first transformation in a chain. The subsequent

transformation then behaves as if the active tool length were zero. Only the basic tool

lengths set in the machine data (_BASE_TOOL_) are valid for the first transformation in the

Machine manufacturer

Take note of information provided by the machine manufacturer on any transformations

predefined by the machine data.

Transformations and chained transformations are options. The current catalog always

provides information about the availability of specific transformations in the chain in specific
