Chained Transformations (Tracon, Trafoof) - Siemens Sinumerik 840D sl Programming Manual

6.12

Chained transformations (TRACON, TRAFOOF)

Function
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.
Note
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 chain.
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
controls.
Applications
• 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
inclined grinding wheel.
