Kinematic transformations
TRANSMIT and TRACYL
For milling on turning machines, either
1. Face machining in the turning clamp with TRANSMIT or
2. Machining of grooves with any path on cylindrical bodies with TRACYL
can be programmed for the transformation declared.
TRAANG
If the option of setting the infeed axis for inclined infeed is required (for grinding technology,
for example), TRAANG can be used to program a configurable angle for the transformation
declared.
Cartesian PTP travel
Kinematic transformation also includes the so-called "Cartesian PTP travel" for which up to
8 different articulated joint positions STAT= can be programmed. Although the positions are
programmed in a Cartesian coordinate system, the movement of the machine occurs in the
machine coordinates.

Chained transformations
Two transformations can be switched one after the other. For the second transformation
chained here, the motion parts for the axes are taken from the first transformation.
The first transformation can be:
• orientation transformation TRAORI
• polar transformation TRANSMIT
• cylinder transformation TRACYL
• inclined axis transformation TRAANG
The second transformation must be a TRAANG type transformation for an inclined axis.
