Cylinder Surface Transformation (Tracyl) - Siemens SINUMERIK 840D sl Programming Manual

Transformations
6.8 Kinematic transformation
Description
Pole
There are two ways of passing through the pole:
● Traversal along linear axis
● Traverse to the pole, rotate the rotary axis at the pole and traveling away from the pole
Make the selection using MD 24911 and 24951.
TRANSMIT with additional Y linear axis (transformation type 257):
This transformation variant of the polar transformation makes use of the redundancy for a
machine with another linear axis in order to perform an improved tool compensation. The
following conditions then apply to the second linear axis:
● A smaller working area and
● The second linear axis should not be used for the retraction of the parts program.
Certain machine data settings are assumed for the parts program and the assignment of the
corresponding axes in the BCS or MCS, see

6.8.2

Cylinder surface transformation (TRACYL)

Function
The TRACYL cylinder surface transformation function can be used to:
Machine
● longitudinal grooves on cylindrical bodies,
● Transverse grooves on cylindrical objects,
● grooves with any path on cylindrical bodies.
The path of the grooves is programmed with reference to the unwrapped, level surface of the
cylinder.
