Cylinder surface transformation (TRACYL)

Functionality
● 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.
● The control system transforms the programmed traversing movements in the Cartesian
coordinate X, Y, Z system into the traversing movements of the real machine axes. The main
spindle functions here as the machine rotary axis.
● TRACYL must be configured using special machine data. The rotary axis position at
which the value Y=0 is also defined here.
TRACYL transformation types
There are three forms of cylinder surface coordinate transformation:
● TRACYL without groove wall offset (TRAFO_TYPE_n=512)
● TRACYL with groove wall offset: (TRAFO_TYPE_n=513)
● TRACYL with additional linear axis and groove wall offset: (TRAFO_TYPE_n=514)
The groove wall offset is parameterized with TRACYL using the third parameter.
For cylinder peripheral curve transformation with groove side compensation, the axis used for compensation should be
positioned at zero (y=0), so that the groove centric to the programmed groove center line is finished.
Axis utilization
The following axes cannot be used as a positioning axis or a reciprocating axis:
● The geometry axis in the peripheral direction of the cylinder peripheral surface (Y axis)
● The additional linear axis for groove side compensation (Z axis).
