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.
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.
