Cylinder surface transformation (TRACYL)

The TRACYL cylinder surface transformation function can be used to:

• 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

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)
