Cylinder surface transformation (TRACYL)

Function
The TRACYL command activates the transformation to machine grooves 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 transformation:
●
●
●
For cylinder surface 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).
