Kinematic Transformation (M1)
Brief description

TRACYL

The cylinder generated surface curve transformation TRACYL allows the following:
Machining of
● Longitudinal grooves on cylindrical bodies,
● Transverse grooves on cylindrical bodies
● Arbitrary groove patterns on cylindrical objects.
The path of the grooves is programmed with reference to the unwrapped, level surface of the
cylinder.
For machining purposes, the function supports lathes with
● X-C-Z kinematics and
● X-Y-Z-C kinematics.
● The control transforms the programmed traversing movements of the cylinder coordinate
● For groove side offset, X-Y-Z-C kinematics is required with the following axes
506
system into the traversing movements of the real machine axes (standard applications X-
C-Z kinematics TRAFO_TYPE_n = 512):
– Rotary axis (1)
– Infeed axis perpendicular to axis of rotation (2)
– Longitudinal axis in parallel to axis of rotation (3)
Note
Linear axes (2) and (3) are perpendicular to one another. The infeed axis (2)
intersects the rotary axis. This constellation does not permit groove side offset.
(TRAFO_TYPE_n = 513):
– Rotary axis (1)
– Infeed axis perpendicular to axis of rotation (2)
– Longitudinal axis in parallel to axis of rotation (3)
– Longitudinal axis (4) to supplement (2) and (3) to obtain a right-hand cartesian
coordinate system.
Note
Linear axes (2), (3) and (4) are perpendicular to one another. This constellation
permits groove wall corrections.
