Cylinder Surface Transformation (Tracyl) - Siemens SINUMERIK 808D ADVANCED Programming And Operating Manual

Description
Pole
There are two ways of passing through the pole:
● Traverse the linear axis alone
● Traverse to the pole, rotate the rotary axis at the pole and traveling away from the pole
Make the selection using MD 24911 and 24951.
Information
The turning center with X0/Y0 is designated as the pole. Workpiece machining operations close to the pole are not
recommended since these may require sharp feedrate reductions to prevent overloading of the rotary axis. Avoid selecting
TRANSMIT when the tool is positioned exactly on the pole. Ensure that the path of the tool center point does not travel
through the X0/Y0 pole.

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 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.
● If the machine has a real machine Y-axis(YM), an expanded TRACYL variant can also be configured. This allows
grooves with groove wall offset to be produced: the groove wall and base are perpendicular to each other - even if the
milling tool's diameter is smaller than the groove width. This is otherwise only possible with exact fitting milling cutters.
