General programming

The basic programming procedure is as follows:
1. Select work offset for cylinder surface transformation (e.g. offset the zero point on the
2. Position the Y axis (Y axis must be positioned prior to cylinder surface transformation
3. Activate cylinder surface transformation
4. Select work offset for machining on the developed cylinder surface (e.g. shift zero point to
5. Program machining operation (e.g. enter contour and path milling)
6. Deactivate cylinder surface transformation
The programmed cylinder surface transformation is simulated only as developed peripheral
surface.
Note
The work offsets active prior to selection of cylinder surface transformation are no longer
active after the function has been deselected.
Parameters
Cylinder surface trans.
Transformation number Selects the Tracyl data set, if there are several Tracyl data sets.

1. The ShopMill program to be edited has been created and you are in the
editor.
2. Press the "Various" softkey.
3. Press the "Transformations" and "Cylinder surface" softkeys.
Description
Yes
•
Activates the cylinder surface transformation for programming.
For several rotary axes, instead of "yes", the name of the rotary axis (A or B) is
displayed.
No
•
Deactivates cylinder surface transformation after programming.
Cylinder diameter - only for "Cylinder surface transformation yes"
