Overview

The geometries of the machining tool must be taken into consideration when executing a part
program. These are stored as tool offset data in the tool list. Each time the tool is called, the
control considers the tool offset data.
When programming the part program, you only need to enter the workpiece dimensions from
the production drawing. The control then independently calculates the individual tool path.
Measuring grinding wheels and dressers
You determine the tool offset data, i.e. the lengths or the positions of the tools, by making
manual measurements (scratching).
When measuring manually, traverse the tool manually to a selected reference point in order
to determine the tool dimensions and positions in the X and Z directions. The control then
calculates the tool offset data from the position of the tool carrier reference point and the
approached reference point.
Measuring the reference points for the grinding wheel
For manual measurements of a grinding tool, you have the option of selecting the following
reference points:
● Workpiece (with zero offset)
● Dresser (with zero offset as dressing tool)

Press the "Delete all" softkey.
A confirmation prompt is displayed as to whether you really want to delete
the seat-related fine offsets.
Note:
The "Delete all" softkey is only available if seat-related work offsets have
been set up.
5. Press the "OK" softkey to confirm that you wish to delete the work offset.
