Distribution over the geometry-axis components
How the three vector components of partial totals of the vectors involved are distributed over the three geometry-
axis components is determined by the following quantities:
The resulting tool orientation always remains parallel to one of the three axis directions X, Y or Z and exclusively
depends on the active machining plane
G17-G19
, since it has not yet been possible to assign the tool an
orientation.
Stepless variation of the tool orientation
The toolholder with orientation capability also enables the tool orientation to be varied steplessly, in addition to
providing further offsets or linear expansion fluctuations with the aid of offset vectors l

- l

.

Minor operator compensations
Minor compensations, however, must also be modified during the normal production mode.
The reasons for this are e.g.:
• Tool wear
• Clamping errors
• Temperature sensitivity of the machine:
These compensations are defined as follows:
Influencing quantity
