Glossary
Workpiece
Part to be made/machined by the machine tool.
Workpiece contour
Set contour of the → workpiece to be created or machined.
Workpiece coordinate system
The workpiece coordinate system has its starting point in the → workpiece zero-point. In
machining operations programmed in the workpiece coordinate system, the dimensions and
directions refer to this system.
Workpiece zero
The workpiece zero is the starting point for the → workpiece coordinate system. It is defined
in terms of distances to the → machine zero.
Zero offset
Specifies a new reference point for a coordinate system through reference to an existing
zero point and a → frame.
1. Settable
2. External
3. Programmable
940
A configurable number of settable zero offsets are available for each CNC axis. The
offsets - which are selected by means of G functions - take effect alternatively.
In addition to all the offsets which define the position of the workpiece zero, an external
zero offset can be overridden by means of the handwheel (DRF offset) or from the PLC.
Zero offsets can be programmed for all path and positioning axes using the
statement.
