Specification of a new reference point for a coordinate system through
reference to an existing zero and a -> frame.
-> Work offset
1. Settable
SINUMERIK 840D: A parameterizable number of settable zero
offsets is available for each CNC axis. The offsets - which are
selected by means of G functions - take effect alternately.
2. External
All offsets which define the position of the workpiece zero can be
overlaid with an external zero offset
- defined by handwheel (DRF offset) or
- defined by the PLC.
3. Programmable
Zero offsets can be programmed for all path and positioning axes
by means of the TRANS instruction.
