7.3.3 Workpiece Coordinate System Preset (G92.1)
The workpiece coordinate system with its zero position away by the
workpiece zero offset amount from the machine coordinate system zero
position is set by returning the tool to the reference point by a manual
operation. Also, when the absolute position detector is provided, the
workpiece coordinate system is automatically set by reading the
machine coordinate value from the detector when power on without
performing manual reference point return operation.
The set workpiece coordinate may shift by any of the following
commands or operation:
- When manual interruption is performed with the manual absolute
signal off
- When the travel command is performed by the machine lock
- When axis travel is performed by the handle interrupt or
auto/manual simultaneous operation
- When operation is performed by mirror image
- When the setting of local coordinate system is performed by the
G52 or change of workpiece coordinate system is performed by
the G92
The workpiece coordinate system shifted by the above operation can be
preset by the G code instruction or MDI operation the same as
conventional manual reference point return.
Format
G92.1 IP 0;
IP 0 ; Specifies axis addresses subject to the workpiece
coordinate system preset operation.
Axes that are not specified are not subject to the preset
operation.
Workpiece coordinate system preset by MDI operation
The workpiece coordinate system can be preset by the MDI operation
with soft keys.
