4.4.4 REPOS (repositioning)
Function
After a program interruption in Automatic mode (e.g., to take a
measurement on the workpiece or to compensate tool wear values or
after tool breakage), you can retract the tool manually from the
contour after selecting "JOG" mode. In such cases, the control stores
the coordinates of the point of interruption and displays the path
distances traversed by the axes in "JOG" mode as a "Repos" offset in
the actual value window.
"Repos" offsets can be displayed in the machine coordinate system
(MCS) or workpiece coordinate system (WCS).
Sequence of operations
"JOG" mode is selected in the "Machine" operating area.
The axes have been moved away from the point of interruption.
