Repositioning Axes - Siemens SINUMERIK Series Operating Manual

6.6

Repositioning axes

After a program interruption in the automatic mode (e.g. after a tool breaks), you can move
the tool away from the contour in manual mode.
The coordinates of the interrupt position will be saved. The distances traversed in manual
mode are displayed in the actual value window. This path difference is called "Repos-offset".
Resuming program execution
Using the "Repos" function, you return the tool to the contour in order to continue executing
the program.
The interrupt position is not passed as it is blocked by the control system.
The feedrate/rapid traverse override is in effect.
NOTICE
Risk of collision
When repositioning, the axes move with the programmed feedrate and linear interpolation,
i.e. in a straight line from the current position to the interrupt point. Therefore, you must first
move the axes to a safe position in order to avoid collisions.
If you do not use the "Repos" function and subsequently move the axes in manual mode after
a program interrupt, the control automatically moves the axes during the switch to automatic
mode and the subsequent start of the machining process in a straight line back to the point
of interruption.
Precondition
The following prerequisites must be met when repositioning the axes:
● The program execution was interrupted using <CYCLE STOP>.
● The axes were moved from the interrupt point to another position in manual mode.

1. Press the <REPOS> key.
2. Select the axes to be traversed one after the other.
3. Press the <+> or <-> key for the relevant direction.
The axes are moved to the interrupt position.
