9 Machining a Workpiece
Restart type 2
If a machining program differing from the machining program to be restarted was run before starting restart search, restart
with restart type 2.
When the coordinate system of the automatic operation last time and the coordinate system of the machining restart are
changed, it is possible to restart.
Note
(1) The necessary matters for starting the machining program, such as setting the coordinate system, must be completed
before starting restart search.
In the MDI mode, set the coordinate system to be
used when starting the program to be restarted.
Move each axis to the program start position.
Search for the block to be restarted.
(Refer to "Executing Restart Search (Restart type 2)")
Turn the program restart switch ON.
Execute the manual numerical value command
(S,M,T,B)
(Refer to "Executing the MSTB Commands")
In the manual (JOG/rapid traverse) mode, move
the axes to the restart return position.
(Refer to "Returning to the Restart Position")
Turn the program restart switch OFF.
Return to the automatic operation mode.
Press the cycle start button.
Note
(1) When single block signal is OFF, the machining is restarted without stopping temporarily after the axes return to the
restart position. (The cycle starts when the automatic return by program restart is valid.)
(2) Restart search is not available for a program that has a file name consisting 33 or more characters.
(3) When the searched program do not exist, the operation message "Search error" appears.

If the command at the head of the program is an
incremental command or G92 command, and none
of the axes are at the program start position, the
program does not restart properly.
Operation on program restart screen
The following items are displayed when restart
search is completed.
• Remaining distance when the restart search is
completed
• Restart position (on local coordinates)
• Each command value of the SMTB functions.
"RP" is displayed for the axes that have moved to
the restart position. After this, the axis does not
move in either the + or - direction.
If the cycle starts when the "Automatic return by
program restart" parameter ("#1302 AutoRP") is
ON, the processing is restarted after all axes return
to the restart position at the same time.
