9 Machining a Workpiece
9.3 Restart Search
Monitr
Reserch
With this function, the program search can be executed while updating the coordinate values and the modal information in
the same manner as an actual program operation.
Therefore, this function enables machining from a block in the middle of the program as if the actual machining was carried
out from the beginning.
This function is used to restart machining when a machining program is to be resumed after it has been suspended midway
due to tool damage or for some other reason.
The device [Memory card] and [USB Memory] are not selectable with this function.
There are two types of restart, type 1 and type 2.
Restart method
Restart type 1
Restart type 2
The validity of the automatic top search can be changed with control parameter "#8914 Auto Top search".
After machining is reset due to a tool breakage, etc., machining is restarted from the desig-
nated sequence number and/or block number.
Only the program which had been executed just before can be restarted.
Even after the power is turned ON again, the program can be restarted if the program has
been executed before the power supply is turned OFF.
<Note>
In case that NC has been reset or the power supply has been turned OFF while fixed cy-
cle, custom fixed cycle, MTB macro, or macro interruption is executed, the search with
no input to the setting will be performed for each source program.
When the user macro is executed, the user macro execution position is searched.
If a machining program different from the machining program to be restarted was run before
starting restart search, specify the sequence No. and block No. before restarting the machin-
ing.
Automatic top
A top search must be executed from the screen. Then, command a se-
search OFF
quence No. and block No., and restart a program.
Automatic top
A top search may not be executed from the screen. A top search is au-
search ON
tomatically executed, so it is not necessary to execute a top search from
the screen. Command a sequence No. and block No., and restart a ma-
chining.
An arbitrary program can be restarted by designating the program No.
When a program No. is omitted, the program currently searched is re-
started.
