If a machining cycle being executed is interrupted by a reset or emergency
stop at (X), the retreat program is called and executed with a workpiece
number search or program number search capability. For information
about the workpiece number search and program number search
capabilities, refer to the relevant manual published by the machine tool
builder. In the retreat program, specify a return operation by referencing
stored macro variables as required.
The start point of block (B) of N7010 is stored as the machining start point
in a macro variable, and the start point of block (I) of N8020 is stored as
the machining cycle start point in a macro variable.
M101 in block (B) of N7010 is stored as the machining type M code in
a macro variable. By using this macro variable, a machining cycle can be
determined so that the return cycle operation matching the machining
cycle can be performed. For rigid tapping, a G code for rigid tapping
return specification is available.
If a machining cycle being executed is interrupted by a reset or emergency
stop at (X), machining can be restarted at machining start point (B) after
starting the machining retreat program. In this case, use the following
sequence:
1. Return the tool to machining start point (B) with the retreat program.
2. Press the
RESET
key.
3. Select the restart of machining at the machining start point with the
machining restart point select switch.
4. Set the program restart switch to on.
5. Set the machining restart switch to on.
Thus, search operation is performed by virtually executing the programs
from the start of program number 1000 to machining start sequence
number 7010 stored in macro variables. Upon completion of search
operation, the machining retry completion lamp is turned on.
Then, by pressing the cycle start button, machining is restarted from block
(B).
