B–63522EN/02
NC FUNCTION
328
This function allows program restart by specifying the desired sequence
number, for example after tool break and change, or when machining is
restarted after holidays. The NC memorizes the modal status from the
beginning of the program to the sequence number.
If there are M codes necessary to be output, output the M code by the MDI,
press the start button, the tool automatically moves to the start position,
and the program execution restarts.
These functions are used for replacing tools damaged retraction of tools
for confirming the cutting conditions, and recovering the tools efficiently
to restart the cutting.
Also, the escape operation can be performed with the tool retract signal
by previously setting the escape amount (position) with a program. This
can be used for retraction for detecting tool damage.
1 Input the tool retract signal during executing the automatic operation.
Then, the automatic operation is halted and the escape operation
(retraction) is performed to the escape position commanded by the
program.
2 Input the tool retract signal to initiate the retract mode.
3 After that, switch the automatic mode to the manual mode to move
tools with manual operation such as the jog feed and handle feed. A
maximum of 10 points can be automatically memorized as travel path.
4 Input the tool recovery signal to return the tool to the retraction
position in the opposite direction along the path moved by manual
operation automatically (recovery operation).
5 Perform the cycle start to return the tool to the position where the tool
retract signal was entered (repositioning). When the recovery
operation completes, the halted automatic operation resumes.
