23. AUTOMATIC OPERATION
NC FUNCTION
201
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.
In cases such as when tool movement along an axis is stopped by feed hold
during automatic operation so that manual intervention can be used to
replace the tool: When automatic operation is restarted, this function
returns the tool to the position where manual intervention was started.
To use the conventional program restart function and tool withdrawal and
return function, the switches on the operator’s panel must be used in
conjunction with the MDI keys. This function does not require such
operations.
During automatic operation, tool can be adjusted by the manual pulse
generator without changing the mode. The pulse from the manual pulse
generator is added to the automatic operation command and the tool is
moved for the recommended pulses.
The work coordinate system thereafter is shifted for the pulse commanded
value. Movement commanded by handle interruption can be displayed.
