11.4.2 Automatic Operation Handle Interruption
M720VW
M system ○
L system ○
The handle command can interrupt and be superimposed onto a command without suspending automatic
operation and the machine can be moved by rotating the manual pulse generator during automatic
operation.
If the spindle load is greatly exceeded when cutting a workpiece as per the machining program due to a high
rough cutting amount in face machining, for instance, automatic handle interrupt makes it possible to raise
the Z surface and reduce the load easily without suspending feed in the automatic operation mode.
Automatic handle interrupt is conducted by setting the "automatic handle interrupt" valid switch which is
provided separately from the "manual operation mode". The axis selection, pulse scale factor and operation
are conducted as for manual handle feed.
Whether, after an interrupt, to return to the path of the machining program by automatic operation or remain
offset by the amount equivalent to the interrupt amount is determined using a parameter.
