Hi
I have a Daewoo h63 machine tool with 18 Fanuc control system.
In normal mode, there is no movement with g01 when the spindle motor stops.
But when the gear shift shaft becomes defective and the mechanical connection between the spindle and the spindle motor is interrupted.
The spindle motor is rotating but the spindle is stopped.
Therefore, the machine tool does machining without rotating the spindle and causes the tool failure.
Why does the machine tool only notice the movement of the motor and does not give an alarm to stop the spindle?
