Hi. Good morning for everybody

I have a problem with a milling machine.

We make different holes in a piece and, sometime, the rpm is stop when it is making any hole and after stopping continues without stopping the machine. The problem is that the operator don´t watch the problem and this hole is not good finished. Do you Know if there are a parameter or variable to controlate RPM if is lower than 100RPM for example stop the machine
