It is interesting what hitting the Emergency stop will do, if too heavy a cut is going to damage the spindle then killing power would probably be ok, but if someone has a hand trapped then that is not the best option.
I worked on japanese grinding machines where all end of travel prox switches and the emergency stops were wired into the omron c500 machine controller. If the emergency stop button was pressed, the spindle would turn off, the table would retract in case someone was trapped, then power would go off turning off hydraulics and all power.
