Abstract
PURPOSE: To automate emergency stop at the time of abnormality, by measuring the voltage which is generated between nozzles and a work or a grinding stone.
CONSTITUTION: Contact and non-contact of a grinding stone 1 are detected by the size of thermoelectromotive force which is generated between the first nozzle 4-1 electrically insulated with use of electric conductive grinding liquid and a work 2, voltage is applied between the second nozzle 5 electrically insulated likewise and the work 2, approaching distance between the both is detected by the size of its voltage, contact condition and minute grinding force which include loss of the grinding stone 1 are supervised by in-process without losing rigidity and workability of the machine itself, so that emergency stop at the time of abnormal machining can be automated.
