摘要： Provided is a detecting method of abnormality of a machine tool operation, and the detecting method includes a preparing step S100; a reference waveform obtaining step S200 of measuring a drive voltage and a drive current, while machining the material in a normal state of the machine tool, and obtaining a reference waveform; a monitoring section setting step S300 of setting a monitoring section and thus automatically calculating a maximum load value and a minimum load value; a permissible limit setting step S400 of setting maximum and minimum permissible limits; and a monitoring step S500 of obtaining a machining load generated and determining whether a difference between maximum and minimum load values of the machining load is out of the maximum or minimum permissive limit and then outputting normality or abnormality thereof.
