A method and apparatus for monitoring the condition of a tool or a workpiece includes an electromagnetic energy source for directing electromagnetic energy toward the tool and also receives electromagnetic energy reflected off the tool. A detector is arranged to receive the reflected electromagnetic energy from the electromagnetic energy source and converts the reflected energy into electronic signals. The electronic signals are transmitted from the detector to a control signal generator and then to a signal analyzing device. The signal analyzing device compares the electronic signals received from the control signal generator to reference signals to determine the condition of the tool or workpiece. Then, the control signal generator generates a control signal based on the result of the comparison performed by the signal analyzing device and transmits the control signal to a tool controlling device controlling the operation of the tool.
