A machine tool monitor having a machine power sensor and a machine vibration sensor transmitting respective vibration and power signals to a controller which process the signals and monitors the machines operation to detect a change in the machine's processing parameters solely as a function of the power and vibration signals. The monitor indicates whether the condition of the tool and its associated machining operation warrants scrutiny or should be stopped for service. Besides visual and audible alarm signals the machining condition monitor can be integrated with an automatic control such as an NC controller or PC. In one embodiment a grinding machine monitor is provided with a power sensor and vibration sensor wherein the controller is adjusted to signal conditions associated with wheel sharpness, loss of coolant, and excessive vibrations.
