Abstract
An apparatus and method for measuring the electrical load on a motor driven tool operating in a cycle having idle and cutting or machining states. The electrical power is continuously measured and an average power value is established during the idle state of at least one cycle and used as an offset subtracted from the measured electrical power values to generate an output proportional to the incremental power drawn by the cutting tool during the cutting state. The offset value is recalculated at the start of each new cycle and/or just prior to the commencement of a cutting operation by a tool. At least one filter and/or an amplifier are used to improve the signal-to-noise ratio of the output signal.
