Detection and compensation of cutting tool wear based on Lipschitz exponent

In this article, a new method is proposed for cutting tool wear detection and compensation based on Lipschitz exponent. In general, there are three phases in tool wear, namely, incipient, normal and dramatic phase. And there are different values of Lipschitz exponents of cutting force signal in different phases. So we can identify the different phases of cutting tool wear by comparing the values of lipschitz exponents in different phases of cuffing tool wear. If tool wear can be accurately identified, a good compensation strategy can be properly designed.
