Abstract

Tool wear is an inevident phenomenon during the cutting process that can deteriorate the machined surface quality and lower cutting efficiency. The effects of tool wear on the machined surface quality can be classified into three aspects: increasing the surface roughness, generating form error, and affecting the surface finish. Also, the occurrence of tool wear can change the cutting force amplitude and chip morphology. Therefore, the tool wear information can be reflected by cutting force and chip morphology. However, information about tool wear is usually implicit and needs to be processed. This chapter provides an account of tool wear evaluation methods based on cutting forces. An analytic cutting force model and a dynamic model are established to simulate the cutting force pulse and the free vibration of dynamometer induced by the cutting force pulse. The relationship between cutting force and cutting parameters, such as the feed rate and depth of cut, is presented, and the power spectrum features of cutting forces at different tool wear stages are explored.
