Finite element simulation of micro cutting process of ultrasonic assisted magnetic abrasive finishing

According to the relevant theory of metal cutting of finite element analysis, the finite element model of micro cutting process is established with titanium alloy Ti6Al4V to study the ultrasonic assisted magnetic abrasive finishing (UAMAF). The distribution and variation of stress and temperature field and chip formation are analysed. The results show that the stress and temperature of the contact area increase with the indentation depth, and the temperature and stress reach maximum when the indentation depth reaches the maximum. Meanwhile, the thickness and width of undeformed chip increase with the indentation depth.
