Components processed by conventional micro-milling often cannot achieve the performance requirements especially for hard and brittle materials. Vibration assisted machining (VAM) can significantly reduce the cutting force, enhance the surface integrity and extend the tool life. This paper is focused on the tool-workpiece separation mechanism of vibration assisted micro milling (VAMM) through cutting simulation. Firstly, a finite element (FE) model of VAMM of hardened steel is established in ABAQUS. Secondly, three typical tool-workpiece separation types in VAMM are observed and discussed based on the simulation results. Finally, the cutting force and stress distribution are compared between the VAMM and conventional micro milling.
