The intermittent nature of cutting in 1D VAM with the unique characteristic of elastic recovery is a very different machining process than CM. In this research, the chip formation in 1D VAM, which reveals the mechanism of the cutting process has been studied by Finite Element (FE) simulation to investigate the state of deformation of the chip followed by experimental analysis on a variety of metals with a set of parameters. The cutting experiments include both low-frequency and ultrasonic 1D VAM to investigate the chip formation, the forces, and the corresponding machined surfaces. It has been found from both FE simulation and experimental results that the intermittent cutting with elastic recovery and strain hardening facilitate the increased shear angle and smaller chip thickness in 1D VAM than CM. The smaller tool-chip contact length is also responsible for smaller chip thickness in 1D VAM than CM.","claims":[{"public_id":"cl_8bdf2a7b9a534816f0a477e33e23c3a0","status":"active","text":"A smaller
