This paper is dedicated to the nanoscale machining simulation with the help of SPH method. The main goal of the research is to investigate the ductile mode machining of the brittle materials. The special scalar plasticity measure is introduced as a generic parameter of surface quality after machining. This measure can be used to describe the surface quality due to different machining modes and to...
A study was undertaken to investigate the wear characteristics of polycrystalline cubic boron nitride (PCBN) cutting tools and surface integrity during machining of STAVAX (specialised stainless steel) with and without coolant. Plastic deformation and formation of overtempered martensite and white layer (untempered martensite) were the dominant subsurface and surface defects. It was found that decreasing...
