Simulation and Experiment for Micro-surface Topography in Pre-stressed Dry Grinding Process
To study effect mechanism of pre-stress on surface micro-topography, single grain grinding simulations are carried out in DEFORM-3D, besides, dry grinding experiments are conducted.The residual stress, groove depth and pile-up deformation are analyzed in simulations, and surface roughness is measured in experiments.The results indicated that application ofpre-stress is beneficial to generate more compressive stress, which is beneficial to restrain the generation of surface micro-cracks.Pre-stress can reduce the height of pile-up deformation.When pre-stress is within a lower range, groove depth decreases with pre-stress increasing, however, once pre-stress overcomes a certain value, surface fold appears and surface roughness increases instead.
