The Force in Single-Pass Scratch Tests at Variable Sliding Velocities
Abstract:
To investigate the characteristics of material removal mechanism in the continuous contour control grinding. It is simplified as a variable speed single grit scratching the surface of quench hardening AISI 5140 steel. Utilizing optical microscope, optical profiling system and displacement transducers, the scratch morphology and force were analyzed with applied normal load (depth) and scratch separation distance. Piles-up at the sides of the groove is no obvious change with traverse speed pulse. Both the normal force and the tangential force increase with an increase in traverse speed and depth. The change of traverse speed leads to force fluctuating, and then the forces fall down rapidly to a constant value relatively.
