Design of a defined grain distribution brazed diamond grinding wheel for ultrasonic assisted grinding and experimental verification

In this paper, experiments are conducted to study the characters of Ultrasonic Assisted Grinding (UAG) and Conventional Grinding (CG), diamond grinding wheel is used in experiments, grinding forces and surface roughness are measured in both UAG and CG. The effects of different parameters on grinding force, surface roughness and force ratio are discussed. The results show that the grinding force and surface roughness in UAG is smaller than those in CG. The force ratio in UAG is lower than that in CG, which reveals that the grinding wheel has a good wear-resistant property in UAG process.

In this paper, topography feature of the diamond grinding wheel under the diamond stylus elliptical ultrasonic vibration assisted dressing was studied experimentally. The results indicate that: the increase in dressing power of elliptical ultrasonic vibration will result in the increase in amplitude, and that can increase abrasive protrusion height of the dressing grinding wheel, and also increase the depth of chip pocket. With the increase of feed rate, surface peak and valley values of elliptical ultrasonic vibration dressing grinding wheel increase, that is the average protrusion height of abrasive grain increases. With the increase of dressing depth, surface peak and valley values of elliptical ultrasonic vibration dressing grinding wheel increases, while the number of static effective abrasive grain reduces. In comparison with the ordinary dressing grinding wheel, elliptical ultrasonic assisted dressing in the same parameters can bring about more static effective abrasive grain , more uniform abrasive distribution, a higher abrasive protrusion height and more chip space.

A 3D profiler based on scanning white light interferometry with a lateral sampling interval of 0.11μm was introduced to measure the surface topography of a #3000 diamond grinding wheel, and a large sampling area could be achieved by its stitching capability without compromising its lateral or vertical resolution. The protrusion height distribution of diamond grains and the static effective grain density of the grinding wheel were derived, and the wheel chatter and the deformation of the wheel were analyzed as well. The study shows that the grain protrusion height obeys an approximate normal distribution, the static effective grain density is much lower than the theoretical density, and only a small number of diamond grains are effective in the grinding process with fine diamond grinding wheel. There exists waviness on the grinding wheel surface parallel with the wheel cutting direction. The cutting surface of the grinding wheel is not flat but umbilicate, which indicates that the elastic deformation at the wheel edges is much larger than in the center region.
