The Effects Of Grinding Process Parameters Of A Cemented

In the forming grinding of a cemented carbide microdrill, edge burrs are generated. to explore the formation of the edge burrs, the grinding parameters, such as feed rate, grinding depth, wheel service time, and wheel rotation, are analyzed experimentally. results show that the burrs on the microdrill edge are caused by material plastic flow and cumulative effect of deformation under the.
