Studies on Grinding Action of the Diamond Wheel (Part 2)

Roughness of the Ground Surface

Abstract

As a part of the studies on grinding action of the diamond wheel where plunge cut method by plain cup wheels of bronze bonded was employed, we in this paper discuss some theoretical and experimental investigations on the roughness of ground surfaces.
Assuming that grinding tips are distributed at random in the wheel, the theoretical formulae representing H_max and roughness distribution curves were derived in the case of the wheel having conical or spherical grinding tips. And it was shown experimentally that H_max decreased with increasing of the diamond concentration, or with decreasing of the grain diameter used for the wheel. Though the theory agreed with the experimental results to some extent, it was recognized that the falling off of the abrasive grains out of the wheel surface is an important factor of formation of the ground surface in practice.
