Abstract
In centreless through feed grinding the quality of the ground parts is influenced by several process variables. Some of these process parameters alter the frictional conditions at the control wheel-workpiece and the grinding wheel-workpiece interfaces which, in turn, influence the axial feed rate and rate of rotation of the workpiece. In addition, the type of cutting fluid plays an important role in determining the friction at the control wheelworkpiece interface. In this paper, an attempt is made to describe the influence of some of the process parameters on the slip in the axial movement and the change in the rate of rotation of the workpiece. Also the influence of different cutting fluids, which alters the nature of the frictional contact at the control wheel-workpiece interface, on the workpiece movements and quality of the ground parts is described. The experimental work carried out, in connection with this, is included. Further, from the analysis of the experimental results some useful conclusions have been derived which would be helpful in improving the performance of the process. © 1987.
