Selection of optimum conditions in centreless grinding is based on the roundness error and surface finish which are post-process measurements. In-process measurement of the roundness error and surface finish, because of its complexity, has hardly been attempted in centreless grinding. But monitoring of some of the process parameters during grinding can be done to control the quality of the ground parts. In this paper, the influence of some of the process parameters on the quality of the ground parts is brought out and how monitoring of these parameters can lead to the optimum conditions is discussed. Experimental work carried out in this connection is reported.

The geometrical features of the engineering components should maintain good form accuracy and proper relationship among them. This paper discusses the problems encountered in the measurement of relationship and explains the application of least squares technique with simple numerical examples. Evaluation of different errors on the component would be useful in controlling the manufacturing process and in understanding the functional aspects.
