A method to increase material removal rate in tangential-feed centerless grinding performed on surface grinder

Abstract

In our previous study, a new centerless grinding method using surface grinder was proposed. However, the material removal rate was very small owing to the low worktable feed rate. This paper describes a practical method for increasing removal rate while workpiece roundness is maintained at a high level. In this method, the worktable feed rate is adapted appropriately so that the wheel depth of cut is kept constant during grinding. The actual grinding experimental results showed that the same level of workpiece roundness can be achieved only with a half of grinding cycle time once the worktable feed rate is adapted appropriately instead of the constant feed rate during grinding.
