On the Mechanics of the Grinding Process Under Plunge Cut Conditions

Abstract

Two broad categories of grinding action are recognized; one where negligible ploughing and rubbing take place and where the plunge velocity versus normal force intensity curve is a straight line through the origin, the other where ploughing and rubbing predominate and the plunge velocity versus normal force intensity curve is concave upward. The effects of wheelspeed, workspeed and conformity are found to differ depending upon which category the grinding action falls under. A theory relating the metal removal rate to the force intensity is presented which applies only to grinding with negligible rubbing and ploughing.
