A new regulating wheel truing method for through-feed centerless grinding is presented. In conventional regulating wheel truing systems, a single-point diamond tool is traversed across the regulating wheel in a straight line. The interference between the regulating wheel and workpiece exists. This interference problem, a main source of error in precision through-feed centerless grinding, is due to the radius of curvature of the regulating wheel and workpiece. A new concept for regulating wheel truing is developed to eliminate the interference problem. In this new truing system, the rotary diamond truing tool has the same size as the finished workpiece, locates at the same center-height of the workpiece, and moves across the regulating wheel in the direction parallel to axes of workpiece and grinding wheel. A mathematical model is developed to calculate the surface profile for the regulating contact and to study the curved line of contact between workpiece and regulating wheel. An example is used to illustrate the model and to demonstrate that the interference between regulating wheel and workpiece has been eliminated.
