a steady feed rate along the grinding gap the workpiece has to be in simultaneous line contact with the grinding wheel, the regulating wheel and the work rest blade. This yields a noncylindrical shape of the inclined regulating wheel that leads to variations in workpiece speed, especially when grinding long work pieces [9].

The centerless grinding process is characterized by a particular workpiece (WP) holding system. The WP is supported on three points by the grinding wheel, the control wheel and the workrest, also called supporting blade (see Fig.1).This configuration makes the process prone to roundness errors, depending on the initial setup of the machine []: WP center can oscillate and create a polyhedral ...

In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds.One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear speed than the workpiece at the point of contact.
