Undeformed Chip Shape in Angular Grinding

Nakajima Toshikatsu

This paper describes the basic boundary conditions in angular grinding, which is widely applied as a high efficiency machining and where a complicated-shaped workpiece is ground at the same time. The angular grinding is first classified into three basic types, an external, a surface and an internal angular grinding, depending on the axis angle between the wheel and the work axes. The undeformed chip shape, which is characterized by the interference angle, the maximum chip thicknes and the chip length, is then analyzed in each type of angular grinding. The effects of grinding conditions such as the axis angle, the speed ratio, the radius ratio and the successive cutting edge spacing upon the geometry of undeformed chip are discussed to make clear the relations between the basic boundary conditions and the working conditions in angular grinding.
