A mechanistic model is developed for RUM end surface grinding of CFRP composites with elliptical ultrasonic vibration. • The interaction between the abrasive grain and workpiece is intermittent. • The tool-workpiece contacting area is analyzed. • The effective cutting time in one ultrasonic cycle is calculated. •

A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.

Shaping is a process of machining a flat surface which may be horizontal, vertical, inclined, concave, or convex using a reciprocating single point tool. A shaping machine is a reciprocating type of machine tool. The work is held firmly on the table and the ram is allowed to reciprocate over it. A single point cutting tool is attached to the ram.
