Woodruff School of Mechanical Engineering, Georgia Institute of Technology, Atlanta, Georgia, USA; and 2Advanced Manufacturing Technology Development, Ford Motor Company, 24500 Glendale Avenue, Detroit, USA This paper describes the development of an analytical model effect of factors such as tool wear [3], cutter runout [4–6], for the cutting forces in multiblade plunge cutting of cylindrical cutter tilt [7], and system compliance [8–10]. parts. The development uses the relationship between the Plunge cutting with multiple blades with different geometri- instantaneous chip area and the local cutting forces at each cal attributes is widely used to create complicated chamfer individual blade to formulate the total resultant forces via patterns on cylindrical parts. One example application of this kinematic integration along the cutting edges. The model process is the shaping of valve seats for internal combustion expresses the cutting forces in explicit terms of part material engines, an operation which typically requires a number of properties, cutter geometry, part geometry, and cutting con- chamfers to be machined with significant precision and through- ditions. Experiments were performed under various cutting put. The understanding of cutting force characteristics is critical conditions to verify the fidelity of the model at different stages to the optimisation, monitoring, a
