Theoretical Cutting Force Prediction and Analysis of Boring Process Using Mathcad

Boring is a frequently employed finishing operation in machine shops. Boring is a process in which pre-drilled holes or holes in cast, forged or extruded components are enlarged or finished with a cutting tool mounted on a boring bar. The process is mostly used in applications where close dimensional tolerances and good surface finish are required. In this research work based on the theoretical cutting force model, values of force components have been obtained by using the combination of work piece and tool signature. The cutting forces are theoretically resolved in the tangential force (Ft), feed force (Ff), radial force (Fr) directions. The study of cutting forces of boring process is therefore a prerequisite for selecting appropriate cutting conditions. A predictive cutting force model has been developed and influence of cutting parameters on force components has been depicted as graphs using mathematical tool MathCAD 8 professional software.
