Abstract

The possibility of modeling the cutting forces provides an analytical basis for the planning of the machining process, for the construction of machine tool, the optimization of cutting tool geometry as well as on-line monitoring and process management. The planning and execution of the experiment was carried out on the basis of the rotatable central composite design-RCCD here for the input independent parameters the cutting speed was selected, i.e. the spindle speed (n), the feed per tooth (fz), the axial (ap) and radial (ae) depth of cut. Cutting forces (Fx,Fy,Fz) and the resultant cutting force (FR) for the responsive variables are selected. Using the RSM methodology, reliable mathematical models for cutting forces in the form of quadratic polynomials were obtained.
