Optimization of Turning Tool Geometry by Nonlinear Programming

This paper deals with the determination of optimal tool geometry for longitudinal turning. A tool life is usually the main machinability factor and, as such, the basic optimization criterion of tool geometry. The establishing of tool response function is done by the second order central composite design of experiment. Since the criterion function is inherently nonlinear in this case, i.e. besides linear contains quadratic elements and two-factorial interactions, the care must be taken to employ an appropriate optimization method for solving such function. Therefore, the optimization procedure based on nonlinear programming methods is proposed. Furthermore, the testing example of developed algorithm is presented.
