Optimization of Multi-Pass Turning Operations

The selection of machining parameters in any machining process significantly affects production rate:quality and cost of a component. The present work involves the application of a newly developed global optimization technique called Differential evolution to optimize the machining parameters of multi-pass turning process. The optimal values of machining parameters such as number of passes, depth of cut in each pass, speed and feed are determined that correspond to the minimum total production cost subject to the technological constraints of allowable speed and feed, surface finish, maximum cutting force and maximum cutting power of the machine tool. An example is taken from the literature to illustrate the proposed procedure.
