Cutting Speed and Feed Rate Optimization for Minimizing Production Time of Turning Process

Optimum selection of cutting conditions importantly contribute to the increase of productivity by minimization of production time and the associated costs, therefore utmost attention is paid to this problem in this contribution. Time is the most important parameter in any operation and all the manufacturing firms aim at producing a product in minimum time to reach the customer quickly and enhance the customer satisfaction. This can be achieved by using optimization techniques. The success of an optimization technique does not lie in its complexity but the time in which it provides a solution to the manufacturing firms. In this research paper, a geometric programming based approach to optimize the production time of the turning process within in some operating constraints is proposed. It involves mathematical modeling for production time of turning process, which is expressed as a function of the cutting parameters which include the cutting speed and feed rate. Then, the developed mathematical model was optimized with in some operating constraints like the maximum cutting speed, maximum feed rate, power constraint and the surface roughness constraint. The results of the model reveal that the proposed method provides a systematic and efficient technique to obtain the optimal cutting parameters that will minimize the production time of turning process. Thus, it is possible to optimize the production time of turning process effectively by geometric programming. The approach is suitable for fast determination of optimum cutting parameters during machining, where there is not enough time for deep analysis.
