Abstract
The machining processes model is commonly used by manufacturing industries in order to produce precision component and very intricate products in a short time. These machining processes model include large number of process parameters which may affect the quality and cost of the components. Optimum machining parameters Selection in such machining processes is very significant to satisfy all the contradictory objectives of the process. There are two ways to select the optimal cutting parameters for a given financial objective. The primary one is apprehensive with the need of a machine expert that manually chooses the machining parameters on the basis of its own skill and by means of a proper machining handbook. That way creates many worries and drawbacks in terms of efficiency of solutions and cost / time requirements. As a substitute to the above mentioned approach, many research efforts have been done to state a pervasive mathematical model of a turning process that, in practice, mentions a set of cutting constraints to be handled. Machining optimization problems become delicate whenever a given objective function must be optimized in accordance to a large number of constraints. Good surface finish not only ensures quality, but also brings down the manufacturing cost. Surface finish is an essential parameter with respect to tolerances; it brings down the assembly time and eliminates the need for secondary operation, thus minimizes the operating time and paves way to overall reduction in cost. It is very essential to chose optimum parameters in metal cutting operations. Conventionally, the knowledge of the operator plays a vital role in the selection of optimum machining conditions. However, acquiring optimum values every time by even a skilled operator is nearly impossible. The non-linear nature of the machining process has forced engineers to look for more productive methods to reach optimization. The main objective of the present paper is to build a model to facilitate optimization problems in manufacturing processes. Due to improvement in the machining processes, a special concentration has been given on the life of a tool. To achieve that, the best way is to coat the tool with PVD and CVD techniques. By do
