Abstract

Machining parameters play a significant role for successful and efficient machining operations. Therefore, it is required to use the optimal parameters, especially for NC/CNC machines. Optimization of machining parameters can be defined as the appropriate selection of economical machining parameters in order to achieve maximum profit rate or minimum production cost or maximum production rate. The aim of this work is to maximize the profit rate by an optimization technique. Researchers have used many optimization techniques to solve the various engineering problems. This paper describes effectiveness and utilization of an optimization system, called Ants Colony Algorithm, for multi tool milling operations. The Ants Colony Algorithm based Optimization procedure evaluates the unit production cost, unit production time and maximum profit rate. The machining parameters such as optimal number of passes, cutting speed, feed, and depth of cut, are subjected to the constraints-maximum power, surface finish and cutting force. The Ants Colony System is a new kind of co-operative search procedure inspired by the foraging behavior of colonies of real ants. The problem has been solved by Ants Colony Algorithm with an example taken from the literature. The result is obtained through MATLAB software and it is compared with other methods.

Abstract

Due to the shortage of experienced process engineers and need for automation in manufacturing, the role of computers in process planning becomes inevitable. The integration of CAD, CAPP and CAM greatly shortens the product lead time. But true integration of CAD and CAM activities can take place only when the manufacturing information can be obtained from the CAD solid model and hence automate the process planning. The link between design and manufacturing represents a vast field of research, and its growth is crucial to the success of the CAD/CAM industry. This success mainly depend upon the, how reliably the data's are exchanged from various CAD systems to CAM systems. The existence of incompatibilities between information technology systems used in the process of design, engineering and manufacturing has given rise to various data exchange problems. These problems are of particular concern as more and more concurrent design is being undertaken by collaboration of different organizations that utilize different application programs and operating systems. The following section discusses the general problems that are often encountered during exchange of data, which result in increased cost and can be reduced or eliminated through the use of STEP.
