Productivity improvement in manifold machining using CNC machines

Abstract

This report focuses on the different methods to improve productivity at management level, at the machine shop and of machining methods. The various parameters effecting machining productivity i.e., cycle time, set-up time, idle time, operator skill level etc. including how CNC machining helps in optimizing these parameters are discussed and analysed in this paper. Effects of different cutting parameters like cutting speed, feed rate, depth of cut, effect of coolant etc. are also examined. Various methods of machining for different processes which help to improve the productivity of the process are explored. A case study on machining of an aluminium manifold is done in which the existing process for machining is analysed and various experiments are performed in order to find out the optimum cutting parameters and minimizing the cycle time of production of the manifold. The result helps to reduce the cycle time by a significant amount thereby reducing the total cost of production and increasing the production rate of the component with negligible capital investment.
