Abstract

Machine tool structures made of non conventional materials have seen tremendous progress in the manufacturing industry. Conventional material such as cast iron is now being replaced with materials having superior properties. This paper tries to review the development of alternative materials for the machine tool structures over the last three decades that were found to have beneficial properties than the conventional cast iron. To support the higher speeds of modern machine tools built to increase productivity and at the same time maintain the surface finish of the work pieces, the requirement of alternatives to cast iron have emerged. The properties of the alternative materials are summarized and compared with cast iron.

Abstract

In manufacturing, assembly is one of the major activities that combine the machined components into final product. Decision on assembly sequence (line balancing) and appropriate facility layout adaptable to takt time with cost benefit is a challenging task. This paper presents an effective cost model to configure the assembly system based on cost per piece. The proposed cost model is experimented with a prototype assembly system established in this research to demonstrate its effectiveness. The experiments conducted for pneumatic cylinder assembly with different takt times indicates that the proposed procedure can be used effectively to configure the assembly systems to promote lean operations.
