Cost benefit analysis of Rapid Manufacturing in Automotive Industries

Sunil Kumar Jauhar, K. M. Asthankar

Abstract


This paper deals with the application of rapid manufacturing techniques to save the time as well as cost of manufacturing of few critical components of automobiles. A case study of Inlet manifold of engine and Rotor of disk break is taken here to demonstrate the method. While working on this objective the aim will be to reduce the lead time required for tooling required for the conventional block-type investment casting process. There are strong incentives to reduce costs while increasing speed and accuracy in the current market. RP is an ideal method when the components are complex in shape because it substantially compresses the time for developing prototypes,
patterns and tooling. This method is even more promising on cost and time front. The capabilities to fabricate freeform surfaces, inbuilt cores, projections and supports are the unbeatable strengths of RP processes. The use of benefits in terms costs have proved that the adoption of RP technology is techno-economically justifiable for the Indian manufacturing industries. Rapid Prototyping have proved to be a cost-effective and time efficient approach for development of pattern making, thereby ensuring possibility for technology transfer in Indian manufacturing industries.
