Abstract

Technological development and its commercialization are the prime factors for all-round development of any nation. The management of technology development along with its business and commercial exploitation are key areas to be identified and properly understood to remain competitive in this global market. Some technologies are partially commercialized due to improper technology management and one such example is sinter-forging or powder metallurgy forging (PMF). The technique combines advantages associated with two well-known techniques i.e. powder metallurgy and conventional forging and uses pressed and sintered metal powder performs as starting material. It is well suited for mass production of precision, net shape and high-performance components virtually without scrap loss at competitive rates. The authors have carried extensive research in this area and it is their firm believe that the technique may emerge as an advanced progressive manufacturing technology. The present paper highlights its techno-economic aspects and suggests possible research areas requiring proper management.

Abstract

Friction condition between deforming tool and workpiece in metal forming are of the greatest importance concerning a number of factors such as force and made of deformation, properties of the finished specimen and resulting surface roughness. The relative velocity between the workpiece material and the die surface together with high interfacial pressure and/or deformation modes will create the conditions essential for adhesion in addition to sliding.
