This paper aims to present a theoretical approach and a case study within a research upon product and process design methods in terms of manufacturing and assembly-supported by DFMA(Design for Manufacturing and Assembly)techniques.Application of the integrated design capabilities provided by DFMA approach is illustrated with a case study on the development of a technological device for automated assembly of an industrial electrical plug inlet.The analysis and redesign using DFMA philosophy and advanced 3D design capabilities provided by CATIA V5 is an advanced engineering method for designing an innovative product in order to simplify the product,to quantify improvements and to reduce manufacturing and assembly costs.The new design of the studied product has been compared with the existing one from the aspect of parts quantity,handling time,assembly time and design efficiency.Finally,the study presents also some related conclusions together with further research directions.
