The development of a structured approach to the design for economic manufacture of engineering products
The present work has been concerned with establishing a rational approach to product design for economic manufacture. This has invloved the de velopment of an organised design approach together with proposals for a structure for an ideal organisational system to support a design for economic manufacture activity. Surveys of relevant literature and industry have been conducted to review practices and techniques which are currently available to the industry to aid the processed of design for economic manufacture. As a result of the survey it was possible to define analyse the major areas of activities in relation to product design and manufacture to identify where maximum attention should be given by the management and designers to effect economy of product manufacture. It was concluded that although the mangement in several companies have adopted certain policies towards designing for economic ' manufacture, a more structure and organised approach is required to meet the growing need to apply design of economic manufacture as a means of reducing manufacturing costs. As a result of the analysis, it has been POSBible to identify the actions which must be taken at the different stages of product design and devleopment to ensure economy of manufacture. These findings are supported by two design case studies which individually demostrate the type Of Cost savings which can be achieved by giving consideration to the product concept at an early stage of design, in addition to optimising the component desine for manfacture. The above case studies highlighted the fundamental factors which influence the product manufacuring COBtSThe above work has allowed proposals to be made for an overall integrated organisational system which should aid the process. of design for economic manufacture in most engineering companies.
