Design manufacturing integration is positively associated with NPD project efficiency, if product design and manufacturing personnel act in truly cooperative ways, overall project efficiency should increase.
Survey of 137 completed NPD projects. The degree of design and manufacturing integration significantly differed across the project groups in the expected direction.

By using templates, the time required for new product development is drastically reduced. At the same time incorporating computer-aided process planning into the system gives the designer a better understanding of the cost implications of the modified design with respect to manufacturing. The major challenge in implementing of such system is that any changes in the manufacturing facility have to be incorporated in the process plans stored. This can be a tedious job but can be overcome by using hybrid process planning approach instead of variant based approach.

Process planning task involves the development of a set of work instructions used for part transformation from its initial to final form. In the proposed system, the process plan module provides detailed information and description of manufacturing processes and machine tools required. The information includes: list of required machines; specific cutting energy for the work material; standard set-up and tear down times; number of tools required; and cost per hour of operation. A search heuristic is developed for the selection of appropriate process plan. If a process plan is not found in the database, a new process plan will be generated based on the defined design features, dimensions and required tolerance for finished product. The information from the developed process plan is used to calculate the manufacturing time and cost.

Secondary findings


Use of methods such as design for manufacturing (DFM) to encourage the integration of product and process design decisions has been associated with lower product costs and better conformance quality.
