Computerized systems have been quite successful planning rotational parts, but have had limited success planning three dimensional parts. 6.1 Advantages Determines the manufacturing sequence, equipment used, estimates of fabrication time, and tooling. Provides a structured methodology for the development of route sheets and manufacturing specifications. Provides information useful in predicting manufacturing cost. 6.2 Disadvantages Computerized systems implement only variant process planning.
Computerized systems operate in vary restricted domains.
Computerized systems require company specific and site specific data. An extremely large amount of data must be evaluated resulting in large compute time requirements. Objective is to design a product so that it can be easily disassembled and separated into its constituent materials so that these materials can be disposed of in an environmentally safe process. Encourages recycling of materials Extends landfill space and reduces groundwater pollution from seepage of unsafe materials discarded in landfills. 7.1 Advantages Currently is a marketing advantage due to heightened public concern.
