Task One:  Brief History of Computer-Aided Process Planning

      Process planning is a manufacturing tool used to translate design information into the process steps and instructions to efficiently and effectively manufacture products. Because many computer-aided tools are applied throughout the design process, Computer-Aided Process Planning (CAPP) evolved to simplify and improve process planning and reach more effective and efficient use of manufacturing resources.

      Process plans include all actions necessary to develop detailed instructions to produce a part or material.  They were originally drawn by hand. Due to the detail of typical process plans, developing them was very time consuming. They often contained errors.  The plans were not identical; they varied depending on the individual that created each one.  There was no way to entirely coordinate the plans, and they could not be easily altered.

      As computers were inducted into manufacturing science, CAPP was developed as a far more efficient way to process plan. The basic functions of a computer cut out many of the time consuming steps necessary to draw a plan.  The plan could also be easily reproduced.  Factory communication was simplified, and it was possible to correct and expand the plans.

      The Organization for Industrial Research, Inc. (OIR) was the first company to develop a commercial CAPP system.  In 1979, the Cleveland division of the General Electric Light Equipment became its first customer.  After installing over 150 systems, OIR was merged into Computervision in 1984.  OIR's Multicapp system contained detailed group technology classification and retrieval capabilities.  However, it was used as an electronic pencil by most customers. The defense and aerospace industries needed to keep elaborate manufacturing records, so they were the first industries to use CAPP to develop mainframe-based complex data management systems.

      Computer-Aided Process Plans can greatly increase efficiency and cut costs.  They are wonderful tools for manufacturers that hope to be competitive and successful.

Task Three:  How Our NCT Has Advanced Scientific Knowledge

 

Computer Aided Process Planning (CAPP) has advanced scientific knowledge by providing many significant benefits in the manufacturing field.  Through the use of CAPP, manufacturers are able to quickly respond to engineering changes.  The user can also easily and quickly update information from a central base. Using CAPP, people have found that their costs were reduced and there were fewer errors in the calculations made. Using CAPP greatly lessens the waste of time and space.  It provides maximum efficiency.

CAPP is extremely effective for manufacturers that deal with a high number of products and process steps. Using these tools, manufactures are able to have a higher competitive advantage.

The development of CAPP was a major stride in manufacturing science.  When applied and utilized, this type of process plan can significantly improve a manufacturer's competitive advantage.
