Requirements Analysis: Process Plan Specification - Workstation Level



Kimberley Ellis, Albert T. Jones, Yung-Tsun Lee


The Computer-Aided Manufacturing Engineering (CAME) program is developing a number of integrated software toolkits for design, manufacturing engineering, and production operations. One of these toolkits is the Manufacturing Engineering ToolKit (METK). The goals of the METK project are 1) to develop generic interface specifications, data structures, information models, and data validation methodology for manufacturing engineering software; and, 2) to demonstrate an integrated toolkit using commercial, off-the-shelf software applications. An initial prototype for the METK was developed in order to conduct a requirements analysis for the various interfaces. That prototype contained software applications to implement the following functions: product data management, workflow management, computer-aided design, generative process planning, and Numerical Control (NC) validation. The concept of a process plan was used to integrate the process planning and NC validation applications. This document describes the results of the requirements analysis for the process plan specification for a workstation containing a single machine tool and its operator. It will provide a scope and domain for the specification, a review of the related literature and standards, units of functionality, and the definition of required application objects.
