Computer-aided process planning

Process-planning steps were introduced in the previous section. This section discusses the tools used to carry out these steps. Manual process planning, which relies on human experience, will not be discussed. The tools discussed in this section are those used in computer-aided process-planning systems. They are used to assist the human planner in developing process plans. Most of these tools have been used in practical process-planning systems. Methodologies or algorithms used only in advanced research will not be introduced here. 

The benefits of computer-aided process planning systems have been documented in several industries. Such systems can reduce planning time from days to hours and result in large cost savings.

Computer-Aided Process Planning (CAPP) Computer-aided process planning systems rely on a computerized knowledge base to provide support for the expert process planner. Through their use in process planning, it is possible to raise the productivity, reduce the cost, increase the consistency, and lower the skill requirements for the expert process planner. Two major methods are used for CAPP generative CAPP and variant CAPP (Marri et al. 1998).
