The Advances of Computer-Aided Process Planning



Tommy Chang


Process planning is a vital function in manufacturing. It provides instructions on how to make a component from the raw material to its final shape. Because of the lack of skilled process planners and the desire to automate manufacturing, computer-aided process planning systems have been developed. Although there are many existing systems, some of which have been adopted by industry, none of the current planning systems fully satisfy the requirements of industry. This report first focuses on an introduction to computer-aided process planning approaches. Two approaches (variant and generative) are discussed. The concept as well as implementation of each approach is shown. Several current computer- aided process planning systems (both variant and generative types) are discussed in greater detail. The report also discusses pros and cons of using each approach. A table which summarizes twenty eight systems is presented; reference information for each system is listed in the table. This report also discusses the future development of computer-aided planning. A glossary of process planning terminology is included.
