With the rapid development of Computer Integrated Manufacturing (CIM), Computer Aided Process Planning (CAPP) is becoming increasingly important. This book discusses process planning and how to implement computerized process planning systems. In essence, the aim of the book is to provide a comprehensive review of CAPP from a manufacturing engineering perspective. Strong emphasis is placed on the understanding of the fundamental principles allied with the implementation of CAPP systems. The book also provides state-of-the-art knowledge on all aspects of computerized manufacturing processes planning technologies. Criteria on how to evaluate CAPP systems are also imcluded. The book can be used as a graduate text for courses on Manufacturing Process Planning and Advanced Manufacturing Engineering. It is also suitable as a reference book for guiding research activities in the area of developing CAPP systems and production integration. Production managers and manufacturing engineers should also find this book useful to updte their knowledge.
