Abstract
This paper deals with a new method that provides an integrated approach to design and manufacture of gas turbine components by using the group theory and customizing standard computer-aided design and nmanufacturing system. With this approach, time-consuming and iterative design procedure and process-planning are automated and become more efficient. Due to the intricate and diverse nature of gas turbine components, grouping them is not easy as in other industries. A possible way of grouping the gas turbine components based on design and manufacturing attributes on a broad basis is presented. A case study of high pressure turbine disk is included with illustrations for design and process-planning of this component. The proposed system is implemented on a personal computer and offers an alternate solution to sophisticated and expensive mainframe-based system. (Author)
