Cam is a key part of the automobile engine and other internal combustion engines. Its quality and processing efficiency have a direct influence on the quality of automotive and the development of the entire automotive industry. In this book, our aim is to achieve low cost, high quality and intelligent manufacturing for cam grinding. Part 1 is to study a novel grinding strategy for keeping the grinding depth constant during the cam grinding process. The GA-BP network in process parameters optimization in NC camshaft grinding is modeled and experimentally tested. The second part is about a hybrid method integrating Rough set (RS) and case based reasoning (CBR) to engineers selecting the optimal process conditions for a new camshaft product. The third part is about laser assisted machining in ceramic cam parts.
