Chapter 4 Machine Tools and Machining Operations for rotational parts,Abstract Machine parts are basically separated into two: rotational parts and non-rotational parts. This chapter will focus on the required machine tools, cutting tools and machining operations for rotational parts. The lathes and lathe cutting tools, including main mechanism of CA6140 and the structure of turning tools are introduced. In the same time, the work principle of the machining methods of grinding, some hole-produce
