Cutting Cylindrical Surfaces
5.1 INTRODUCTION
Machining external cylindrical surfaces is performed using a rotating workpiece and a tool feed motion that depends upon the surface profile required. Cylindrical forms can be created using form tools that are fed across the rotating workpiece, while forms such as threads can be generated using a form tool that achieves form and generation cutting simultaneously. Internal cylindrical surfaces can be machined by drilling, enlarging, and boring and finished by the reaming process.
5.2 TURNING
Turning is a method of machining by cutting in which the workpiece carries out the main rotary motion, while the tool performs the linear motion. The process is used for the external and internal turning ...
