Turning

Turning is a machining process for generating external surfaces of revolution by the action of a cutting tool on a rotating workpiece, usually in a lathe. This article discusses the process capabilities of turning over other machining operations and describes the classification, controlling methods, attachments, and accessories of a lathe machine. It reviews the design and various operations of single-point cutting tools in turning. In addition, the article discusses the influence of various factors on selection of equipment and machining procedure for a specific part. These include the size and configuration of the workpiece, equipment capacity, production quantity, dimensional accuracy, number of operations, and the surface finish. It presents examples that describe or compare equipment and techniques for production applications. Finally, the article provides a discussion on the classification and compatibility of cutting fluids.
