At the end of this lesson, the students should be able to : (a) Describe the basic functional principles of machine tools. (i) Illustrate the concept of Generatrix and Directrix. (ii) Demonstrate Tool – work motions. (iii) Give idea about machine tool drives. (b) Show configuration of basic machine tools and state their uses. (c) Give
Weck, “Handbook of Machine Tools," 4 vols., Wiley, 1984. INTRODUCTION. Machining processes, which include cutting, grinding, and various non- mechanical chipless processes, are desirable or even necessary for the following basic reasons: (1) Closer dimensional tolerances, surface roughness, or surface-finish
A material removal process in which a sharp cutting tool is used to mechanically cut away material so that the desired part geometry remains. •Most common application: to shape metal parts. •Machining is the most versatile and accurate of all manufacturing processes in its capability to produce a diversity of part geometries
Material Removal Processes. • Machining is the broad term used to describe removal of material from a workpiece. • Includes Cutting, Abrasive Processes (grinding),. Advanced Machining Processes (electrical, chemical, thermal, hydrodynamic, lasers). • Automation began when lathes were introduced in 1700s. • Now have

Modern Machining Process. 1.1. Introduction. As a result of the advances in machine tools and cutting tool technology in recent decades, many of the conventional machining processes such as turning, milling and drilling have become cost-effective, flexible and high- throughput manufacturing processes for producing high
Machining of cured FRPs is carried out by conventional or nonconventional material removal methods. The conventional methods most frequently used are edge trimming, milling, drilling, countersinking, turning, sawing, and grinding. Among the nonconventional machining processes are abrasive waterjet and laser beam
