Metal cutting and machine tools

Metal Cutting and Machine Tools is a core manufacturing engineering subject that deals with the principles, mechanics, and applications of machining processes used to shape and finish metallic components. The course introduces the fundamentals of metal cutting, including chip formation, cutting forces, heat generation, tool wear, and surface integrity. Emphasis is placed on understanding the interaction between the cutting tool, workpiece material, and machining parameters to achieve dimensional accuracy, high productivity, and optimal surface quality.

The course also provides a comprehensive overview of conventional and modern machine tools such as lathes, drilling machines, milling machines, grinding machines, and CNC machine tools. Students learn the construction, working principles, kinematics, and operational capabilities of these machines, along with tool geometry, tool materials, cutting fluids, and work-holding devices. By integrating theory with practical considerations, the course equips learners with the knowledge required to select appropriate machining processes, tools, and cutting conditions for industrial manufacturing applications.
