AIMS AND CONTENT

LEARNING OUTCOMES

To provide a deeper knowledge on the manufacturing processes based on material removal, with particular regard to: modelling and analysis of chip formation, machine tools and their operations, NC and programming, economical optimisation of machining. Non-traditional machining processes, additive manufacturing and reverse engineering are also studied.

TEACHING METHODS

The course is based on lectures, numerical exercises and laboratory of machine tools.

SYLLABUS/CONTENT

Principles of metal cutting: kinematics and dynamics of machining; tool life; cutting fluids; machinability. Machine tools classification. Turning: geometry and representations of the single-point tool; modelling of surface  microgeometry; turning operations; types of lathes; forces and power; elastic deflections.  Milling: geometries of milling cutters; up-cut and down-cut; cycloid trajectories, chip thickness; milling operations; gear cutting, milling machines, maximal and mean power. Drilling: tools; geometry of twist drills; drilling machines; forces, torque and power. Reaming: tools, machines. Machining by straight movement: motion analysis, machine tools and operations. Grinding: designation of grinding wheels; abrasive and bond materials; geometry of microchip formation; force and power; grinding machines and operations; centerless grinding. Gear cutting: spur and helical gears; parameters  and metrological controls; envelope processes; hobbing process and machine; geometrical errors. Numerical control of machine tools: NC machines; types of control, interpolations, programming; ISO codices. Economical estimates of machining: time and cost for a batch; optimisation algorithms. Main non-traditional machining processes: AJM, USM, EDM, ECM, LBM. Additive manufacturing technologies. Reverse engineering: procedures, scanning 3D, CAD model.
