At the end of the course, the student will have a base knowledge of mechanical technology and processing systems, the main production processes, the processing cycles and the machines needed for their realization.

INTRODUCTION TO THE PRODUCTION PROCESSES: the industrial production, the product design, concurrent design, the design of the product for the manufacture, assembly and maintenance, design criteria, the design of the product to the environment, the life cycle of the product, the choice of materials, the choice of production processes, lean manufacturing.
MECHANICAL TESTS AND THE PROPERTIES OF THE METALLIC AND NON-METALLIC MATERIALS: the mechanical behaviour of materials, tensile test, compression test, torsion test, bending test, hardness tests: Brinell, Vickers and Rockwell, impact test with Charpy pendulum. Composition of materials, classification of the materials used in industrial field. The structural properties. Resistance to corrosion, pickling. The physical properties. The technological properties. The production of steel.
Machining Processes and Machine Tools: fundamentals of machining, machine-tool structures, motions of a machine tool, classification of machine tools. The lathe, operations related to turning. Selection of turning parameters: forces that arise during a processing, determination of the cutting speed in the roughing and finishing, working time, security measures. Tools for metal cutting: introduction, chip formation, chip shapes, machining parameters, tool geometry, tool materials, tool wear, choice of cutting parameters. Lubrication.
MILLING: definition and procedures, milling machines, the geometry of the milling cutters, processes for milling, cutting parameters.
DRILLIG, REAMING AND THREAD: introduction, short hole drilling tools, tools for deep holes, the drill architecture and functional characteristics of the different types, twist drills, cutting parameters, reaming, machine tools for the construction of the threads.
MACHINING WITH LINEAR CUTTING MOTION AND RECIPROCATING RECTILINEAR MOTION: introduction, broaching (functional characteristics of a broach, construction parameters, cutting parameters), shaper, planer, slotting machine, sawing machines.
MACHINING WITH GRINDING WHEEL: definition of grinding and classification of various m.t., grinders, sanders, the lapping machine, the bench grinder.
FOUNDRY PROCESS: general information, sand casting, permanent mold casting, shell mold casting, environmental impact.
PROCESSING BY PLASTIC DEFORMATION: plastic processing, processing temperature, rolling, drawing, extrusion, forging and stamping.
PROCESSING NON-CONVENTIONAL: sintering, water jet machining, laser cutting and welding machines, electrochemical machining, ultrasonic machining.

Lectures and numerical exercises lessons related to foundry operations, processes for plastic deformation, chip removal. Lectures with practical examples to all the technologies covered in the course.

The final examination oral is to be able to distinguish between correct and incorrect statements on the topics discussed, in knowing how to answer theoretical questions on the principles and techniques discussed, in knowing how to apply the techniques to practical cases seen through resolutions of exercises. Rough the 3 parts are valued on an equal footing in the definition of the final grade.
