Objectives of the course
At the end of the course the student should have acquired a good knowledge good knowledge of thebroad manufacturing processes used in industry for the manufacture of mechanical parts, as well as the capability to defining the manufacturing cycles with the use of a CAM tool.
1. Metal Casting
' Fundamentals of metal casting
' Expendable-mold casting processes: sand casting, shell moulding, precision casting processes
' Permanent mold casting processes: die-casting, pressure die-casting, centrifugal casting

2. Metal Forming
' Fundamentals of mechanical behavior of metals
' Fundamentals of metal forming and plasticity
' Bulk deformation processes in metal working: open die forging, close die forging, wire drawing, extrusion, rolling
' Sheet-metal processes: shearing, bending, drawing, hydroforming

3. Material Removal Processes
' Cutting and feed motions
' Fundamentals of cutting theory
' Turning: aims, machines, tools, clamping devices
' Drilling: aims, machines, tools, clamping devices
' Milling: aims, types, machines, tools, clamping devices
' Grinding: aims, types, machines, tools, clamping devices

4. Manufacturing and product cycle
' The production cycle and its articulation
' Definitions of: crossing or flow time, cycle time, time for preparation of machine
' Definition of direct, indirect, variable, semi-variable and fixed costs
' Analysis of the correlation between the characteristics of the product and the process
' Alternating cycles and assessment of the break-even point

5. Joining and Assembly Processes
' Introduction on the assembly of mechanical parts
' Gas welding processes
' Arc welding processes
' mechanical jointing technology

6. Layer Manufacturing Processes
' Introduction and economics
' Classification of technologies
' Industrial layer manufacturing processes: physical principles, machines and materials
' Conceptual modelling

4) Lab Training
Training activities will be provided in
' the classroom to go into more depth in topics presented during lectures
' the computer laboratory. Trainings are dedicated to the definition of machining cycle using a commercial CAM package widely used in industrial field
Students will be asked to develop a machining cycle covering the topics dealt with during lab trainings. With the help of the teacher, small groups of students should provide a report mandatory for the exam.

5) Grading
The final exam will consist of both an oral examination and the evaluation of the assignment carried out during the course. The oral test and the assignment will be evaluated separately and each of them must be sufficient. The evaluation of the assignment will account for 50% of the grade. Students must submit the report to the professor in advance before the beginning of the exam session.
