Objectives of the course
The course aims to introduce the fundamental engineering topics in the field of metallic material mechanical working, giving a frame of reference on the productive processes adopted in the mechanics parts manufacturing. In particular, the course carefully develops both the physics principles, and the analysis methods concerning the foundry processing, as well as the material removal processing.
Expected skills
At the end of the course the student must be able to frame the different typologies of a manufacture's mechanical working, to know the physics principles of the different foundry and cutting processes, to dimension the main kinematics and energetic parameters, to account for the different wear mechanisms occurring to the adopted tools, and to dimension their relative properties and life in order to avoid collapse risks and check duration of them.
Prerequisites
Calculus I, Calculus II, Linear algebra, Physics, Technical communication methods, Logistics and Industrial Production, Mechanics, Probability and statistics, Introduction to theoretical and applied mechanics, Electrical machines, Fluid Mechanics, Mechanics of materials Applied mechanics and machines, Heat transfer, acoustics and lighting engineering, Materials for Engineering, Industrial plants, Quality and Metrology.
Syllabus
Characteristics of materials: stress-strain relationship, hardness tests. Foundry processing.: casting in transient and in permanent moulds. Chip formation and wear mechanism of cutting tools. Taylor model; time and costs in production acivities. Fundamental material removing processes. Numerically controlled machines and NC programming. Tools and techniques of precision metalworking. Abrasive Processes. Welding and assembling processes.
Laboratories and/or exercises
During the classroom practice students face some practical problems concerning the dimensioning and planning of the processes studied at lesson. In particular, in the field of foundry processes students develop their own tool and process design on CAD instruments in the IT laboratory; in the field of material removal processing, practicing activities focus on several applications of the theoretical arguments developed during the lessons, and using calculus instruments for determining the interactions between the cutting tool and the work.
The student will have to prepare a report of his individual work, including a detailed description of the solving methods adopted.

Revisions / Exam
The degree of learning evaluation that a student has acquired is based on three elements:
- The individual report prepared by the student during laboratory practice, aimed to quantify its ability in developing the required manufacturing methods;
- A written test about 2 hours lasting, which aims to identify the capacity to face calculus problems similar to those developed during the practice;
- An oral test, in order to establish the student's theoretical performance as well as its ability to conceptually discuss the proposed topics doing the necessary scientific and logical links between the physical quantities involved.
