090912 - COMPUTER AIDED MANUFACTURING
This course introduces the student to the fundamentals of manufacturing processes used in discrete-part fabrication along with their needs in terms of automation and computer-based intelligence, according to the smart manufacturing paradigm.
Risultati di apprendimento attesi
Lectures and other didactic activities will allow students to:
know the structure and behavior of materials (metals);
understand the basic design requirements of a product, and in particular geometrical product specification and verification;
know the basics of manufacturing and transformation theory;
understand the classification of manufacturing processes and systems;
know the basic principles, tools, and machines of the considered processes (machining processes);
design feasible manufacturing and inspection processes for a product;
know the computer numerical control (CNC) and the CNC machines;
understand the needs and the benefits of the adoption of CAD/CAM, CAPP and CAIP techniques;
understand the need for automation and computer-based intelligence in manufacturing.
Within the semester, each student has to carry out a mandatory team project work. Each team will be composed of up to 4 students. This way the following additional learning outcomes are expected:
students develop the capability of taking autonomous decisions in an industrial-like activity, applying the theoretical and practical knowledge acquired during lectures to an unstructured problem;
students present and orally defend the results of the decisions related to the project-work.
With respect to the study programme, the course will allow to reach the following generic learning outcomes:
capability of knowledge and understanding,
capability of applying knowledge and understanding,
capability of making judgements,
capability of communication.
Introduction to manufacturing
Production technologies, production processes, quality control and inspection, transformation theory. Elements of technical drawing, geometric dimensioning and tolerancing, surface quality assessment. Basics of mechanical behaviour of engineering materials: tensile test, compression test, hardness test, impact test, fatigue test.
Industrial Geometrical Metrology
Geometrical product specification and verification. Coordinate measuring machines and systems. Probing systems for CMM. Coordinate measuring system algorithm and filters. Performance evaluation.
Machining processes and Machine Tools
Theory of metal cutting: orthogonal cutting, cutting angles and cutting parameters. Pjispanen chip formation model. Cutting forces and Merchant equation. Machining operation and machine tools: turning, milling, and hole making. Cutting-tool technology: tool geometry, tool wear, tool life. Machining economics: production cost, production time, optimization of cutting conditions.
CNC Machine Tools
Historical hints on numerical control of machine tools. CNC driving system components. CNC control loop. Components of CNC systems. CNC machine tool performance and accuracy: introduction to volumetric error compensation. Turning and machining centers: characteristics and configurations.
The operation and programming of CNC machine tools. STEP-NC System. Process planning and manufacturing systems. Approaches to geometric modelling. Computer-aided design and manufacturing (CAD/CAM). Computer-aided process planning (CAPP). Computer-aided inspection planning (CAIP). Smart manufacturing and Industry 4.0.
CAD/CAM Project Work
Within the semester, each student has to carry out a mandatory team project work. Each team will be composed of up to 4 students and has to solve a process industrialization problem consisting of both machining and inspection planning. The team project work has to be reported and discussed by the end of the semester.
The students should have knowledge related to:
calculus and geometry;
the basics of physics and mechanics;
the basics of measurements;
the basics of automation and control engineering.
Modalità di valutazione
The final grading is based on the mandatory team project work and on an oral examination.
During the semester the students will be grouped in teams in order to solve a process industrialization problem consisting of both machining and inspection planning. The team project work has to be reported and discussed by the end of the semester (capability of applying knowledge and understanding and of communication).
The oral examination will consist of:
open questions on the basic topics of the course (capability of knowledge and understanding, capability of communication);
open questions aimed at highlighting the student’s ability to reason and develop links among the different topics of the course (capability of applying knowledge and understanding, of making judgements, and of communication).
