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.
In order to improve the final grade, group of students may carry out a non-mandatory project work. 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, as a written report, 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.
1. 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 behavior of engineering materials: tensile test, compression test, hardness test, impact test, fatigue test.
2. Machining processes: Theory of metal cutting: orthogonal cutting, cutting angles and cutting parameters. Pjispanen chip formation model. Cutting forces and Merchant equation. Cutting-tool technology: tool geometry, tool wear, tool life. Machining operation and machine tools: turning, milling, drilling, reaming, boring. Abrasion processes, grinding, lapping, honing. Machining economics: production cost, production time, optimization of cutting conditions.
3. Quality control and inspection: Geometrical product specification and verification. Measuring geometric features, coordinate measuring machines and systems. Quality control and process capability.
4. Automation of manufacturing processes: Definitions of numerical control and automation. Historical hints on numerical control of machine tools. CNC machine tools: general characteristics and structure. Number of axes and main components; actuators and transducers. CNC machine tool performance and accuracy: introduction to volumetric error compensation. CNC machine tool evolution: turning centers and machining centers, characteristics and configurations. Tool changing devices. Pallet changing devices. Integration in manufacturing systems.
5. Computer-aided manufacturing: The operation and programming of CNC machine tools. Process planning and manufacturing systems. Computer-aided design and manufacturing (CAD/CAM). Computer-aided process planning (CAPP). Computer-aided inspection planning (CAIP). Smart manufacturing.
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 an oral examination, which consists 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).
The student has the possibility to improve the final grade up to +4/30 if, during the semester, she/he has carried-out a non-mandatory project-work on one of the topics of the course, presented it as a written report and, at the end of the semester, defended the results in an oral presentation.
