Course contents summary
Methodologies and interdisciplinary skills required in the different
stages of the technical product development and their application in practice.
Selected topics of advanced machine design.
Use of a professional CAD software for modeling and graphical representation
in mechanical engineering.
Methods for the graphical and technical reports of mechanical devices.
The stages of the development process of a technical product. Typical activities of the design engineer in the manufacturing company. Impact of the international market environment. Role of individual personality in team work. Myers-Briggs personality test. Motivation and dynamics of working teams. Methods to activate creativity and promote product innovation. Patents: Typical structure and objectives of intellectual protection. European legislation in the field of machinery and pressure vessels. Review and integration of know-how and skills acquired during the undergraduate degree in the context of the design and development of real commercial products.
Project 1) Development of a two-cylinder compressor: Thermodynamic cycle, four bar linkage analysis, dynamic load analysis of components, electric motor drive and belt transmission, structural check of the main components of the compressor, evaluation of Buy or make strategies, cost estimate, design of compressed air tank.
Project 2) The second project is developed in direct collaboration with the important mechanical company COMER INDUSTRIES and varies year after year. It includes a series of lessons and laboratories developed with the direct participation of company technicians. The objectives of the activities are: • To present the company's technical and production organization, characterized by a strong commitment to innovation, and its range of products • Understand the process and the development methods of a real mechanical product (from design to testing and marketing) for the global market • Guiding the learning of modern design and virtual development methods for new products by applying them to a COMER product.

Assessment methods and criteria
The exam is oral and involves the discussion of technical reports developed in groups and the individual presentation of a technical device.
In parallel there is an individual practical test of the use of CAD software.
The examination of the group's activities takes place by appointment.
