OVERVIEW

Advanced Technical Drawings and Mechanical Design through the integrated use of the most advanced Virtual Prototyping tools, in particular Computer Aided Design/Engineering (CAD/CAE) tools for solid parametric modelling and for the concurrent optimization of mechanical systems.

AIMS AND CONTENT

LEARNING OUTCOMES

To provide, by means of theoretical concepts and project-based learning, the knowledge of modern CAD/CAE (Computer-Aided Design/Engineering) modelling techniques aimed at developing a Digital Mock-UP (DMU) of complex products. The course shall deal with an in-depth analysis of real-world assemblies, taken from the industrial scenario. Traditional computer-aided drawing tools will be recalled (parametric CAD), followed by an in-depth description of advanced virtual prototyping methods (CAE-centered desing and 3D modelling via top-down approach).

AIMS AND LEARNING OUTCOMES

- Knowledge of a methodological design approaches for setting-up the sequential activities to be carried out in order to optimally perform the design of a generic mechanical system;

- Knowledge of some CAD/CAE software tools for mechanical drawing, in particular PTC Creo and OnShape;

- Ability to set up a coordinated and concurrent CAD/CAE-based design activity on a group of people (collaborative design);

TEACHING METHODS

The course is structured into equally subdivided theoretical and practical lectures.

SYLLABUS/CONTENT

- Product lifecycle and phases of product development;

- Review of mechanical drawing, Geometric Dimensioning & Tolerancing (GD&T) and related software tools - Computer-Aided Tolerancing (CAT);

- Optimization of chains of tolerances according to the production technology of the single components;

- CAD-CAE integration, CAE-centerd design and development of 3D models with top-down approach (Use of part skeleton and assembly);

- Morphological optimization of mechanical components according to the maximum achievable precision;

- Optimization of mechanical systems oriented towards ease-of-assembly and minimum cost of construction (Design-for-Assembly & Design-to-Cost);

- Information management in the product life cycle, PLM systems;

- Methods and tools for collaborative design (collaborative PLM - Cloud-based CAD).

EXAMS

ASSESSMENT METHODS

The written exam aims at verifying that the student is able to carry out the general design of a mechanical assembly (having similar complexity as the systems illustrated during the lectures).

A CAD/CAE project is also required. The design of a mechanical assembly, to be implemented with the CAD/CAE methodologies explained in class, is assigned to each student. The oral evaluation consists of a detailed presentation/discussion of the project. The student shall submit a written report (30/40 pages) at least 10 days before the day of the exam, summarizing:

- the project phases;

- the difficulties encountered while carrying out the work;

- methods and techniques employed to overcome such challenges;

Along with the report, the student is required to deliver a DVD with all the final project files. These files shall be produced with PTC Creo.
