Basic elements of technical communication languages in the field of mechanical engineering. Techniques for representation of the morphology and definition of design and operational characteristics of mechanical components. Development of appropriate operational capabilities in the field of mechanical design.
The course includes: theoretical lectures - object lessons, held in the informatics hall, about the key features of the software Bentley Microstation - exercises carried out by the students tutored by the teacher, taking advantage of Microstation, regarding simple drawings and design problems.
Standardization of technical drawings. Classification of the drawings. General standards: formats and sizing, title block, lines, scale. Representation methods: classification of projections. Introduction to perspectives. Orthogonal and oblique projections. Orthographic projections. Use of orthographic projections: layout and choice of views. Sections: rules, types. Dimensioning: standards, systems, dimensions of geometric elements, functional and technological dimensioning. Dimensional errors: ISO system of tolerances, types and calculation of couplings, general tolerances, tolerance of chained dimensions. Microgeometric errors: definition, measurement, symbols and choice of the roughness. Macrogeometrical errors: geometric tolerancing in outline.
Threads: elements of a thread, types, representation and dimensioning.
Threaded connections elements: bolts (nuts and screws), studs, inserts, unscrewing devices. Removable non-threaded connections elements: keys, mention of plugs, safety rings and stops, splined coupling joints. Outline of permanent connections. Materials for mechanical engineering: designation and notes on mechanical properties, types of materials and heat treatments.

INDUSTRIAL DRAWING
The written exam consists of a Multiple Choice Question theory test. Oral exam deals with the discussion about a drawing exercise and specific questions of the test, inclusive of the relevant theoretical topics.
The Multiple Choice Question theory test includes questions about 10 topics of the course. A maximum of 3 questions for each topic must be answered, for a total of roughly 20 questions.
The drawing exercise must be preferably carried out by means of a CAD software and completed with all of the information (quote, tolerances, roughness, ...) needed to ensure compliance with the requirements prescribed in the text of the exercise.
Pre-requisites:
Basic knowledge on how a computer works and on Windows® operating system.
