Academic Year 2021/2022

  • Teaching Mode: Traditional lectures
  • Campus: Bologna
  • Corso: First cycle degree programme (L) in Chemical and Biochemical Engineering (cod. 8887)

    Also valid for First cycle degree programme (L) in Environmental Engineering (cod. 9198)

Learning outcomes

Knowledge of the italian and european technical drawing's rules for the representation of mechanical components.

Course contents

Conventional instruments for drawing. Lines and a nomenclatures unified. Choice of sizes and scales.
Computer tools for drawing. Hardware description and the main devices. Architecture of a CAD system. Functions performed by the software.
The method of the orthogonal projections.
Sections and interpenetration of solids.
Norms and conventions in technical drawing. General criteria for dimensioning. Interpretation of assembly drawings and  performing of technical designs of single parts.
Conventional representation of mechanical elements with particular reference to the standardized use in chemistry plants (threads, riveting, welding, flanges, pressure vessels, piping, couplings, etc..).

Tables will be carried out in the laboratory relating to mechanical components using the two-dimensional software AutoCAD. During the exercises some assembly drawings will be examined in order to identify the main components responsible for the connections.

The student will be able to understand the functioning of the components themselves and their correct representation.

- Slides and booklets about lessons, available at the portal AMS Campus in the specific section of the course and on the IOL platform.

Teaching methods

The course consists of 3 credits, CFU, in which they are also integrated theory lessons, that relate to the basic rules of the industrial technical drawing to guarantee the student to have all the necessary tools to realize two-dimensional drawings, according to Italian and European regulations.

To the theory lessons follow practical exercises to give to students the basic instructions for using the two-dimensional CAD software Autocad. Assistance to students is provided in the preparation of mechanical drawings using the software.

Assessment methods

The examination at the end of the course aims at assessing the achievement of educational objectives:

• Basic knowledge of mechanical design according to Italian and European regulations
• Knowledge of the software Autocad and its use
• Use of Autocad for the drafting of mechanical drawings according to regulations

The exam consists of a graphic test, accompanied by a verification of the theoretical part.

The graphic test is performed by drawing simple mechanical components with the same CAD program used for the exercises during the course and the theoretical test is carried out by asking the student, during the written test, to answer a question regarding the theory dealt with during the lessons.

The verbalization of the outcome of the written test is bound to the presentation and discussion of the drawings produced during the course of the lessons.

Teaching tools

Lessons will be held in a computer lab, under the direct guidance of the teacher, whiere PCs are available to the student to make the CAD drawings, using AUTOCAD software.

Each student is given the opportunity to install the software on his PC, with academic license authorized.
