Objectives

Introduction of the concept of standardization in general and of its importance in Engineering. Acquisition of deep knowledge about the representation of the nominal shape and size of objects. Development of spatial visualization and technical communication skills. Introduction to the concepts of tolerance and interchangeability. Acquisition of basic knowledge about surface development methods. Introduction to diagrammatic drawings. Development of the ability to establish relationships between real mechanical systems for general use and their assembly drawings.

PERCENTUAL DISTRIBUTION

Estimated percentual distribution for the scientific and technological contents:
- Scientific component: 30 %.
- Technological component: 70 %.

LEARNING OUTCOMES:

At the end of the course, the students shall be able to:

1) Make drawings of objects in orthographic representation and with nominal dimensioning.
2) Read drawings of objects in orthographic representation and make the correspondent pictorial representations (isometric drawings).
3) Interpret the meaning of the dimensional tolerances inscribed in drawings and determine the ISO fits that fulfils the design requirements previously established.
4) Identify different standardized mechanical components present in some mechanical systems for general use; know their representation in assembly drawings and the accomplished elementary mechanical functions.

Program

STANDARDIZATION in general and in technical drawing. Drawing media and equipment, lines and lettering. Types of projection systems. Short references to the dihedric method. ORTHOGRAPHIC REPRESENTATIONS: basic conventions for views, the choice of views, partial views, auxiliary views, cuts and sections. The reading of orthographic drawings. AXONOMETRIC REPRESENTATIONS: pictorial representations (isometric drawings). DIMENSIONING: general principles, methods of execution, special indications and preferred numbers. DIMENSIONAL TOLERANCING: ISO system of limits and fits, general tolerances.
DIMENSIONAL AND GEOMETRICAL PRODUCT SPECIFICATIONS AND VERIFICATION: dimensional (ISO system of limits and fits, general tolerances) and geometrical tolerancing (individual and general tolerances), surface texture; fundamental tolerancing principle (principle of independency, envelope requirement, maximum material principle). MECHANICAL SYSTEMS AND COMPONENTS FOR GENERAL USE: screw threads, bolts, screws and nuts, washers.

Teaching methods and learning activities

Theoretical classes: detailed presentation of concepts related with the programme topics with help of practical examples.
Tutorial classes: students are asked to execute multview drawing objects, including views and general dimensioning, and isometric drawings of objects represented by multiview drawings, included in the text produced by teachers of the SDI/DEMEGI/FEUP.

Evaluation Type

Distributed evaluation without final exam

Attendance (estimated)	Participação presencial	48,00

Eligibility for exams

To attain frequency the student must not exceed the absence limit of practical classes (25% of the number of classes foreseen (P)).

Calculation formula of final grade

Final Classification = 70% of the exam test classification + 30% of the mini-tests classification.
When the final classification is equal or superior to 9,0 marks, the information (when existent) on the work developed in practical classes can improve that classification in a maximum of 2,0 marks.
Obtaining a final classification superior to 18 marks implies the need to do a complementary test.

Special assessment (TE, DA, ...)

In the special examination period, the students dismissed from frequency (items 3 a) and b), Article 4, General Evaluation Rules) will be asked to do an exam test which will include the two evaluation components.

Classification improvement

In the classification improvement test, to be done following article 10 of the General Evaluation Rules, the students will be asked to do an exam test which will include the two evaluation components.
