Development of standardization concepts in Mechanical Engineering Drawing. Improvement of spatial visualization and technical communication skills. Introduction to design drawing. Introduction to the functional analysis of mechanical systems with the detail drawing of some components. Development of the ability to establish relationships between the design, product definition, manufacturing and verification phases.
At the end of the course, the students should be able to:
1) Make assembly drawings in orthographic representation and item lists of mechanical systems, with the selection of standardized mechanical components.
2) Read assembly drawings in orthographic representation and make the corresponding exploded views.
3) Make detail drawings of mechanical systems components, through a functional analysis based on the corresponding assembly drawings.
Technical skills acquired in this Unit are important for course units like Computer Aided Design and Manufacturing, Manufacturing Processes, Introduction to Machine Design and Final Mechanical Project in general.
Principles and rules for the execution of technical drawings (Technical Drawing Unit). Principles and rules for indication of dimensions and related tolerances (Technical Drawing Unit). Ability to read drawings of objects in orthographic representation and to make the correspondent pictorial representations (Technical Drawing Unit). Basic knowledge about Manufacturing Processes and Product Development techniques (Introduction to Mechanical Engineering Unit).
STANDARDIZATION in mechanical engineering drawing. MECHANICAL SYSTEMS AND COMPONENTS FOR GENERAL USE: screw threads, bolts, screws and nuts, washers, pins, circlips and retaining rings, rivets, welding, shafts, splines, keys and keyways, rolling bearings, seals for dynamic application, springs and gears. GEOMETRICAL PRODUCT SPECIFICATION: complements of dimensional tolerances (toleranced dimensions properties, functional dimensioning, manufacturing dimensioning, angular tolerances of prisms and conical tapers); geometrical tolerancing (tolerances of form, orientation, location and run-out; datums and datum-systems); general tolerances; indication of surface texture; specification and interpretation of geometrical tolerances (principle of independency, envelope requirement, maximum and least material requirements and reciprocity requirement); edges of undefined shape; drawing indications for moulded parts. DESIGN DRAWINGS: assembly drawings in orthographic representation and item lists, with the selection of standardized mechanical components. DETAIL DRAWINGS: geometric dimensioning and tolerancing (functional analysis, dimensional chain analysis, etc.). PRODUCTION DRAWINGS: manufacturing drawings (the need for tolerance transfer) and general assembly drawings (orthographic representation and exploded views of assemblies). Short reference to technical catalogue drawings. DIAGRAMMATIC DRAWINGS.
Estimated percentual distribution for the scientific and technological contents:
- Scientific component: 40 %.
- Technological component: 60 %.
Lectures are based on detailed expositions of each basic topic of the course, illustrated by the presentation of application examples.
Tutorials are based on brief presentations of complementary topics of the course, intercalated with the resolution, by the students, of exercises considered relevant and that can be found in the main bibliography of the course unit.

Students have to attend to 75 % of the classes, according to Article 7 of the Specific Rules for FEUP's Students Assessment.
Final grade = (A + B + C) / 3.
where:
A - is the "assembly drawing + mechanical components" test mark;
B - is the "detail drawing + tolerancings" test mark;
C - is the average mark of four work assignments.
Carrying out the two individual evaluation tests is a necessary condition for considering that exists a minimum number of elements that allows a correct assessment of each student. The approval in the course unit depends on the average of the two tests marks be greater or equal than 7,0/20.
The average mark of the work assignments will be the result of the weighted mean of the marks of the following four works:
- Orthographic representation and nominal dimensioning (0,5 weight).
- Assembly drawing (1,5 weight).
- Exploded view (0,5 weight).
- Detail drawing (1,5 weight).
It will take place an optional resit exam (it will cover one test out of two).
The attainment of a final grade, in the course unit, greater than 18/20 must be confirmed by a complementary test.
According to items 9.1 b) and c), 9.2 to 9.4 in Article 9 of the Specific Rules for FEUP's Students Assessment. Students will have to take a complementary practical exam (the teacher will specify it, before the day of the exam), where they have to show their knowledge, that couldn’t be assessed during the semester.
According to Article 10 of the Specific Rules for FEUP's Students Assessment.
