Engineering Graphics

Lectures

Goal

The goal of the course is that students master the skills necessary for successful viewing (and reading) of machine parts components technical drawings. The student should know all the rules and standards that are used for formating, dimensioning and defineing of the machine parts machining on the drawings.

Outcome

The outcome of this course is the students' ability to model mechanical parts as well as their assemblies by the using of the software package SolidWorks. Moreower, it is necessary to show the assemblies and parts on drawings with the appropriate sections so that they can be fully formally, dimension and machining defined.

Theoretical teaching

Drawing in Mechanical Engineering; displaying objects in the drawing; composition parts, pictures of objects. Axonometric projection of objects and their interpretation. Views; basic views; separate views; types of lines in mechanical engineering. Sections, a complete crosssection; half cross-section, partial cross-section, labeling section; profile sections. Breakthroughs; symmetrical parts, repeated details. Dimensioning; function wheel; elements of Dimensioning; marking point on the drawing; methods quotation. Threads display; coil; threaded double and tags for loops. Marking sheet surface; surface roughness; means for quality of workmanship, labeling on the drawings. Technical Letter; scale, the formats, headers and components; positional label elements. Gear display; Springs display; Welded seams display. Shape and position tolerances.

Practical teaching

Axonometric sketching and 3D modeling of simple machine part, displaying the same model in three main views. Presentation of machine parts by imaginary sections in three major orthogonal views. Preparation 3D model of a given machine part; making technical drawings in sufficient numbers of views using the imaginary section; the using of special views and sections; dimensioning part of the drawing. Molding of all parts of the given assemblies; creating the production drawings in sufficient number of views with appropriate labeling and providing a measure of dimensions, making components, filling tables in the drawing, drafting workshop drawings for at least three part of the circuit which are connected together; numbering workshop drawings in accordance with the numbering of the assembly. Creating 3D model for three possible models for the (complex) mechanical parts, development of appropriate technical drawings in a sufficient number of views, using reflective section; application of particular views and cross sections; dimensioning; indication the quality of roughness. All exercise assignments are done either directly, bu the using of drawing tools or by the using of suitable and appropriate software applications, such as SolidWorks is.
