Course content

The course focuses on the following areas: classification of basic machine parts according to their properties and the complexity of technical systems; connecting and transmission parts, parts of seating, springs, transmission mechanisms, etc; design of small machine part groups both with the help of CAD and without CAD. Lectures: 1. Introduction, aim of the course, prerequisites for granting credit and basic information for the exam. Presentation of design proposals (industrial design) of selected technical products associated with discussions on the possibilities of achieving the required parameters of specified properties (Inventions and discoveries that can change the world. Household appliances for 2020 ... It goes without air. Eternal tire is here!) . 2. Verifying and practicing the ability to create ideas, which is a prerequisite for creative work and an essential part of creating and reading technical documentation. Analysis of causes and consequences of problematic (erroneous) properties of some technical products and design of such corrective design measures to avoid errors or limit their consequences. 3. Rectangular projection, projection methods, rendering. Practical training and demonstration of technical projection on wooden models. 4. Assignment of semestral work. Creating a working drawing (sketch). Search and find similar parts practically used in everyday life of man. Determination of the purpose of use and definition of the function in the semestral work of the solved technical product and processing of a partial technical report.¨ 5. Functional scheme creation and its purpose (demonstration on real drawing from practice). Removal of degrees of freedom by datums. Relationship with fixation of the part in the technical system and prevention of movement of floating tolerance fields. Definition of drawing datums and their meaning. 6. Definition and specification of functional conditions and methods of their provision e.g. by prescribing tolerances for functional dimensions and shapes, position and surface quality of functional surfaces. Demonstration of the problem on the example of a simple pin and desk drawer. 7. Example of creating a functional scheme of a pivot joint fork with cylindrical pin and determination of meaning and importance of individual functional conditions. Description of design and geometric reference elements, functional conditions and design functional elements. 8. Technical drawings and technical terminology, types of lines, drawing scales, technical font. Ways of machine parts representation on technical drawings. Sections, cross-sections, auxiliary views. 9. Dimensioning on technical drawings, dimensioning rules. Dimensioning in terms of function, measurement, production, assembly and optimization of functional conditions. Threading, screw connections. Dimension strings - types and methods of their solution. 10. Tolerancing, single hole system, single shaft system, general tolerances. 11. Presentation of the semestral work and discussion on the presented engineering design proposals and technical solutions - support for inventive solutions. 12. Geometric specification of products. Geometric tolerance. Reference points of construction. Compound tolerance frame. Surface roughness. 13. Technical drawing of machine parts - axle stubs, pins, keys, wedges, shaft elements, bearings, gears, springs, welded, glued and riveted joints.
