Course abstract

The aim of the course is to develop the geometric logic, spatial thinking and imagination of the concepts that form the content of the course. Learn how to use graphic techniques. To teach to make and read drawings what is the international graphic language and a means of creative thinking. To promote the use of standards (LVS, ISO, etc.) in the design of technical documentation.

Learning outcomes and their assessment

Knowledge –students understands the drawing projection method, the principles of creating views and sections. Knows the standards related to drawing design (ISO, LVS, GOST, etc.). Knows the types of products and the corresponding work documentation and the sequence of its execution. Orients the information included in the engineer drawing about dimensions, indications about threads, surface roughness and material - 1st test and laboratory work.

Skills - is able to perform sketches, parts and product drawings, draw up mechanical drawings of parts, make assembly drawings of disassembled and non-disassembled joints and compile the corresponding documentation. Is able to read and compile assembly and detail drawings in accordance with LVS, EN, ISO, GOST, etc. standard requirements - 1st and 2nd homework, 2nd test and laboratory work.

Competences - is able to use the acquired professional knowledge and drawing skills in studies, practical work and implementation of creative thought. Able to independently develop and adjust product design solutions and compile the necessary documentation - 1st and 2nd homework, laboratory work.

Course Content(Calendar)

1.1. Geometrical constructions (Laboratory works - 2h).
2. Orthographic views. Axonometric (Laboratory works - 2h).
3. Principles of dimensioning (Laboratory works - 1h).
4. Sectional views. Full, half and auxiliary sectional view (Laboratory works - 2h).
5. Offset, revolved, aligned, removed and broken sectional views (Laboratory works - 1h).
6. 1.Test work: designing the third view based on the two given, necessary sectional views (Laboratory works - 1h).
7. Representation of threaded parts (Laboratory works - 2h).
8. Sketching parts (Laboratory works - 2h).
9. Types of drawings. Bill of materials (Laboratory works - 2h).
10. Assembly drawing (Laboratory works - 4h).
11. Reading and detailing of assembly drawings (Laboratory works - 2h).
12. Axonometric views (Laboratory works - 2h).
13. 2.Test work: details drawing (Laboratory works - 1h).

Requirements for awarding credit points

A test with a mark is formed as follows:
• developed and successfully presented laboratory works (80%);
• successfully passed tests (20%).

Description of the organization and tasks of students’ independent work

The tasks set in the laboratory works must be completed independently, in accordance with the conditions specified in the laboratory work. Presentation of the work takes place after its completion, during laboratory work.
1st homework - Representation of threaded parts.
2nd homework - Details drawing from assembly drawing.

Individual independent practical studies, in-depth study of test topics.

Criteria for Evaluating Learning Outcomes

The evaluation of the study course test depends on the cumulative evaluation of the study course laboratory work, homework and tests.
The test mark is calculated as the arithmetic mean of two tests and the average semester mark, which is calculated as the arithmetic mean of the marks of laboratory work and homework taken in the study course.
A student obtains a successful grade for laboratory work and two homeworks if the work is presented and at least 40% of the conditions for the development of work are met.
A student obtains a successful grade for a test if at least 60% of the tasks have been solved correctly.
