Course abstract

The aim of the study course is to study the geometric forms and relationships of the surrounding environment, to find out the relevant regularities and to apply them in solving its practical tasks, to develop geometric logic, spatial thinking and to visualize 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 techn

Learning outcomes and their assessment

Knowledge - understanding of spatial projection methods of elements. Orients in the construction of geometric elements, objects and their layouts. 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 in the information included in the drawing about dimensions, indications about threads, surface roughness and materials - 1st test and laboratory works.

Skills - is able to practically apply the standards set by the food industry, is able to choose the necessary methods for solving tasks and perform technical documentation. Is able to perform sketches, parts and product drawings, draw mechanical drawings of parts, make assembly drawings of disassembled and non-disassembled connections and compile the corresponding documentation. Is able to read and compile assembly and detail drawings in accordance with LVS, EN, ISO, GOST, etc. standards requirements - 1st and 2nd homework, 1st test and laboratory works.

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 and laboratory works.

Requirements for awarding credit points

The final mark consists of:
• developed and successfully presented laboratory works (80%);
• successfully passed test (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.
1.homework – Representation of threaded parts.
2.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.
