Qualimetry and technical measurements
Description: The discipline studies qualimetry and technical measurements. Students analyze the geometric parameters of parts and the characteristics of their surfaces as physical quantities, accuracy grades, fits in the joints of parts, and their interchangeability. Students study the methods of their measurements, evaluate the suitability of measuring instruments based on qualimetric characteristics and the accuracy of measurement results

Goal
- mastering the methods of qualimetry and metrology, acquiring knowledge in the field of product and process quality assessment and management, as well as developing the skills to carry out technical measurements using modern measuring equipment and techniques, ensuring the reliability and accuracy of the results obtained.
Objective
- Formation of students' professional competencies necessary for conducting quantitative and qualitative assessment of products, processes and services using qualimetry and technical measurement methods, as well as developing skills in analyzing, interpreting and using measurement results to make managerial decisions in the field of quality.
Learning outcome: knowledge and understanding
- The student possesses knowledge and understanding of the fundamental principles, methods, and tools of qualimetry and technical measurements. They are familiar with the classification and characteristics of measurement systems, can analyze the accuracy and reliability of measurements, and apply methods for evaluating the quality of products and processes based on quantitative indicators.
Learning outcome: applying knowledge and understanding
- The student is able to apply the acquired knowledge and understanding of the principles, methods, and tools of qualimetry and technical measurements to solve practical tasks related to the evaluation of product and technological process quality, selection and use of measurement systems, as well as analysis of the accuracy and reliability of measurement data.
Learning outcome: formation of judgments
- As a result of mastering the discipline, the student has developed an understanding of the principles of quantitative quality assessment, methods of technical measurements, and analysis of the metrological characteristics of measuring instruments. The student is capable of reasonably evaluating the accuracy, reliability, and objectivity of measurement data and applying qualimetry methods to make informed engineering and technical decisions in professional practice.
Learning outcome: communicative abilities
- As a result of mastering the discipline, the student has acquired communication skills necessary for clearly and convincingly presenting measurement results and quality assessments, effectively collaborating with colleagues in discussing measurement methodologies, interpreting data, and making technical decisions, as well as formulating conclusions accurately in both oral and written form
Learning outcome: learning skills or learning abilities
- Able to independently study and apply methods of qualimetric evaluation of the quality of products, processes, and systems based on regulatory documentation and scientific literature
Teaching methods
The following educational technologies are intended to be used during the learning process: Under the credit-based learning system, classes should be conducted primarily in active and creative formats. Among the effective pedagogical methods and technologies that promote student engagement in knowledge discovery and management, as well as the development of independent problem-solving skills, the following should be highlighted: problem-based and project-based learning technologies; research-based learning technologies; communicative technologies (such as discussions, press conferences, brainstorming sessions, academic debates, and other active methods and formats); the case method (situation analysis); game-based technologies, including participation in business, role-playing, and simulation games; information and communication technologies (including distance learning technologies).
Assessment of the student's knowledge
Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.
| Period | Type of task | Total |
|---|---|---|
| 1 rating | Current survey on lectures. Test assignments based on handouts. Attendance. | 0-100 |
| Measurement of cylindrical parts using a caliper, conclusion on suitability based on dimensions and form deviations. | ||

Evaluation form
The student's final grade in the course is calculated on a 100 point grading scale, it includes:
- 40% of the examination result;
- 60% of current control result.
The final grade is calculated by the formula:
| FG = 0,6 | MT1+MT2 | +0,4E |
| 2 |
Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;
E is a digital equivalent of the exam grade.
Final alphabetical grade and its equivalent in points:
The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
| Alphabetical grade | Numerical value | Points (%) | Traditional grade |
|---|---|---|---|
| A | 4.0 | 95-100 | Excellent |
| A- | 3.67 | 90-94 | |
| B+ | 3.33 | 85-89 | Good |
| B | 3.0 | 80-84 | |
