Cutting and Cutting tool
Description: The discipline forms a general understanding of engineering and engineering education. The object and subject of engineering are being studied. The discipline reveals the purpose and objectives of engineering education, competencies, knowledge, skills and abilities of a future specialist acquired in the learning process. To achieve the required quality of the machined surface and dimensional accuracy of the parts, it is necessary to correctly assign the cutting modes and the cutting tool.

Teaching methods
By creating the most clear, specific language to describe the learning objectives, into which the teacher can translate insufficiently clear language
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 | РГР-1, 2 | 0-100 |
| 2 rating | РГР - 3,4 | 0-100 |
| Total control | Course Paper | 0-100 |
The evaluating policy of learning outcomes by work type
| Type of task | 90-100 | 70-89 | 50-69 | 0-49 |
|---|---|---|---|---|
| Excellent | Good | Satisfactory | Unsatisfactory | |
| Assessment criteria are the parameters clearly defined in the syllabus, according to which the current, intermediate and final assessment of students is carried out. | Completing tasks of students' independent work for 100-90% | Completing tasks of Independent work of students for 89-75 % | Completing tasks of students' independent work for 70-50 % | Completing tasks of students' independent work for 100-90% |
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 | |
| B- | 2.67 | 75-79 | |
| C+ | 2.33 | 70-74 | |
| C | 2.0 | 65-69 | Satisfactory |
| C- | 1.67 | 60-64 | |
| D+ | 1.33 | 55-59 | |
| D | 1.0 | 50-54 | |
| FX | 0.5 | 25-49 | Unsatisfactory |
| F | 0 | 0-24 |
