Aim
Chip separation processes are an unavoidable machining method of modern manufacturing technology. The aim of the course is to present the latest developments in addition to the transfer of traditional knowledge. Students will learn about the basics of chip removal, cutting parameters and their effects, the economics of cutting, cooling and lubrication methods, different chip removal methods, and their tools. The tooling systems of the modern production environment are presented in detail. In addition to the basic theoretical knowledge, the main goal is to acquire connections and gain practical experience.

In some situations, as part of a team, you work with your fellow students to solve tasks. He is committed to a systems approach in his thinking. He makes a responsible decision based on the acquired knowledge and self-orientation.
Teaching methodology
During the lectures, the basic definitions and connections related to chip removal will be clarified, the general knowledge related to chip removal will be acquired, and the individual procedures and the tools used in them will be introduced through presentations, demonstration films and writing on the board. During the classroom exercises, a detailed presentation of each sub-area with the help of presentations and writing on a blackboard, problem-solving (computational tasks) in the framework of individual and group work, playing demonstration films, applying presentations, preparing minutes. During the laboratory exercises measurements are done independently and in group work, preparation of protocols.

General rules
In addition to the examination held during the examination period (summary performance assessment), the assessment of learning outcomes is based on active participation in lectures and laboratories (partial performance assessment) and on a diligent task. Attendance at lectures is strongly recommended, 85% of classroom internships and 100% of laboratory internships should be attended, and all minutes should be completed on time in a professionally acceptable quality.
Assessment methods
Detailed description of mid-term assessments
The subject does not include assessment performed during the semester period.
Detailed description of assessments performed during the examination period
Elements of the exam:
| Written partial exam | ||
| Obligation: | mandatory (partial) exam unit, failing the unit results in fail (1) exam result | |
| Description: | A complex, written way of evaluating the knowledge and ability type competence elements of the subject in the form of a dissertation. The dissertation basically focuses on the application of the acquired knowledge, so it focuses on the recognition and solution of the problem, ie in addition to theoretical questions, practical (calculation) tasks must be solved during the performance evaluation. The part of the curriculum on which the assessment is based covers the theoretical knowledge given in the lectures and the skills acquired in the exercises. The available working time is determined uniformly on the basis of the task sequence. | |
| Oral partial exam | ||
| Obligation: | mandatory (partial) exam unit, failing the unit results in fail (1) exam result | |
| Description: | Based on the written result, the final result is formed after the oral questions have been answered. In this section, we assess the more comprehensive picture of the subject and its ability to convey it. The condition for the oral sub-exam is to achieve at least 41% in the written sub-exam. The examining teacher may dispense with the oral questioning on the basis of written performance, but the oral part must also be retained at the request of the student. | |
The weight of mid-term assessments in signing or in final grading
The subject does not include assessment performed during the semester period.
The weight of partial exams in grade
| Type: | Proportion |
|---|---|
| Written partial exam | 100 % |
| Oral partial exam | 100 % |
Determination of the grade
| Grade | ECTS | The grade expressed in percents |
|---|---|---|
| very good (5) | Excellent [A] | above 90 % |
| very good (5) | Very Good [B] | 86 % - 90 % |
| good (4) | Good [C] | 71 % - 86 % |
| satisfactory (3) | Satisfactory [D] | 56 % - 71 % |
| sufficient (2) | Pass [E] | 41 % - 56 % |
| insufficient (1) | Fail [F] | below 41 % |
The lower limit specified for each grade already belongs to that grade.
Attendance and participation requirements
The lack of the value means that there is no attendance requirement.
At least 85% the exercises (rounded down) must be actively attended.
At least 99% of laboratory practices (rounded down) must be actively attended.
Special rules for improving, retaken and replacement
The special rules for improving, retaken and replacement shall be interpreted and applied in conjunction with the general rules of the CoS (TVSZ).
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
| Completion of unfinished laboratory exercises: | ||
| missed laboratory practices must be performed in the teaching term at pre-arranged appointment | ||
| Repetition of laboratory exercises that performed incorrectly (eg.: mistake in documentation) | ||
| incorrectly performed laboratory practice (e.g. Incomplete/incorrect report) can be corrected by repeating the practice | ||
