Aim
One of the main aims of teaching the subject is to acquaint students with machining methods whose development dates back up to a few decades but are already unavoidable in modern manufacturing technology (e.g. laser beam machining, water jet cutting, EDM). The methods can be used to machine parts and structures of micro-size, extremely high dimensional accuracy, excellent surface quality, special geometry, etc., but they can also often be considered as an economical alternative to traditional technologies. In addition to the above, technologies for the production of special geometries are also discussed.

It publishes its opinions and views without offending others.
Independence and responsibility
Collaborates with the instructor and fellow students to expand knowledge. Accepts well-founded professional and other critical remarks. In some situations, as part of a team, you work with your fellow students to solve tasks. With his knowledge, he makes a responsible, well-founded decision based on his analyzes. He feels a responsibility for production economy and sustainable development. He is committed to the principles and methods of systematic thinking and problem solving.
Teaching methodology
The teaching of the subject takes place in the framework of lectures and laboratory practice. The lectures basically introduce the students to the information determined by the knowledge competence elements using the technique of frontal education. The application and skill-level acquisition of knowledge takes place in laboratory exercises, where an issued project work has to be solved in groups, which also develops teamwork skills.

General rules
Learning outcomes are assessed on the basis of two mid-year written summary performance measures. Summative academic performance appraisal is a complex, written way of assessing the knowledge and ability type competence elements of a subject in the form of an in-house dissertation, which requires the necessary lexical knowledge during the performance appraisal, the available working time is 60 minutes. Partial performance evaluation (protocol): a complex way of evaluating the knowledge, ability, attitude, and competence and responsibility type competence elements of the subject, the form of which is a report-type protocol of laboratory exercises.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | summative assessment | |
| Number: | 2 | |
| Purpose, description: | Summative assessments collectively examine and assess students ’learning outcomes defined by knowledge and ability type competencies. Accordingly, each summative assessment assesses the acquisition of the designated theoretical knowledge as well as the existence of the knowledge and skills acquired in practice. Each summative assessment focuses 65% on theoretical knowledge and 35% on application skills. They will be completed on the date specified in the academic performance assessment plan, scheduled for the 7th and 14th weeks of education. 80 points can be obtained in the summary performance evaluation. A minimum of 41% should be achieved on each. | |
| Mid-term assessment No. 2 | ||
| Type: | formative assessment, simple | |
| Number: | 2 | |
| Purpose, description: | The evaluation of the measurements performed in the laboratory exercises of the subject forms the basis of the partial performance evaluations. The experiments performed must be in the form of a report. The minutes shall be attached to the report. Criteria for evaluating the report include content, engineering language, layouts, and applied engineering solutions. The formal requirements for the report vary from laboratory to laboratory. The expectations are set by the head of the given laboratory practice. | |
Detailed description of assessments performed during the examination period
The subject does not include assessment during the examination period.
The weight of mid-term assessments in signing or in final grading
| ID | Proportion |
|---|---|
| Mid-term assessment No. 1 | 80 % |
| Mid-term assessment No. 2 | 20 % |
The weight of partial exams in grade
There is no exam belongs to the subject.
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
Must be present at at least 70% (rounded down) of lectures.

| Need mid-term assessment to invidually complete? | ||
| yes | ||
| Can the submitted and accepted partial performance assessments be resubmitted until the end of the replacement period in order to achieve better results? | ||
| NO | ||
| The way of retaking or improving a summary assessment for the first time: | ||
| each summative assessment can be retaken or improved | ||
| Is the retaking-improving of a summary assessment allowed, and if so, than which form: | ||
| retake or grade-improving exam possible for each assesment separately | ||
| Taking into account the previous result in case of improvement, retaken-improvement: | ||
| new result overrides previous result | ||
| The way of retaking or improving a partial assessment for the first time: | ||
| partial assesment(s) in this group cannot be improved or repeated, the final result is assessed in accordance with Code of Studied 122. § (6) | ||
| Completion of unfinished laboratory exercises: | ||
| missed laboratory practices may be redeemed by alternative partial assessment by the end of the retake period | ||
| Repetition of laboratory exercises that performed incorrectly (eg.: mistake in documentation) | ||
| incorrectly performed laboratory practice (e.g. Incomplete/incorrect report) can be corrected upon improved re-submission | ||
