Aim
The aim of teaching the course is to acquaint students with the basic theoretical and application issues of NC technology, the control and programming possibilities of equipment, and the programming of numerically controlled machine tools. They gain proficiency in manufacturing preparation, component manufacturing, and NC machine management, as well as modeling and programming the sequence control tasks of these machines.

Open to the use of information technology tools. 4. Seeks to become familiar with and routinely use the toolkit needed to solve the problem. 5. In the course of his work, he is open to the implementation of accurate and error-free task solutions.
Independence and responsibility
1. Independently thinks through tasks and problems and solves them based on specific resources. 2. Collaborates to improve substantiated critical remarks. 3. In some situations, as part of a team, you work with your fellow students to solve tasks. 4. The sub-task assigned to it by the measuring group is performed independently and responsibly. 5. Take responsibility for the content and quality of the minutes submitted by the group.
Teaching methodology
During the teaching of the subject, the lecture and practice are separated from each other, both in terms of content and methodology. The lectures basically introduce students to the information defined by the knowledge competence elements using the technique of frontal education. The lectures have pre-published slide shows, so students can add their own notes to the lecture. The lectures are complementary to the main (on-line) written study materials, and are not sufficient to achieve adequate preparation. Independent practical sessions promote the application and skill-level acquisition of knowledge with a different theme from the lectures and the method of the mirrored classroom. During the exercises, the knowledge previously acquired at home and independently is solved partly jointly and partly individually with the help of the practice leader. Design exercises include designing part programs (NC programming) and writing sequential controls (PLC programming).

General rules
A 2.2. The assessment of the learning outcomes set out in point 1 is based on two mid-year written performance measurements (two summative academic performance assessments), a design homework assignment (partial performance assessment) and active participation in exercises and laboratories. Summarizing academic performance evaluation: a complex, written way of evaluating the competence-type competence elements of the subject and knowledge in the form of an indoor dissertation, the dissertation focuses on the application of the acquired knowledge, so it focuses on problem recognition and solution, on the other hand, asks for the necessary lexical knowledge during the performance appraisal, the working time available is 90 minutes; Partial performance evaluation (homework): a complex way of evaluating the knowledge, ability, attitude, and autonomy and responsibility type competence elements of the subject, the form of which is individually prepared.
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 evaluation plan, expected to be in the 7th and 12th weeks of education. Each of the two summary performance evaluations can earn 100-100 points. | |
| Mid-term assessment No. 2 | ||
| Type: | formative assessment, point-in-time personal act | |
| Number: | 1 | |
| Purpose, description: | The basic goal of partial performance evaluation is to solve a project-type task independently. During the project task, the modeling and programming of synchronous control of cyber-physical systems must be solved. You must document the functional plans for solving project tasks and demonstrate the correct operation of the program using a cyber physical simulator system. 100 points can be obtained in the partial performance evaluation. | |
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 | 60 % |
| Mid-term assessment No. 2 | 40 % |
The condition for signing is that the score obtained in the mid-year assessments is at least 50%.
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] | 85 % - 90 % |
| good (4) | Good [C] | 72 % - 85 % |
| satisfactory (3) | Satisfactory [D] | 65 % - 72 % |
| sufficient (2) | Pass [E] | 50 % - 65 % |
| insufficient (1) | Fail [F] | below 50 % |
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 70% the exercises (rounded down) must be actively attended.
At least 85% 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).
| Need mid-term assessment to invidually complete? | ||
| yes | ||
| 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 not possible | ||
| 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 performed in the repeat period, non-mandatory | ||
| 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 | ||
