Aim
The course introduces students to the structural elements (eg. actuators, guideways, servomotors, measuring devices, etc.) and different types (eg. lathes, milling machines, grinding machines, machining centres, etc.) of metal-cutting machine tools and their technological and operational characteristics. Also, the course introduces the basic concepts, types and layouts of manufacturing systems and the most important material handling equipment needed to build manufacturing systems (e.g. conveyors, AGVs, robots, etc.).
Learning outcomes
Competences that can be acquired by completing the course
Knowledge
The students are aware of the motion system of machine tools, their main units, CNC integration. The students are informed about the guideways of machine tools (sliding, rolling and hydrostatic guideways). The students know the linear drives (ball screw, linear motor, rack and pinion). The students know the rotary drives (worm, gear, torque motor). The students are aware of the different types, structural and technological characteristics of drilling and milling machines as well as CNC machining centres. The students are aware of lathe-like machine tools (universal, mechanically program-controlled, CNC lathes and CNC turning centres), their structural and technological characteristics. The students are aware of the different types, structural and technological characteristics of grinding machines and EDM machines. The students are aware of the different types, structural and technological characteristics of multifunctional and hybrid machine tools. The students know the basics of production logistics, the principles of material handling. The students are familiar with the types and constructions of intermittent material handling equipment. The students are aware of the types and constructions of continuous material handling equipment. The students are aware of the types of manufacturing systems, the types of manufacturing system layouts.
Ability
The students identify the main units of machine tools, parts of CNC integration. The students select the guideways of the machine tools (sliding, rolling and hydrostatic guideways). The students select the elements for linear drives (ball screw, linear motor, rack and pinion). The students select the elements of the rotating drives (worm, gear, torque motor). The students use what they have learned about the different types, structural and technological characteristics of drilling machines, milling machines and CNC machining centres. The students identify lathe-like machine tools (universal, mechanically program controlled, CNC lathes and CNC turning centres), their structural and technological characteristics. The students identify the different types, structural and technological characteristics of grinding machines and EDM machines. The students learn about the different types, structural and technological characteristics of multifunctional and hybrid machine tools. The students interpret the basics of production logistics, the principles of material handling. The students use what they have learned about the types and constructions of intermittent material handling equipment. The students use what they have learned about the types and designs of continuous material handling equipment. The students use what they have learned about the types of manufacturing systems, the types of manufacturing system layouts.
Attitude
The students are open to collaboration with the instructor and fellow students as they expand their knowledge. The students expand their professional knowledge constantly. The students are open to the use of information technology tools. The students seek to become familiar with and routinely use the tools required to solve problems. The students strive for an accurate and error-free solution.
Independence and responsibility
The students independently think through tasks and problems and solves them based on specific resources. The students accept well-founded professional and other criticisms. In some situations, as part of a team, the students work with their fellow students to solve tasks. With their knowledge, the students make a responsible, well-founded decision based on their analyses. The students feel responsible for the design and operation of machine tools and manufacturing systems.
Teaching methodology
The teaching of the subject consists of lectures. The lectures basically introduce students to the information defined by the knowledge competence elements using the technique of frontal education. The slide shows used in the lectures can be downloaded from the online source of the subject. The presentations focuses primarily on machine tools, material handling equipment and manufacturing systems for metal cutting technology. Written performance assessments are held at equal intervals throughout the semester. Instructors are open for personal consultation if students request it.

General rules
As the course only includes lectures, participation to 70% of the lectures are compulsory. The three written performance assessments are held in the 5th, 9th and 14th weeks of the semester. The performance assessments assess the knowledge and skill competencies acquired during the lectures. Written performance assessments are closed book tests. At least 40% must be reached at all three performance assessments.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | summative assessment | |
| Number: | 1 | |
| Purpose, description: | The first summative performance assessment will take place in the 5th week of the semester. The form of summative performance assessment is a closed book written test. The test assesses the acquisition of knowledge and skills learned during the first four lectures. The performance assessment requires the completion of 40% of the maximum achievable score. It is possible to retake the performance assessment during week 5 or 6 (one repeat). | |
| Mid-term assessment No. 2 | ||
| Type: | summative assessment | |
| Number: | 1 | |
| Purpose, description: | The second summative performance assessment will take place in the 9th week of the semester. The form of summative performance assessment is a closed book written test. The test assesses the acquisition of knowledge and skills learned during the lectures after the first performance appraisal. The performance assessment requires the completion of 40% of the maximum achievable score. It is possible to retake the performance assessment during week 10 or 11 (one repeat). | |
| Mid-term assessment No. 3 | ||
| Type: | summative assessment | |
| Number: | 1 | |
| Purpose, description: | The third summative performance assessment will take place in the 14th (last) week of the semester. The form of summative performance assessment is a closed book written test. The test assesses the acquisition of knowledge and skills learned during the lectures after the second performance appraisal. The performance assessment requires the completion of 40% of the maximum achievable score. It is possible to retake the performance assessment during the additional week (one repeat). | |
