Course detail
Special Technology of Machining
FSI-HO1-K Acad. year: 2021/2022 Winter semester
The course is focused on the machining technology used with numeric control machine tools. Students will obtain basic knowledge of programming NC-machines, they will familiarise with the use of linear programming in the technology, especially for determining optimum cutting parameters, with solution of dimensional chains in TPV applying methods of mathematical statistics, theory of operating allowances, and with conventional, as well as prospective cutting tools used with NC-machines. Practical exercises are carried out on CNC educational machine tools and PCs, used especially for a simulation of the machining at NC- machines and solving of linear programming tasks.
The subject is directed to the machining technology on CNC machine tools. The students are given the basic knowledge in the programming of NC machine tools such as linear programming in technology, especially for determination of optimum cutting parameters, solution of dimensional chains with the application of mathematical statistics methods. Practical exercises are realised on CNC machine tools and PC especially by simulation

Learning outcomes of the course unit
The students will obtain theoretical fundamentals of a machining technology with the use of numeric control machine tools, they will learn basic methods of programming of these tools, and will be acquainted with economic aspects of technological disciplines.
Prerequisites
The fundamentals of the metal cutting theory, probability theory, differential and integral calculus, determinants, dynamic of the mass point, mechanical work and energy, molecular physics and thermodynamics
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes
Credit requirements include an active participation in all exercises, completing all tasks in the laboratory exercises, and delivery of all required written work. In well-founded cases the teacher can set further conditions as a compensation. The examination tests the knowledge and, in particular, the ability to apply the knowledge independently in solving assigned tasks. The examination consists of a written (test or written exam) and oral part. If the student fails to apply the knowledge in practice, the examination will be graded as unsatisfactory.
Aims
The aim of the course is to familiarise students with automation of a short-run and single-part production focusing on an application of numeric cntrol machine tools including technical production planning.
Specification of controlled education, way of implementation and compensation for absences
Students work is systematically controlled in a form of short written tests, individual compensatory assignments and result check.
