Course detail

Special Technology of Machining

FSI-HO1Acad. year: 2011/2012

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

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

Credit requirements include an active participation in the 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 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.
