Course detail

CNC Technologies of Machining

FSI-9CTOAcad. year: 2021/2022

The course is focused on advanced CNC manufacturing production. Optimal selection and strategy for machining. Cutting tools, wear and machining parameters. Time consumption and integrity of machined surfaces. Technological routes, for Sinumerik 810D/Heidenhain iTNC530 systems. Optimization of the process from the point of maximum production rate and minimum costs is solved in graphical and numerical ways. Macros, special sub-programmes.

Learning outcomes of the course unit

Students are trained in CNC programming and other aspects of NC machining. They will be able to define technological processes of manufacturing methods and be able to control systems using Sinumerik 810D and Heidenhain TNC 310 in English.

Prerequisites

Successful completion of the courses “Production Technologies II”, “Technology of Production and Computer Support of Technology”, good knowledge of fundamental methods of CNC machining.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline.

Assesment methods and criteria linked to learning outcomes

Examination consists of a written and an oral part. The written part focuses on a solution using CNC programming and machine tooling and settings. The oral part tests student’s knowledge of a topic selected randomly from the concerned areas to assess depth of understanding of the studied processes.

Aims

A study of modern CNC manufacturing technologies. Advanced programming of the Sinumerik 810D control system. Programming of the Heidenhain TNC310 control system. English terminology. Better job opportunities for graduates.

Specification of controlled education, way of implementation and compensation for absences

Recommended participations in lessons. Compulsory and checked participations in exercises and labs.According to the studied topic some lessons will be practicals - carried out in the lab, and some will be focused on the theory - calculations carried out in the classroom in a seminar form. Absence from seminars should be substituted individually by the agreement with the teacher.
