Theory of Machining (FSI-HTO)

Academic year 2025/2026
Supervisor: doc. Ing. Karel Kouřil, Ph.D.  
Supervising institute: ÚST all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:

The aim of the course is to provide students with basic knowledge from chip forming processes, evaluation of cutting process experiments and individual relations of cutting processes. In the area of cutting tools students will be made familiar with the designation of cutting planes and cutting angles of one- and multi-edge tools and with their graphical and analytic relations.
The subject familiarises students with the theory of deformation processes while cutting technical materials with various cutting tools. Also dealt with is their experimental evaluation.
