FEM for machining simulation
Vojtek, Aleš ; Madaj, Martin (referee) ; Zouhar, Jan (advisor)
The introduction to turning basics, chip separation process, cutting force generation and description of the finite element method. With this knowledge, a cutting simula-tion of AISI 1045 steel was done for 3 different rake angles, which was simplified by using an orthogonal machining model. The next simulation was cutting of AISI 6150 steel with the use of a 3D model of the grooving insert. The results of these simulations were then compared to the experimental results, and feasibility of finite element method was determined together with future recommendations for acquiring more pre-cise results.

Cemented carbide tool materials
Bil, Miroslav ; Humár, Anton (referee) ; Kalivoda, Milan (advisor)
Main goal of this bachelor thesis is the introduction with characteristics of tool materials and assessing their fitness for use in machining operations. The thesis also deals with the parting-off tools, blade geometry issues, a general overview of the tool material group of cemented karbide cutting tools and their properties. There is a mention of overview of companies and world development.
