Milling cutters for CNC machine tools
Janošek, Martin ; Sámelová, Vendula (referee) ; Humár, Anton (advisor)
My bachelor thesis is about milling cutters for CNC machine tools. First the thesis deals with milling theory. There are fission tools or fission machines. Next chapter is about holding tools. The practical part deals with an assortment of production of milling tools for milling flat surfaces made by three milling tools producers. These are Sandvik Coromant, Pramet Tools and Walter companies. In the end of my work these companies are evaluated from different points of view.

Milling tools for CNC machine tools
Vampola, Lukáš ; Forejt, Miloslav (referee) ; Humár, Anton (advisor)
In this bachelor’s thesis are described milling tools for CNC machine tools. The first part is target the CNC milling machines and CNC machining centres. The main set eyes on tool holder magazines and type of tools for CNC machine tools. In next part of thesis are described milling tools. Description and partition are performed in light of construction, marking, tool materials and using. There are wrote advantage, disadvantage and using tools or material for tools. Re-placeable cutting edges from sintered carbides are most used for milling on the present. Pivotal part of bachelor’s thesis is attended to range of products for milling from renowned producers. I chose Sandvik Coromant and Pramet Tools from many notable concerns.

Application of PVD coatings for milling
Matuška, Martin ; Sedlák, Josef (referee) ; Píška, Miroslav (advisor)
This dissertation treats of the influence of PVD coats to a change of tool lifetime. The theoretical part of the dissertation describes the adjustment of tools before the process of coating. Following part describes the specific properties of deposited layers of the coating and its measuring. There is also the enumeration and specification of selected ways of depositing PVD coats and brief description of its advantages and disadvantages. Second part of the dissertation is focused on an experiment with measuring of the tool force loading and its change depending to the tool wear. There are compared four short four-edged milling cutters with a coat and as well without it. Those tools were made of high speed steel by the conventional way and also by the powder metallurgy. Milling operation was done by down and up milling technique. The evaluation of the experimental results for powder metallurgy tools confirmed that these tools are advantageous compared to the standard high speed steel tools.

Proposal of new clamping system of inserts for wood milling tools
Vančura, Tomáš ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
The work presented in this thesis has been dealt with issues of clamping systems of indexable inserts of woodworking milling tools. The aim of this thesis is to design new clamping system of indexable inserts according to the request of company Vydona, Ltd. The work has been divided into three chapters. Chapter 1 deals with characteristic of wood milling process. It has aimed to create a basic view at main parameters which are influencing clamping system of indexable inserts. Chapter 2 has been a literature search of existing clamping systems used in timber industry. The last chapter has been aimed to design of clamping system for pre-cut indexable insert.

Application CAD/CAM software hyperMILL for machining
Šebesta, Vít ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
The main aim of this thesis is to acquire basic knowledge of CAM program hyperMILL 2019 with comparison of the ball nose end mill and circle segment end mill with taper form, economical evaluation and than make force analysis of specimen from aluminium alloy by milling with spindle moulder. Another aim of this thesis is also an analysis of force effects and force directions of the milling tool, advantages by using the circle segment end mill with taper form, the most common types of aluminium alloys and their mechanical properties and next comparison of CAM program hyperMILL with other selected program in the theoretic part.

Design of the PKD cutting edge cutter
Křehlík, Luboš ; Trčka, Tomáš (referee) ; Polzer, Aleš (advisor)
The thesis deals with the design, construction, production and testing of cutters with polycrystalline diamond cutting edges. Polycrystalline diamond is a suitable cutting material for machining very abrasive materials such as aluminum alloys or composite materials. The design of the tool is focused on the application of the chip breaker on the front of the tool. The aim of the solution is to reduce the cutting force in the machining of the aluminum alloy used in the aerospace industry. The first part of the thesis deals with problems related to milling technology. The practical part describes the design and construction of prototype cutting tools. Three tools were designed for experimental measurement. The technology of cutting tools made from super hardened cutting materials with laser technology is presented. The experimental part of the thesis is a measurement of the cutting force according to cutting parameters and machined material.
