Production technology of drill
Křehlík, Luboš ; Kolář, Ladislav (referee) ; Osička, Karel (advisor)
The work deals with production technology stepped drill of cemented carbides. Handles the basic methods and information technology grinding. Cemented carbides are becoming more frequent choice of material for processing in many industrial directions. They allow widespread use due to their mechanical and technological properties. Tools of this material are manufactured on a 5-axis grinding machines. The use of precision CNC machines enables efficient and accurate production of both simple and complex cutting tools. Software CNC machines allow you to control the 3D simulation before production begins, it's a convenient tool for checking the functionality of the program. It is also possible to establish the production of the subsequent dimensional control of the finished piece. These CNC machines and cemented carbide tools can be used for both serial and piece production.

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.
