Tools for drilling
Rosa, Jakub ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
This Bachelor's thesis introduces drilling technology, introduces companies which developed drilling tools and production technological experiment of drilling. Bachelor thesis deals with drilling and division drills in the first part. The next part is an overview of several companies, both foreign and from Czech Republic, which designs and manufactures drilling tools. The last parts of the thesis deals with tools selection which were used in technological experiment of drilling into a steel box.

On the cutting performance of selected HSS drills
Med, Slavomír ; Dvořáková, Jana (referee) ; Píška, Miroslav (advisor)
The bachelor thesis aims on a twist drill. In the theorical part characterizes the parts of drill bit and presents its fabrication from fabrication of cutting material to coating. This part finishes by description of contemporary methods of measuring of cutting performance. The main goal of this thesis is to propose and realize measuring of cutting performance of which results we can compare selected HSS drill bits and recommend them to practice. The tests are described in the practical part which contains the evaluation of results too.

On the modern technologies of hole production in metal materials
Laňka, Lubomír ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
This bachelor thesis is focused on the modern technologies for the hole production in metal materials. In the first part the fundamental technologies are described including how to make the hole or to modify it. The second part deals with the modern cutting tools, and the other part includes some machines for hole production. Some non-conventional methods of hole machining are also mentioned. The last two parts deals with the experiments - the tool wear and other phenomena are evaluated when machining some selected materials. The work confirms that the titanium alloy is a material very difficult to drill up today.

Cutting force analysis when drilling with twist drill
Hon, Pavel ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
Theoretical part of this project contains basic characteristics of drilling technology, shows summary of drilling technologies and tools used for drilling, detailed description of twist drill, forces and loads analysis when drill, twist drill stress analysis. In experimental part of this project there are some investigations on twist drill geometry CZ001 made by company NASTROJE CZ, s.r.o. Cutting edge geometry and web thickness is measured on 3D scan of this drill and the results are compared to conventional products. Course of moment of cutting and course of thrust force is done by experiment where the recessed hole was drilled. Course of both loads is compared to long-term results on conventional drills. As application of the achieved results the cutting force position is calculated and stress and deformation analysis is performed.
