Design of bench drill
Štěrba, Jakub ; Marek, Tomáš (referee) ; Pavlík, Jan (advisor)
The aim of the work is a bench drill structural design. The first part describes drilling machine categories, compares some of drill press machines available on the market and lists main flaws of most drilling machines on the market. In the second part the basic concept is selected and the actual design of the individual components of the drill is performed. The third part contains selected strength and kinematic calculations. In the last part, the final model of the machine is presented, and the current production progress is discussed.

Passive compensation of a thermal deformation for a machine tool
Šabart, Adam ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
This master thesis deals with passive compensation of a thermal deformation for a binder of portal machining center. The problem is solved by computational modeling with finite element method using ANSYS Workbench software. Afterwards mathematical optimization (also using ANSYS Workbench software) is used for finding binder parameters in order to reduce thermal deformation and its weight. The output is two new versions of binder which are compared to the original configuration.

Economic comparison of manufacturing the machine parts on machine tools in the company Frentech Aerospace s.r.o
Novák, Lukáš ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
Bachelor thesis deals with economic assessment of three different methods of production a given part. Two methods of production are given by Frentech Aerospace s.r.o. The third method is designed to lower the final price of the component. Machines are selected from the offer of Mazak machines in the new manufacturing process. Developing of program for manufacturing workpiece on machine tools belongs to this thesis. The goal is to upgrade the existing method of production the specified component. Bachelor thesis is concluded technical-economic evaluation of all three alternates.

Design of rotary table with maximal load capacity 65 000 kg
Bezděk, Petr ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
The diploma thesis deals with the design of a rotary table for machining large non-rotary workpieces up to a maximum weight of 65 000 kg. The aim of the work is to analyze and evaluate the current state of knowledge in the field of rotary tables, to create a table design according to the assignment and its 3D model with part of the drawing documentation. The theoretical part of the work searches for solutions used in the construction of rotary tables in the category of table according to the assignment. The information obtained is further used in the design of rotary table solution variants. By evaluating the weight of the required properties and their degree of fulfillment, a variant of the design solution of the table is selected, which is then designed. The individual design steps are described and explained in the text part of the work accompanied by pictures and calculations. The result of the process is a structural design of the mechanical part of the rotary table with a 3D model and partially processed drawing documentation. The contribution of the work is the summarization of relevant information for the design of rotary tables, the processed procedure of solving the design of the table and the modeled design of the rotary table. These outputs can be further treated as documentation for the production of the designed table, the development of the rotary table design to deeper details or technical development in this area.

Analysis of kinematics of a ball screw mechanism
Sladký, Adam ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
This thesis describes the process of creating a mathematical model of the kinematics of a ball screw, based upon which a computational model was made, along with an intractive Matlab user interface that serves to provide fast analysis of some of the most important parameters of the mechanism. Functionality of the presented model was verified using specific ball screw parameters. The output of this analysis was presented, analysed, and results describing the influence of operating conditions on the mechanism were derived from it. These results are one of the outputs of this thesis. Both the mathematical and computational models can serve as a tool for ball screw designers and manufacturers, and not only in their current state. They can also provide a starting point for anyone that requires a kinematic analysis for a specific configuration or problem.
