Design of semi-automatic tool for thread machining on conventional lathe
Ondák, Andrej ; Klapka, Milan (referee) ; Dočkal, Kryštof (advisor)
Design of thread cutting rig reducing demands on machine operator of conventional lathes is shown in the following thesis. During thread cutting on lathe, operator must execute cutting tool extraction, stopping of the machine, and changing direction of the spindle in the span of few seconds. The design of an auto-retracting tool solves the problem by automatization of these steps of the production process. Therefore, three tool concepts were proposed differing in the cutting tool pull-out mechanism. One solution was chosen, whose function was substantiated by calculation. Reader can acquaint himself with construction idea behind this auto retracting tool for thread cutting. Among other things, reader can explore problems encountered during the process of the construction and its engineering solutions.

Threading operations in the building industry
Čech, Ondřej ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
The aim of this bachelor thesis is the sumarization of common threads and thread joints used in construction industry complemented with illustrations of actual joints. On construction thread cutting possibilities, more precisely situations, where there is no possibility to use stanionary placed machinery. Mechanical engineering machinery overwiev. Technological regime of selected thread joints. This thesis is supplemented with description of specific machining and thread cutting work on heavy-duty part of hydropower plant.

Formed and Machined Threads on Products from Sheet Metal in Company European Data Project s.r.o.
Hořava, Lukáš ; Chladil, Josef (referee) ; Kalivoda, Milan (advisor)
The object of the bachelor thesis is the method of chip and non-chip production of threads determined for mainly metal products. The first part is focused on the products which have been producing by company EDP, s.r.o. Further, the individual thread types, the most common methods of their production and the methods used in the company are mentioned. In the following experimental part, the production of samples with shaped threads and machined threads are described. The attention is also dedicated to the adventiges, and disadventiges of the methods used by the company, as well as the economic appreciation. The conclusion is made of proposal of the thermal drilling and its evaluation.

On the modern technologies of thread production
Mišák, Ondřej ; Dvořáková, Jana (referee) ; Píška, Miroslav (advisor)
This bachelor's thesis deals with the study of threads, specifically the introduction to the basic geometry of threads, their production and modern trends by which threads can be made. The experimental part is devoted to the production of threads using cutting and forming taps, comparison of force and moment loads and damage caused during the production of threads when changing the cutting speed. In the end, the achieved results of experimental tests and their evaluation are summarized.

The purpose of design for hand tools
Remeš, David ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
This thesis deals with the effect of the design on hand tools. In the first theoretical part of this thesis, individual manual operations carried out during manufacturing are being further analyzed. The next part then focuses on the individual aspects of the product design and its influence on the hand tools. Followed by the processing of achieved parameters in handwork. The experimental part of this thesis deals with adjustments of the tap wrench´s handles made for manual cutting of internal threads. The utilization of the material when selecting a semi-finished product from blanks as well as the evaluation of the manufacturing in this way itself are also closely described in this part.
