Production of steel structures of halls
Ondráček, Pavel ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
Bachelor thesis deals with the production of steel constructions of halls in a complex way. The introductory chapter introduces the advantages and disadvantages of steel constructions, their basic distribution, individual types of constructions and their parts. The following chapters describe the individual phase production of steel constructions of halls, from initial design and negotiations with the investor, through preparation of production, production itself, to final assembly. In the production process are described possible variants of the methods used. Description of the assembly procedure is complemented by the most common cover elements of the hall. The practical part describes the production and installation of a specific steel construction in a selected production plant. The part of the bachelor´s thesis is also the issue of budgeting with indication the individual items that affect the final price of the contract.

Production technology of milling head spindle
Měrka, Tibor ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The aim of the diploma thesis is a milling head spindle heat treatment and production technology of this part. The introductory section of the thesis covers tasks of milling head spindle and required properties. Also includes overview of most-known types of heat and chemical treatment and milling head spindle production technology process proposal, which presents in more detail nitrocarburizing process called ARCOR V. Experimental part of the thesis gives consideration as well to the liquid salt bath nitrocarburizing application on different material samples and assessment of nitrocarburized material for this heat treatment process. The result of the thesis is spindle production technology process description with application of nitrocarburizing ARCOR V and also determination of suitability of selected materials for this surface treatment method and it’s practical applications.

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.

Suggestion for rationalization of injection mould part production
Kamenická, Eva ; Kalivoda, Milan (referee) ; Sedlák, Josef (advisor)
The diploma thesis deals with suggestion for rationalization of production of an injection mould cavity plate and of a part responsible for cooling of the final plastic product. The main objective is to reduce the production time while meeting the high requirements for dimensional and geometric accuracy and surface integrity of the manufactured parts. The thesis starts with a theoretical analysis of the production of mould parts. This is followed by an analysis of the initial state of production, which consists of the characteristics of the previously mentionned manufactured parts, the available production means and a description of the original technological process. The experimental part of the thesis explains the procedures and justifies the choices made in the creation of new programmes within the CAM software Cimatron. Several possible variations of tools and cutting parameters have been experimentally tested and their final choice is justified in the thesis. The output of the thesis is a new manufacturing process for the production of both components, which has been applied in practice and evaluated on the basis of the results of testing the quality of the components and the plastic product itself. In the conclusion of the thesis can be found an evaluation of the output of the thesis and a time comparison of the previous process with the new suggestion. All experiments and measurements, including the production of the components themselves, were carried out in the toolroom of ITW PRONOVIA, s.r.o. in Veľká Bíteš, which is also the creator of the topic of this thesis.

Use of water jet technology in a company
Faltus, Tomáš ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
This thesis focuses on water jet technology. In the theoretical part of the thesis, the principle and classification of this technology, the quality of the cut surfaces after water jet cutting, the types of bevels, and the equipment needed for this technology are described and analyzed. It also describes the use of an abrasive water jet in machining and summarizes the advantages and disadvantages of this technology. Additionally, the thesis presents the machinery of the company with which the author of the diploma thesis worked, as well as its production range. The practical part of the work is devoted to the experiment, which consists in selecting a component for the production of samples using two abrasive nozzles, with subsequent assessment of the quality of the machined surfaces in relation to the size of the diameter of the abrasive nozzles as well as in relation to the materials and their thickness. Two materials of two different thicknesses were used for the samples. The quality of the machined surfaces was measured using two roughness meters. The average arithmetic deviation of the profile Ra and the largest height of the profile Rz were measured. At the end of the thesis, the deflection of the beam is measured using a microscope, and the consumption and the price of the abrasive for individual sample components were also calculated.
