Production form-parts by cutting
Hansen, Petra ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The thesis elaborated in an undergraduate degree in Manufacturing Technology, proposes a technology for cutting form parts. The specified component is made from 3 mm sheet metal. The material component is structural steel EN S235JRG1. Based on the literature study, several possible methods of production parts are described. After evaluation of the required accuracy, surface quality and yearly volume of production (100 000 units / year) the technology of fine blanking has been chosen. For the production of components will be used: Triple hydraulic press, HFA 3200plus, made by Feintool. Cutting tool has been designed with moving punch, and the tool contains standardized parts. The economic comparison has been made between the methods of precision cutting, trimming and unconventional classic laser technology.

Forming Technology of Thin Sheets with Coating
Procházka, Lukáš ; Schwarzer, Emil (referee) ; Dvořák, Milan (advisor)
The bachelor's thesis deals with forming technology of thin sheets with coating. It is divided in three separate parts. Firstly, technologies used for forming thin sheets with coating like bending, drawing, spinning and shearing are discussed. Secondly, the thesis presents coatings, their types and means of measuring their thickness as well as examination technologies. The last part consists of a set of experiments testing aforementioned facts on testing samples.

Design forming tool for production of cylindrical case
Fiedor, Pavel ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The project was made as a part of a bachelor’s degree study program B-STG and it proposes the concept of a molding instrument for the making of a headless bushing. The making of the given part consists of 3 operations, including widening by means of a hard instrument and flanging. The instrument is fastened into a hydraulic press CUPJ 60/10. The cutting method is used in order to prepare the semi-product. The aim of the bachelor’s thesis is to propose a technological procedure of making and processing of design documentation of an instrument for making a headless bushing.

Technology of emitter production
Šrotíř, Petr ; Císařová, Michaela (referee) ; Dvořák, Milan (advisor)
The goal of this bachelor thesis is to compare the technologies of production of given workpiece using the technology of spinning and deep drawing. The object of this project is an emitter and is supposed to be made of sheet metal. The workpiece will be deep drawn in the experimental drawing tool. An economic review by production of 1000 pieces will be worked out at the end of the bachelor thesis.

Design of bending tool for thin-waled copper tubes
Axmanová, Hana ; Peterková, Eva (referee) ; Dvořák, Milan (advisor)
AXMANOVÁ Hana: Design of bending tool for thin-walled copper tubes The project elaborated in frame of bachelor studies branch B-STG is submitting design of the bending tool for the thin-walled copper tubes. There where designed two bending tools with inner bending radius R1 = 13 mm and R2 = 45,2 mm and the bending is implemented by broach into the bending die. There were conducted some bending experiments. The tubes were bended without and with filling by a hand hydraulic press WPP15.

Drop forging of pinion
Gráf, Radomír ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
The project elaborated in a frame of Bachelor’s studies branch Manufacturing technology (2303R002) presents a technology design of a forged piece – pinion gear – made by drop forging from 14 220.0 (16MnCr5) material. Drop forging in two operations was suggested on the basis of specialized studies on the subject of drop forging and calculations. Assumed series of 120 000 pieces a year, will be produced on the drawing inclinable press LMZ 1000 A/(S) with nominal tensile force 10 MN. Swages are made of alloyed instrumental steel 19 552.8, heat-worked according to drawing documentation. At the end of the project is implemented technical economic evaluation of the technology design.

Influence of surface treatments on the quality of molded parts
Okurka, David ; Dvořák, Milan (referee) ; Hušek, Martin (advisor)
This thesis examines the influence of surface treatments on the quality of molded parts. At the beginning of this work explains why the finish and what are the current demands on the development of manufacturing technologies. It further describes the most common surface treatment of metals, which are currently very often occur. The next section is divided into forming the surface and volume and describes the different types of species-forming, such as cutting, bending, drawing, etc. At the end of the work described cooperation with the Hettich ČR, k.s. and Tokoz, a.s.
