A technological preparation of the wiping plate production
Balhar, David ; Dvořáková, Jana (referee) ; Píška, Miroslav (advisor)
The main aim of this master's thesis is to propose a technological preparation of the wiping plate production. Elaboration is divided into four chapters. The first chapter describes forming tool (function and construction). In the second chapter is technologies overview, which are used for the wiping plate production. The most important is the third chapter, because it deals with the main output, and the actual proposal of technological preparation of the production. In the fourth chapter, production is reviewed economically.

Production single parts "COVER" from sheet metal
Vítek, Roman ; Císařová, Michaela (referee) ; Žák, Ladislav (advisor)
The Master’s thesis written in the frame of studies branch Manufacturing Technology (2303T002) is submitting design of technology production of sheet metal cover. The part is made of sheet metal 1,5 mm thick. The material for the part is HC260LA (ZStE260). There are no special mechanical or dimensional accuracy demands for the part. According to production run (5 000 pcs. per year for 5 years), design complexity and machine accessories of submitter was proposed manufacturing the part by drawing technology with finish laser cutting. Forming tool is designed according with press Erfurt PKZZ 315. Thesis includes economical evaluation of elaborated technology with other variants of production.

Technological design of the single-part production of former
Svoboda, Lukáš ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
This dissertation in the engineering study of the Engineering technology deals with the proposal of the unit production technology of two pieces of the tool for cold forming of the material X 45 NiCrMo 4, standard W. Nr material number 1. 2767. The production is on the demand and is therefore trial, because the specified tool has not been till now fabricated. The thesis describes an analysis of manufactured components, as well as a description of the material used, a description of the available technologies that were used and a design of production technology. The production will include these methods: turning, grinding, electro erosive deepening and polishing.

Design of forming tool production technology using the additive method of 3D printing
Obadal, Jan ; Vašíř, Jakub (referee) ; Sedlák, Josef (advisor)
This bachelor thesis deals with a plan of a forming device manufacturing technology utilising additive methods of 3D printing. The theoretical part of this thesis deals with the characteristics of sheet metal forming technology and the characteristics of additive technology. The practical part of this thesis contains a breakdown of the current state and it deals with usage of the current forming tool. In terms of the practical part, there is an innovation draft whose goals it to speed up the manufacture of a particular pressed piece. The principle of this innovation is the utilisation of a single-purpose machine which is optained through the additive method of 3D printing. The optimal combination of printing parameters and tool geometry are found through prototype testing. To keep the product measurements accurate requires modified proportiong of the semi-finished product. The final tool is capable of bending two pressed pieces at the same time. During the process of bending, it is necessary to review the measurements of every 25th pressed piece and to revise the position of a bottom dead center. The lifetime of this innovative tool is set to 600 pieces. Technological and economical evaluation shows return of invesments and reduced time due to the application of this innovation, thanks to which the bending time is reduced by 50 %.

Production Possibilities of Punching Machines
Dolejš, Radim ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
This thesis introduces the elementary principles of punching, stemming from the gradual shearing theory. Furthermore, it includes description of instruments used in cassette and revolver systems. Forming tools are then also defined. The thesis details the parameters of individual parts of the punching machine, and an example of a hybrid laser-punching machine is then presented.
