List of Tool Materials in Forming Operations
Horník, Tomáš ; Podaný, Kamil (referee) ; Šlais, Miroslav (advisor)
The bachelor’s thesis elaborated within the scope of full-time study of specialization B-STI Mechanical Engineering is dealing with forming technologies and choice of tool steels for the production of forming tools. In the initial part of the work we are engaged in forming theoretical background, such as forming resists and shaping rules. Another section is devoted to tool steels and their most frequent heat treatment. In the following section of search is a basic description of the selected forming operations, including the use of machines and tools and highlight of the essential elements of the technology. Requirements for material of the tool are also listed there. The goal of this work is creating steel material sheet for cutting and extrusion tools and dies. These sheets are located in the attachment of this work.

Technology project for production of part "No.2432-cover"
Bednář, Martin ; Šlais, Miroslav (referee) ; Rumíšek, Pavel (advisor)
The project developed in the framework of Bachelor's study presents a proposal of producing technology of cover "2432", part of the sheet. Based on literature research, the studies and on own experience has been produced this work. The issue of materials, cutting, piping, drawing, design of the tool, evaluation of economic and technological design production has been studied. On the basis of the combined instrument has been designed, constructed according to standards, and the use of existing machinery. To resolve it was accounted economic assessment, which enabled decision-making between the semi-finished products for production. It was found that current production is not economically advantageous, compared to the options proposed. It has been ensured and the complex layout of machines in the area of existing production.

Fineblanking component and its manufacturing
Lata, Miroslav ; Peterková, Eva (referee) ; Šlais, Miroslav (advisor)
The diploma thesis deals with a propose of a new manufacturing technology of component called „KULISA“ drawing number 4-DP-05-10/01. The beginning of this work is prepared as a literary study about blanking. There are explained some basic concepts necessary to introduce a blanking topic. Other interest of this work is an assessment of actual state of conventional blanking technology which is being currently used for component production. With regard to the deficiencies of the existing method is proposed new technology of fine blanking. In the proposal is evaluated technological site of component construction and blanking tools are proposed with stress analysis included. Last part of the work deals with the economic evaluation, where is being compared efficiency of existing and new technology.

Manufacturing of part of garage automatic door lock by compound tool
Vaverka, Ivo ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
This master’s thesis created in the master studies of the M-STG Manufacturing technology is focused on the manufacturing of a part of a garage automatic door lock by a compound tool. The part is made of a rolled steel coil of the S275JR material with the thickness of 2 mm. The number of parts manufactured per year equals to 600 000. Literary studies deals with the issues of cutting and bending. On the basis of the most advantageous manufacturing variant and technological calculations the compound tool is designed. As a working machine the eccentric press LEK 160 is chosen. In the economical evaluation part, the calculations to finding out when the manufactory becomes profitable are carried out.

Production of short shaft by extrusion
Hondl, Jiří ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
HONDL Jiří: Production of short shaft by extrusion. The project prepared as part of the Master-degree studies in the Engineering technology concerns the technology design for manufacturing a short shaft by extrusion. On the basis of the study cold forming methods and problems and following technical calculations was designed a four steps process of forming. Semifinished product has a cylinder shape with a diameter of 18mm and a length of 51,2mm. The production is designed for automatic multistage press TPZK 25 with nominal pressing force of 5 000kN from Czech producer and supplier of machinery Šmeral Brno company. Tools are made of tool steel, extrusion punch and extrusion die is designed of 19 830.4 steel, and extrusion die´s band is designed of 19 733.4 steel. Tools are designed to be improved by hardening and drawing.

The manufacturing of a flange by fineblanking technology
Povalač, Tomáš ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
Aim of the project is to design new flange manufacturing technology. The flange is manufactured from stainless sheet 17 040 with 5 mm thickness and annual production batch of 800 000 pieces. Fineblanking process has been proposed as a new production technology. Technological and construction dimensions have been designed for the proposed technology. The fineblanking process is done by automated machine which consist of unwinding and straightening device, mechanical punch press and winding device. The manufactured part is punch pressed by tool which is located in the punch press in one lift. An economic evaluation compares current manufacturing technology with the proposed technology which is more economically convenient.

The suggestion of shaped hollow cup technology
Fabík, Pavel ; Šlais, Miroslav (referee) ; Císařová, Michaela (advisor)
The project developed in the master's degree in M2-P, proposes a technology of hollow metal components DX53D+Z275N+NC with holes sheet metal forming. For batch production 225 000 units per year, on the basis of literary study problems of production of components there is designed a new way of producing components for progressive tools and it is compared with current production of simple tools. A progressive tool has 12 steps and combines them in cutting, drawing and extrusion. The tool is mounted in the hydraulic press KAISER KSTU2500 with a maximum force of 2500 kN. Simulations were performed for the campaign in the PAM-STAMP 2G 2011.
