Šrenk, Jakub ; Dvořák, Jaromír (referee) ; Slaný, Martin (advisor)
This work is focused on the problematics of small CO2 lasers and their possible use for commercial production. The first part describes devices available on the market and evaluation of their parameters. The practical part specifies the parameters that arise from the potential use of technology. Based on these parameters, design of the machine and its complete mechanical design are elaborated. Furthermore, the experimental part deals with the design of structural components, control system, electrical systems and in general a complex technical-technological solution of the equipment, including economic evaluation of the design. Part of the work is also the construction of the machine itself, including activation, adjustment and debugging for the considered production. The constructed machine was subject to testing to ensure required quality of production.

Manufacturing of the support arm
Melichar, Ivo ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The thesis introduces a design for the technology of manufacturing the supporting arm used for positioning and rigidity of the front plate in relation to the metal socket in the container box. The arm is made of a 2 mm thick steel sheet and of a quality according to ČSN 411331 in a production series of 14,700 units / year of the left modification and 14,700 pieces / year of the right modification. After the assessment of individual production options, the cutting technology in a progressing tool and bending technology in a simple tool were selected. Based on a literary study on cutting and bending, an optimal process of arm manufacturing was proposed. After the design, technological and control calculations for individual technologies, the tools were designed, and the technical documentation for those tools was developed. For the cutting technology, an Andritz Kaiser press with a PV120F / 1 labelling was selected. For the second production step, bending technology, a press from Šmeral Brno a.s. with a LEN 63 labelling was selected. Both of these presses meet the requirements of both the forming force and the tool dimensions. After the economy of production was assessed, production costs of one piece were determined with a 30 % profit assumed to 28.47 CZK. The turning point when production became profitable was found after the production of 18,121 units.

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.

Use of modern technologies in the production of flat sheet metal parts
Kohoutová, Zuzana ; Podaný, Kamil (referee) ; Špaček, Jindřich (advisor)
The final work elaborated in the scope of master's studies of the branch 2303T002 submitted use of modern technologies in the production of flat sheet metal parts from the material 11 373. Work is set for cold shaping of metal by means of cutting. Production on sequence shearing tool is based on series 350 000 pieces per year. Universal hydraulic press CUPS 63 DEU with shearing force 630 kN is selected for realization. Work is also focused on the production of the same components using plasma, laser and water CNC equipment and the subsequent economic evaluation of all variants of the production. In enclosure there is drawing documentation for cutting tool.

The manufacturing of feed sheet metal component
Pašalov, Tomáš ; Matušková, Jarmila (referee) ; Peterková, Eva (advisor)
The project made within the bachelor‘s program B2307 represents a proposal of the production technology of a cutting – a device made of steel plate 12020. On the basis of secondary literature dealing with the problematic topic of cutting technology a production of components in sequential device was designed. The sequential device is composed of normalized components and is resolved by using a universal easel. The cutting box is fixed to the compressing machine LEN 40 C (producer TOMA Industries, s.r.o.) with the nominal drawing force of 400 kN. The upper cutting edge and cutting form are made of tool steel class 19, heat-treated according to the drawing documentation.

Proposal for the production of variants of flat sheet metal parts with holes
Fabík, Pavel ; Hušek, Martin (referee) ; Špaček, Jindřich (advisor)
FABÍK Pavel: Proposal for the production of variants of flat sheet metal parts with holes The project elaborated in frame of bachelor’s study branch B2307-00 submits a design of technology components from sheet metal with holes - parts of steel 11 320.1 (specified by INGE Opava). On the basis of literary study problems of production of the components were designed and compared two methods of production. Cutting on the combined cutter attached to the double-stand hydraulic press type Tleff (designed by KIT Invest Ltd. for the Trading) witch 4000 kN pressing power. The cut parts of cutting tool are made of material 19 312 (as designed by Brano). Laser cutting is done on a machine AMADO FO-3015 (in the company Dender).

Manufacturing of clasp
Polách, Libor ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The project is focused on proposal of clasp technology production. The clasp is a part of central lock in parachute harness. The part is made of galvanized steel sheet metal, sheet metal thickness 3 mm. The part has a spatial shape with holes. Expected manufacture series is 25 000 per year. Bassed on literary studies and manufacture requirements on the clasp, the method of cutting combinated with stamping in combined tool was found the most optimal. The final shape of clasp will be done in three steps. The nobel steel 12 050, which performs required mechanical properties, was chosen as the main material for clasp manufacture. The manufacture will be made by eccentric press LEXN 100C. The expected price of the clasp is 9,7 CZK per piece with counting the procurement price of metallurgical semi-finished product and the tool.

Laser micromachining
Láznička, Pavel ; Daněk, Ladislav (referee) ; Mrňa, Libor (advisor)
This thesis deals with lasers, their general theory and application. Then a theoretical part describes laser micromachining and engraving. Experimental part of thesis deals with several experiments performed by powered fibre laser which is not primarily intended for the field of micromachining. Experiments were mainly evaluated by several types of microscopes where the amount of removed material was appraised. By particular experiments removed material was in accordance with used working parameters of laser and a significant role plays machining material. It emerges from the experiments that for the field of laser micromachining and engraving shorter pulses are more suitable (minimal pulse duration was 1 ms in experiment) and it is connected even with a way of removing material. Applied powered laser can be used for micromachining in specific fields of production.
