Analýza nábytkových CNC obráběcích center v návaznosti na vlastní návrh a výrobu prototypu nábytku uzpůsobeného pro výrobu na CNC

Novotný, Lukáš January 2015 (has links)
The diploma thesis at first deals with the analysis of furniture CNC machining centers, which leads to the selection of the most suitable machine for a specific company. Second part of the thesis is to design furniture that is adapted for production on the furniture CNC machining center. Coffee table is chosen for design and manufacturing. The thesis contains both a theoretical study of the problems of CNC manufactured table furniture and practical part which describes the process of selection a suitable machine for a specific company and also describes whole process of creating a new furniture. The creation itself is described from sketches through material selection, appropriate joints to the prototype manufacturing. Coffee table which is designed and manufactured contains component, which is used in the design of dining and work table.

Návrh univerzálního dělicího nábytkového prvku

Culková, Hana January 2015 (has links)
This diploma thesis deals with design and construction of the room divider intended for CNC manufacturing. Another aim is to create a functional magnetic joint between the panels of the screen. Thesis is divided into two parts. The first part is theoretical. It describes the use of room dividers in history, and their types and nowadays uses. It also deals with the topic of CNC technology, use of the technology for the furniture manufacturing, suitable materials and joints. The second part is focused on the development of design and constructional solutions of the room divider.It presents its variants, safety requirements, magnetic joint and stability calculation of the screen.

Návrh dřevěné stavebnice / Design of wooden building kit

Vinopalová, Pavla January 2016 (has links)
This thesis describes the design of wooden building kit on the principle of gears. Summarizes the problems of calculations and graphic design for gears, work with computer software, and then the laser and the CNC device. Presents the pros and cons of making such building kits in both machining methods and draws conclusions about their suitability and economy. Provides overall production process, from market research (which similar building kits are usually trade in Czech republic nowadays), the numerical and graphic design, to verifying the functionality of the prototype. The thesis is based on scientific literature that addresses the issue of gears, tooling, surface finish of wood etc. It must also take into account the Czech legislation and standards concerning toys.

Návrh nábytkového prvku bez kovových a lepených spojů

Dias, Jiří January 2016 (has links)
The aim of this work was to design a furniture element without metal and glued joints. The thesis is divided into theoretical and practical part. In the first part is the characterization of materials and their processing methods, where the work is dedicated to the conventional method CNC and mostly unconventional technology of 3D printing. The research of constructional solutions of furniture was created afterwards. No glue, nor any metal components was used. The final phase of this work is to design own original constructional solution, which is applied to the storage furniture element - shelving system.

Návrh a realizace vrtačky na plošné spoje / Design and implementation of a PCB drill

Stuchlý, Martin January 2021 (has links)
This thesis is focused on proposing a design and providing the realisation of a CNC drill used for printed circuits. The first section is concerned with researching the background of CNC drills, which is followed by the proposed design and realisation of a custom model. Fundamental calculations and individual constructional aspects were carried out based on the chosen parameters. Furthermore, the operating electronic functions and the description of a G-code generating program is the main content of the second section. Finally, the last part of this thesis includes economic evaluation and the CNC drill’s assessment in practice.

Multifunkční zařízení na výrobu ozubení / Multifunction gear cutting machine

Danda, Libor January 2017 (has links)
Diploma thesis deals with the design of a small, computer-controlled machine tool. It is used for gearwheels production and combines the two most used manufacturing methods. The dissertation was dealt with in cooperation with a business subject which focuses on the development of milling machines. The introductory section is discussing research of current state of knowledge and market research focused on gearing machine tools, including patent investigation. The conceptual solution is discussing several variants of the cinematographic arrangement of the axes from which the final design solution was developed. This is described in detail in the second part of the dissertation. It contains description of individual construction complexes, choice of propellant units, modal analysis of sliding systems using the method of finite elements and in the conclusion the electronic part of the machine with its overall shape solution.

Návrh technologie výroby čepu / Draft of pin production technology

Hrdlička, Martin January 2020 (has links)
The Master's thesis, written during the study of M-STM Manufacturing Technology and Management in Industry, is focused on the concept of the production technology of a pin. The thesis includes a description of forming and machining technology in terms of possibilities of their application in the production of the pin. Furthermore, by comparing both technologies and preliminary economic evaluations of production, it leads to the choice of the production method. This production method is then described, and the description contains the production process steps including the creation of the CNC program. The conclusion of the thesis is devoted to the technical and economic evaluation of the production concept.
