Design of a milling fixture for four-axis CNC trimming of composite parts
Hibš, Dominik ; Slaný, Martin (referee) ; Zouhar, Jan (advisor)
This thesis deals with the design of a milling fixture for trimming of folding propellers for the company Mejzlik Propellers s.r.o. Firstly, an adequate HAAS DM-2 machine and UniCut Dron milling tool were selected. The cutting force was then quantified at 9.2 N. Once the cutting force was established, the clamping surface could be designed and the clamping force set at 317.3 N. After considering several fixture options, the final design was selected. The selected design was used to program the CNC machine in Fusion 360. A technical and economic evaluation followed, when the total price of the product was 41,671 CZK and the cost of machine cutting one propeller was 32.60 CZK, while the cost of manual trimming was 29.10 CZK
Design of a device for profiles painting on a pultrusion line
Krejčí, Miloš ; Slaný, Martin (referee) ; Zouhar, Jan (advisor)
Surface treatments of composite materials represent a specific issue in terms of the design of automatic painting equipment. The surface treatment modules were designed to be integrated into an existing pultrusion line, with an emphasis on maintaining the ergonomics of the workplace and adhering to space requirements. The selection of a suitable paint was first made from the coatings available on the market, then continued through collaboration with the manufacturer. The collaboration led to the development of a powdered, thermally curable formulation and a liquid, UV curable formulation. After adhesion tests, an optimised version of the UV formulation was selected. The design of the coating equipment is based on the requirements specific to the selected UV curable formulation. It consists of technologies for UV surface pretreatment, paint application and UV curing of the coating. The surface pretreatment is based on the experience of the supplier of the application technologies and own experiments. Coating application uses spray guns, again selected on the basis of testing in production. Curing of the coating is provided by a set of UV emitters with adjustable output power. Cost savings due to automation of the process and elimination of human labour are insignificant under current conditions due to the high price of the selected coating material. If the predicted production volumes are achieved, the savings can reach up to 10-12 CZK per linear metre of profile.
Design of an LED laser module with a power of up to 6 W
Chovanec, Daniel ; Slaný, Martin (referee) ; Dvořák, Jaromír (advisor)
The work is dedicated to laser modules for engraving and cutting materials. The theoretical part describes the basic principle of laser technology. It is more closely focused on the func-tion of laser diodes, basic types and possible modes of operation. Futhermore, control electronics are mentioned, their power supply and controls. In the practical part, a module designed for manual engraving was constructed. The design was conceived with an emphasis on small dimensions and low weight. The achieved parameters were tested by the module attachement to machinery that has continous movement. Tests confirmed sufficient laser power for engraving and cutting low-density material. In the final part, the construction of a new module was proposed, enabling installation on an engraving machine. Subsequently, a mechanism was added to enable precise adjustment of the focal length of the beam depen-ding on the thickness of the material.

Design of Technology and a Constructional Solution of a Device for Cutting of Magnetic Points with the Use of CAD/CAM Technologies
Kolomý, Adam ; Fiala, Zdeněk (referee) ; Slaný, Martin (advisor)
The focus of this bachelor's thesis is the evaluation of the current state and the design of a new device for fitting magnetic points. In the theoretical part of the final thesis, expert knowledge of this issue was needed. Based on the synthesis of theoretical knowledge, evaluation, and assessment of problematic parts of contemporary equipment, a piece of new equipment was designed that works more efficiently and effectively. At the end of this work, both devices will be compared in terms of their performance and production cycle. The outcome of the investigation will be time-saving when using the newly constructed device.
Machining of thin-walled components on a CNC lathe
Veselský, Radim ; Kolomý, Štěpán (referee) ; Slaný, Martin (advisor)
This work was focused on the design and production of a clamping device for clamping thin-walled circular workpieces on a CNC machine. Cutting forces were measured using a dynamometer. From these forces the highest power was derived. The minimum clamping force for clamping the workpiece was calculated. Using simulation, the most suitable angle of spacing of the clamping surfaces was determined. Based on this finding, the jaws were designed and manufactured. 5 samples were processed. Three samples were machined in the original jaws, two samples were machined in newly manufactured jaws. Each jaw was clamped with two specified clamping pressures. The machined samples were scanned with an optical scanner and measured in a measuring program. A clamping simulation took place with the determined pressures of both jaws in the simulation program. Conclusions were drawn from the calculations and the verification experiment.

Šrenk, Vojtěch ; Dvořák, Jaromír (referee) ; Slaný, Martin (advisor)
The thesis deals with the design and implementation of a rotary axis in a CO2 laser cutter for the ability to cut and engrave rotary workpieces. The thesis is focused on identifying several similar available known competitive solutions, for which the pros and cons were evaluated. Based on the findings, suitable parameters were selected to achieve maximum versatility of the proposed system. Versatility in this respect is related to the ability to cut and engrave the widest possible range of rotary workpieces. The thesis also describes the design solution, axis assembly procedure, production design and production of individual components using 3D printing technology (FFF), selection of suitable standardized components and the actual implementation. The conclusions then focus on the proposed solution from an economic and technical point of view.
