Selection of an optimal tool for the selected machining technology
Podstata, Jan ; Jaroš, Aleš (referee) ; Fiala, Zdeněk (advisor)
This thesis compares the properties of four types of replaceable cutting tool inserts from different suppliers during milling. The comparative factors are cutting force, material loss of the insert and the roughness of the resulting surface. The thesis is divided into two parts - a comprehensive overview of the current state of knowledge and an experiment. The first part analyzes the load, the possibility of its measurement, surface treatment of tools, milling cutters and replaceable inserts. The experiment took the form of measuring the load during face milling, measuring the surface roughness of the machined material and measuring the material loss of the inserts on an optical strain gauge. The replaceable cutting tool inserts were compared based on the performed measurements.
Draft of pin production technology
Hrdlička, Martin ; Osička, Karel (referee) ; Jaroš, Aleš (advisor)
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.
Modification of 3D FDM delta printer frame for improvement of print quality
Butakov, Aleksandr ; Jaroš, Aleš (referee) ; Zemčík, Oskar (advisor)
This work is focused on solving the problems of delta 3d printer frame rigidity and impact of rigidity on final quality of 3d printing. A variant of a 3d printer on a classic Kossel-shaped frame has designed and built. Further, frame strength analysis and improvement design is performed, with subsequent production of a new variant and comparison of the 3d printing results of both variants. The result of this work is to show how the frame construction really affects the print quality.
Manufacturing technology of low friction rings
Svoboda, Kryštof ; Jaroš, Aleš (referee) ; Zouhar, Jan (advisor)
The content of this thesis deals with the manufacturing of the prototyped series of low friction ring, proposing of the serial production and economical and technical evaluation. This thesis also solves the surfacing of low friction rings and testing. The thesis is devided into two main parts. First part deals with selection of material, tools and process of manufacturing low friction ring. Second part concerns surfacing and after testing. The thesis ends with economic and technical evaluation.
Draft of spacer production technology
Zíka, Marek ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
The diploma thesis deals with the design of a new technological process for the production of a spacer ring with a diameter of 212 mm in cooperation with the company Meopta – Optika, s.r.o. The production of this component according to the current process does not comply with the prescribed geometric tolerances of flatness of the face and radius runout with a tolerance field size of 0.005 mm. The work is a detailed analysis of the specified component and describes the current technological process, including the machines on which the spacer ring is manufactured. Based on the knowledge gained from the analysis of the current process, a new technological process was created. During the production according to this process, some geometric tolerances were also exceeded, but the values exceeding the prescribed tolerance field were significantly reduced. The department of production technology found the results to be sufficient and the spacer ring will be produced according to the new technological process. In the last part of the work are the costs of production of components according to both processes.
Production of gearbox components
Jakubec, Thomas ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
Bachelor thesis deals with the production of a gear pair for the single speed gearbox. The projected piece production contains the making of the pinion gear; driven shaft and gear wheel. Initially the desired material and the gearbox and gears design are projected. Secondly the calculation of gearing is mathematically proven and the appropriate machining modality including measuring devices is selected. Thirdly the manufacturing procedures of each gearbox parts are optimized and the manufacturing manual is written. Finally the realization of the function unit production is documented
Design of technology production of SPD stop for bicycles
Tomek, Jiří ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
The bachelor thesis is focused on the design of shape and production technology of MTB clipless for bicycles. Autodesk Inventor software was used for modeling MTB clipless and SolidCam software was used for creating CNC program. The technology of production and description of used technologies were describe too.
Use of laser machines in small and medium companies
Šuga, Samuel ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
This thesis aims to critically evaluate the use of laser machines in the engineering industry, and with particular emphasis on small to medium-size companies focused on laser cutting. The usage of laser machines and their broad-spectrum application to various types of materials were evaluated. Using laser cutting technology, a component with optimal quality was successfully created. Thanks to this component, an experimental model was proposed, which describes how much of this product must be created for the company to stay on the market. The results suggest that using a fiber laser is the most suitable for small and medium-sized companies using laser cutting machines.
Rationalization of the clamping jaws production process for the chuck
Kovář, Matouš ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
This bachelor's thesis focuses on the rationalization of the production process of chuck clamping jaws in TOS Svitavy, a.s. The introductory part of this work presents the company and its production program. It also includes the production of manual self-centering universal chucks and clamping jaws. An analysis of the existing technology of production of clamping jaws is performed and critical points of the current production process are determined. There is also a proposition of possible rationalization solutions and then the most suitable version is selected. Than, this version is processed, a new production technology is designed and a new technological procedure for the production of clamping jaws is assembled. Finally, an evaluation of the existing and newly designed technology is performed and the conclusions of this thesis are presented.
