Structural Design of Machining Centers

Yeh, Wen-Chi 14 July 2000 (has links)
The purpose of this research is to present a systematic methodology for the creative design and evaluation of machining centers. First, the graph representation is to present machining centers by using the method of topological structure. A methodology of structure synthesise is developed for the 3, 4, and 5-axis machining centers by requirements and characteristics of machining centers. A cod of machining centers is presented and configuration enumerations of the 3, 4, and 5-axis machining centers are established, and then the configuration is drew. Second, characteristics of machining centers are established to evaluate the machining centers. Finally, appropriate configuration of machining centers is selected by the cutting characteristics to compare the patents and the industrial machining centers.

Paletizace frézovací multifunkčního obráběcího centra s vodorovnou osou vřetena / PřekladačVypnout okamžitý překladPalletizing of the tilting head of a milling multi-purpose machining center with a horizontal spindle axis

Hynšt, Tomáš January 2019 (has links)
This diploma thesis deals with palletization of heavy workpieces that are used by multi-purpose machining centers. The final outcome introduces a suitable option for palletization heavy workpieces of multi-purpose machining centers. In the first part of the thesis is draft of machining centers with parameters which were chosen by exploration of market for selecting suitable solution. The second part of thesis is dealing with a detailed draft palletization made by parts of exploration of market then design palletization system and design pallet changer. The designed construction of pallet changer is dimensioned with help of analytical calculating methods and numerical simulations methods. Outcome palletization system allows automatic change of twenty tons workpieces including pallet between two storage places.

Problematika uvádění obráběcích center na trh Evropské unie a Společenství nezávislých států / The issue of placing machining centers on the market of the European Union and the Commonwealth of Independent States

Drozdov, Filipp January 2020 (has links)
This thesis discusses introducing CNC machining centers to the markets of the European Union and the Commonwealth of Independent States (currently the Eurasian Economic Union). The first chapter of the thesis focuses on the legal requirements for placing the products on the markets of the European Union and the Eurasian Economic Union, their comparison, systematic analysis of the problem, and certification schemes. The second chapter of the thesis analyses safety requirements for CNC machining centers, discusses CNC machines checklists development and their comparison for the markets of the European Union and the Eurasian Economic Union.
