Výroba prototypu automobilu s využitím moderních metod a technologie CAD/CAM / A car prototype manufacture using modern methods and CAD/CAMHorák, Aleš January 2010 (has links)
The project developed under the engineering studies, solves the problem of production of a prototype car using modern technology, reverse engineering and CAD / CAM. Based on the literary study of the issue, was designed process of digitization of the physical model of car, including the treatment and processing of data. Follow-up step was to verify the production of the additive rapid prototyping technology - FDM method. Verification of the results was performed on a vertical milling cantilever FV 25 CNC with control system Heidenhain iTNC 530 using a cutting strategies by PowerMILL CAM software. At the end of the resulting models edit as necessary.

Nové frézovací nástroje z rychlořezné ocelí pro hrubovací operace / New Milling HSS Cutters for Roughing OperationsJaroš, Aleš January 2015 (has links)
Dissertation thesis is focused on development, design and production of the new milling cutter which is used for roughing operations. High-speed steels, coating technology and milling technology are described in first chapters of dissertation thesis. The main part of this thesis is the design of the new milling cutter that has been designed on the basis of the machining simulation. The milling cutter is designed as a three-flute cylindrical end mill made of high speed steel. The each flute is composed of two special compensation edges. The compensation edges are used for reducing (at best suppression) tensile stress in the heel of the tooth. The milling cutter was made by lost wax technology, followed by grinding and thermal treatment. New designed tools were deposited by PVD coatings (e.g. (Al,Ti)N). Standard catalog milling cutters (producer ZPS - milling tools, Zlín, Czech Republic) were used for comparison the designed milling cutter. Carbon steel CSN 41 2050 (DIN 1.1191) was used for milling, which was carried out with using process liquid. The monitored parameters were force loading, flank wear and tensile stress during milling. The dynamometer Kistler was used for measuring force loading and data obtained during machining was used for stress analysis.

VYUŽITÍ 3D TECHNOLOGIÍ VE VEŘEJNÉM PROSTORU / THE USE OF 3D TECHNOLOGY IN THE PUBLIC SPACEŠebánek, Jan Unknown Date (has links)
The aim of this thesis is to define the impact of rapid prototyping technology in terms of creative potential to use this technology represents a particularly sculpture and architecture. Rapid Prototyping is a generic term covering a range of technologies: 3D scan converting the already realistic three-dimensional objects in computer memory, parametric modeling, which creates three-dimensional objects based on the formative algorithms, photogrammetry method of compiling three-dimensional object from a photo, technology, 3D printing materializing after each layer objects transferred from the computer's memory. When processing the theoretical work will be explored and discussed possibilities for realization of basic three-dimensional objects using 3D technology. The second step will be to map the different methods of access to artists working with 3D technology. In the end it tried to evaluate the benefits of these technologies in the field of sculpture and architecture in terms of traditional approaches. This paper attempts to describe the possible implications and potential of this progressive field in the classical artistic disciplines such as sculpture and architecture, both in terms of benefits and in terms of the eventual negative impact with respect to increasing the availability of this technology.

Der Weg zum digitalen Zwilling mit Mainstream CAD-LösungenSchawohl, Elke 05 July 2018 (has links)
Von der ersten Idee bis zur Auslieferung eines Produktes laufen verschiedene Prozesse ab, die koordiniert und optimiert werden, um Produkte schnell zur Marktreife zu entwickeln. Die Digitalisierung von Prozessen sowie eine firmenweit einheitliche Datenplattform sind in der Produktentwicklung zwingend notwendig. Digitaler Zwilling, und PLM rücken in den Fokus. Die Herausforderung der Industrie liegt in der Optimierung von Produkten. Wo beginnt die Optimierung? Während der Konstruktion greifen verschiedene Optimierungstools in die Entwicklungsphase ein. Skalierbare FEM-Tools ermöglichen konstruktionsbegleitende Analysen. Verschiedene Konstruktions-Tools in der CAD-Lösung sparen Zeit und Kosten. Die Konstruktion der nächsten Generation Generative Konstruktion – bei der Modellerzeugung werden die Vorteile der additiven Fertigung einbezogen und somit die Bauteilkonstruktion optimiert. Reverse Engineering bietet die Möglichkeit direkt mit Facettendaten zu arbeiten und Flächen zu generieren. Convergent Modeling bietet die nahtlose Kombination von „B-Rep“-Volumen und „Facetten“-Modellen. Solid Edge Portfolio - die Zukunft der Produktentwicklung Solid Edge Apps erweitern den Funktionsumfang. Auf bestimmte Marktsegmente entwickelte Applikationen runden die Anwendungsmöglichkeiten ab.

Neue Freiheiten bei der Konstruktion durch den Einsatz von Topologieoptimierung und additiver FertigungWaidmann, Axel 22 June 2018 (has links)
Durch die neue Schweißfunktionalität in Creo 4, welche es ermöglicht Schweißnähte als Volumengeometrie zu modellieren, entstehen viele neue Möglichkeiten zur Berechnung der Spannungen innerhalb der Schweißnähte. Damit einhergehend entstehen neue Möglichkeiten zur Berechnung und Evaluierung dieser Schweißnähte nach den Richtlinien der FKM. Die Berechnung anhand der FKM-Richtlinien soll hierbei anhand der zwei Simulationstools Creo Simulate und Ansys Simulation dargestellt werden.
