Optimalizace výroby dílu pro letecký průmysl / Optimisation of a part production for aircraft industryFilipčík, Jiří January 2009 (has links)
This thesis deals with optimization of production of "Hold-down hinge hook" component, developed from difficult-to-cut titanium alloy Ti-6Al-4V. This work is focused on the material properties of the component, current research and optimization in titanium machinability sphere. Further it contains a part dedicated to the latest trends in development of cutting tools for machining of titanium alloys. This knowledge is furthermore used for the component production optimization in Frencken Brno s.r.o. company. This project continues with analysis of the component‘s current production technology and designs the way of elimination of production bottleneck. This change is presented by component‘s clamp jig, which decreases higher percentage of scrap due to the geometric complexity. This thesis further contains drawing and technological documentation needed for implementation of the improvement suggestions into the production. There was designed a new NC program. This project is accomplished with technical-economical evaluation.

Výpočtová simulace procesu třískového obrábění / Computational simulation of machiningZvěřina, Martin January 2010 (has links)
This Master’s thesis process list of different finite element programs, which allows us to simulate process of material separation. We estimated their advantages and disadvantages in the end. In program ANSYS Ls-Dyna was created 3D model, in which we simulate process of orthogonal splinter machining and we study dependence of changes different input parameters (tool geometry, depth of cut, cutting speed) on the chip form and forces rate between tool and workpiece.

Robotizované pracoviště pro opracování termoplastových dílů / Robotized workplace for treatment of thermoplastic partsSedláček, Tomáš January 2011 (has links)
The goal of this diploma thesis is to design a robotized workplace for treatment of thermoplastic products based on documentation from a real project announced by Form s. r. o. In order to understand a problematic of robots and robotized workplaces, the theoretic introduction in the beginning of work is reserved for. Besides a brief summary of robot history the introduction brings also some overview on present robot applications and it tries to classify robots into various groups according different standpoints. The main part of the theory however deals with optimized design of robotized workplaces by using a systematic approach. The topic covers also a robot safety. There are mentioned sources of safety risks and ways how to avoid them. The presented theory is at last used in the following, most crucial, part of the thesis – the final design itself. An attention is focused mainly to a design of a revolving positioner, which becomes a key element of whole workplace. Different design variants of inner most significant mechanisms are presented and by using sophisticated methods, the best solutions are chosen. Finally a simulation of whole robotized workplace is made and conclusions based on real implementation are summarized.
