On the production technology of a specific part
Kalina, Adam ; Slaný, Martin (referee) ; Píška, Miroslav (advisor)
This document describes the design of new production technology specific part in an engineering company. The specific part is manufactured on a machining center by milling method. To create model was used SolidWorks software and to create CNC program was used SolidCAM program. There is production process created with new and old technologies. There is a comparison of both technologies in conclusion.

Design of NC hydromechanical vise
Václavek, Marek ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This thesis focuses on design of a machine vise with a hydromechanical clamping force multiplier. The thesis is split into three main sections: study of workholding methods and fixtures with emphasis on vises, introduction and explanation of the proposed design and necessary calculations for the proposed design.

Rationalization of segment production of the forming tool
Pilař, Radek ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
Master thesis is focused on the rationalization of production of the forming segment, which is manufactured by company OMNI-X CZ. Familiarization with the product „forming segment“, with issue of production with possibility improvment. The work is also focused on the preparation of the clamping fixture, which should improve the production conditions. The main point of the work include the calculation of cutting forces, clamping forces of the fixture, verification of safety process with economic evaluation. The aim of this master thesis is to indicate the possible direction of the rationalization of the manufacturing of the shaping segments for OMNI-X CZ.

Measuring the flexibility of vehicle suspension components
Gadas, Petr ; Zháňal, Lubor (referee) ; Míša, Jiří (advisor)
This bachelor’s thesis describes suspension kinematics and elastokinematics of vehicle axles, contains the design and manufacturing method of a jig, designed to measure kinematic complience of each suspension assembly, and deals with the measuring process and data evaluation. The goal is to measure the stiffness behaviour of suspension components of a Formula Student car Dragon X and to assign it to a multi-body software suspension model, which will result in a more detailed vehicle model, to achieve simulations that are closer to reality.

Design of apparatus for determination of directions of reinforcing fibres in soft biological tissues in their deformed state
Sodomka, Tomáš ; Vaverka, Jiří (referee) ; Burša, Jiří (advisor)
The Bachelor´s thesis is focused on the determination of directions of collagen fibres in elastic arteries. The first aim of this thesis is a general introduction into soft tissue mechanics with turning attention to connective tissue where collagen fibres are their inseparable part. Also the thesis introduces arrangement of collagen fibres, their waviness and how the waviness thwarts determination of direction of fibres. The second aim is a design and test of the mechanical apparatus, which is able to stretch a squared aortic sample in two perpendicular directions (independently on each other) up to the relative deformation of 30 %. Design of the apparatus allows the sample to be dipped into the formaldehyde solution, which fixes the deformation. Consequent histologic sections of the sample will be used for the determination of global directions of collagen fibres in the aorta. The apparatus is designed to simulate conditions in a human or animal body where aorta is axially pre-stretched and at the same time expanded in the radial direction by blood pressure.

Production of a Jig Using Rapid Prototyping Technology
Růžička, Jan ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
The subject of this thesis is the design, modeling and manufacturing of complex shaped parts using modern additive technology Rapid Prototyping. The theoretical basis of the work is involved in Rapid Prototyping and CAD systems and their technology, terminology and basic terms. The analytical part is dedicated to the implementation of the design – construction of the model in parametrical software SolidWorks followed with a creation of the part using 3D printer uPrint working on Fused Deposition Modeling method. Conclusion of this work compares this method with CNC machining and evaluates which method is more efficient and more economical.

Design of stand for torque measurement
Zerzánek, Ondřej ; Zeizinger, Lukáš (referee) ; Čípek, Pavel (advisor)
This bachelor thesis deals with design of stand for torque measurements and additional fixtures. Issue is realized by aluminium profile systems and manufactured or purchased parts. Solution takes in account limited manufacturing options. Final part of this thesis is 3D model and critical evaluation of design. This thesis is useful example of how to create torque stand instead purchasing expensive commercially available stand.
