Simulation and optimization of a manufacturing process in the application of injection molds in forming departments
Nagy, Martin ; Zouhar, Jan (referee) ; Píška, Miroslav (advisor)
This bachelor thesis is focused on the simulation and optimization of the manufacturing process in the application of injection molds in forming departments. The theoretical part describes the process, model, approaches to the process of modeling and software support of the simulation. The author introduced the basic elements of software FlexSim, whose knowledge was crucial to create a model in the practical part. In this part the author describes the formation and function of the model and then he experimented with this model to find optimal solutions for the specified problems. Experiments concluded that the weak point of the process is low utilization of some machines and employees. For these weak points of the process, the author suggested specific solutions.

Silicone molds and their use
Rudolf, Jiří ; Zouhar, Jan (referee) ; Jaroš, Aleš (advisor)
Bachelor thesis is focused on the design and production of a headphone holder. Thesis is divided into theorethical and practical part. The theoretical part is described Rapid Prototyping technology, precision casting with use of silicone molds and precision investment casting. The practical part is focused on the design of a headphone holder in CAD system Autodesk Inventor and following production via two different methods. The first way is 3D printing by Fused Deposition Modeling method and the second way is casting wax and plastic models using a silicone rubber mold. Conclusion of this thesis contains technical-economic evaluation and comparison of both manufacturing methods.

Method for evaluation accuracy of milling robots
Cabalka, Jan ; Slaný, Martin (referee) ; Zouhar, Jan (advisor)
This thesis describes the design of methodology for measuring the accuracy of robot machining. It describes the theoretical properties and classification of commercially available methods for precision measurement. In the practical part, a test workpiece is manufactured and positions and toolpaths are measured by the Pontos system. The proposals are based on the MCAE Systems company's equipment.

Assembling and Functional Verification of a Home 3D Printer
Tesař, Jaroslav ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
This thesis was created as a bachelor project in the Faculty of Mechanical Engineering at VUT in Brno. In the theoretical part, the additive technology Rapid Prototyping is introduced together with the most common methods, followed by the assessment of advantages and disadvantages of the new technology and its possible uses in various fields of human activity. In the experimental part of the diploma thesis was assembled and the printing parameters were set. Consequently the comparison models were printed on the 3D home printer and on professional printer Dimension uPrint. The accuracy of the printers is compared. The thesis concludes with the analysis of technical and economical parameters.

Robotic machining of composite materials
Rubišar, Václav ; Sedlák, Josef (referee) ; Zouhar, Jan (advisor)
This thesis deals with the robotic machining of composite materials. It is divided into two main parts - theoretical and practical part. The theoretical part is focused on detailed introduction of the term “an industrial robot” and a description of its controls, types of the robots, types of their propulsion and programming methods. Furthermore, there is a list of CAM softwares with its specification designed for both conventional machining and machining by using a robot. It also includes the introduction of composite materials and specification of their machining. The practical part deals with selection of appropriate type of bracket spindle by using a simulation software, suction design and economic evaluation of two types of machining in manufacture.

Simulation of rolling operation using explicit FEM
Bezrouková, Martina ; Zemčík, Oskar (referee) ; Zouhar, Jan (advisor)
The purpose of this work is to introduce explicit finite element method (FEM) and to familiarize with commercial software tools witch are capable to perform simulations. The technological conditions and the scope of application of roller burnishing are described in subsequent part. The simulation model of roller burnishing was created. Software ANSYS LS-DYNA was used to make computations. The results of simulation and technical and economical benefits of roller burnishing are presented in the conclusion.
