3D Printer Remake
Čtvrtníček, Jan ; Husák, Michal (referee) ; Arm, Jakub (advisor)
Purpose of this thesis is revitalize an existing 3D printer. It briefly summarizes the possible technologies of 3D printers with a focus on FDM technology and elaborates in more depth the possibilities of X and Y axis movement. Above all, this thesis is dedicated to the design of a 3D printer model according to selected technologies so that it meets the required parameters. Subsequent implementation is based on the precise selection of mechanical and electrical components. It also deals with the implementation of the Klipper utility software on the OctoPrint interface. The entire printer is designed as an enclosable cell with automatic print unloading.

Virtual model of manual tail test
Greplová, Kristýna ; Šindelář, Martin (referee) ; Mazůrek, Ivan (advisor)
The aim of the master´s thesis is analysis of limits of tail test exercise in practice for certification of dampening quality of wheel hitches of vehicles using virtual simulation. The goal is to create virtual model of front axle of Skoda Roomster 1.4 TDi using program Adams/View, MSC Software and follow-up simulation of tail test of wheel hitch.

Design of virtual model robotic workplace
Chromčík, Adam ; Holub, Michal (referee) ; Vetiška, Jan (advisor)
This diploma thesis deals with the design of a virtual model of a robotic workplace. Robot and robotic workplaces are researched. Further, the design and safety phases of these workplaces are discussed. A conceptual model of the robotic workplace with robot IRB 4400/60 is designed, which is placed in the machine laboratory C1 of the Institute of Production Machines, Systems and Robotics at the Faculty of Mechanical Engineering of the Brno University of Technology. The virtual model is created in Process Simulate 13.0. It is designed to manipulate the dice, weld and operate the vertical machine tool.

Evaluation of defects and disturbances of an existing structures
Uher, Adam ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
The bachelor thesis describes the most used methods of diagnostics of building structures, then it focuses on the use in diagnostics of as yet unused modern technologies, potentially replacing several activities in the work of diagnostics and other professions. The advantages of these technologies, specifically 3D scanning, are presented on a case study of the revitalization of an apartment building in Brno, Koliště 33. In the practical part of thesis is described the process of diagnosis of defects and failures of the object, including applied methods and findings. The output of the work is a proposal of measures and a set of recommendations.

Physical axle model for dynamic tests
Bělunek, Matěj ; Dočkal, Aleš (referee) ; Mazůrek, Ivan (advisor)
The aim of this thesis is the design of a physical axle test station, along with a virtual dynamic model, with the purpose of vehicle suspension tests. The axle, or half-car, model is the answer to the inaccuracies of the most widely utilized suspension model, and the high cost of the full vehicle testing. The motivation for the new test station and its virtual model is the prospect of accurate, quick and effortless testing and optimization of the vehicle suspension characteristics. The existing solutions in most cases substitute actual suspension elements (axle) and wheels with auxiliary parts leading to a departure from reality. The design of the new test station is based on the analysis of current physical model solutions and in accordance with set requirements. The tester substitutes the vehicle Škoda Fabia I Hatchback and utilizes its actual rear axle including suspension elements. The assembled rig, or rather its functionality, is successfully experimentally verified. The created virtual dynamic model, using ADAMS software, is identified against the designed test station, while the obtained simulation results are compared with the experiment data. Meeting the experiment predictions and virtual model results validates the tester’s ability to sufficiently reflect real car suspension behaviour and it is ready for further vehicle spring and damping properties testing.

Robotized machine tool operation
Lečbych, Jiří ; Štěpánek, Vojtěch (referee) ; Vetiška, Jan (advisor)
The topic of this diploma thesis is a development of a virtual interface for robot control and service of machine tools and its practical application. The actual manufacturing line is located in a company JK Nástroje s.r.o production hall. The literature research contains a summary and up-to-date state of robot programming, including means of virtual commands. The thesis describes each type of manufacturing line and its communication options between the robot and the machine. Furthermore, it characterizes individual components of the manufacturing line. The practical part deals with creating a 3D workspace model, followed by a virtual launch. This model is enhanced by drafts of additional peripheral tooling, which are involved in robotic tool changers in CNC machines, followed by practical application in a daily workflow.
