Design of extend the machine with the possibility of separating 3D prints
Gonda, Josef ; Tůma, Jiří (referee) ; Pavlík, Jan (advisor)
Separating of the metal 3D print from the print plate is a key step in most metal 3D printing methods. The author's goal is to design a device - a clamping mechanism that expands the functionality of existing band saws for metal by the possibility of comfortable separation of prints. In the beginning of the work, the author discusses the methods of metal 3D. Furthermore, the author focuses on the analysis of the market in the given issue and a brief description of the existing solutions of world/competing band saw manufacturers. Subsequently, the choice of a specific band saw is justified and the basic properties of the mechanism are determined. An essential part is the design of solution variants and the selection of a variant based on multi-criteria analysis. Furthermore, the author analyzes the design solution of the selected variant with a description of partial details, where he emphasizes compliance with the specified conditions and product optimization.

Stress-strain analysis of clamping mechanism element
Gergeľ, Erik ; Navrátil, Petr (referee) ; Skalka, Petr (advisor)
The bachelor thesis deals with creation of computational model and solves Stressstrain analysis of a car window clamping mechanism element. The main focus of thesis is to locate a critical area of part and find out the distribution of stress is this area. FEA system ANSYS was used for this analysis. The shape optimization based on results of FEA was successful. The equivalent stress was significantly lowered. It would be able to increase the operating time of clamping element.

Construction of a brake mechanism
Laštůvka, Martin ; Galas, Radovan (referee) ; Frýza, Josef (advisor)
The bachelor's thesis describes design of brake and arrestment mechanism for high pressure viscometer which is placed in the laboratory of the Institute of Machine and Industrial Design FME BUT. The Brake mechanism is able to brake torque of 50 Nm and the arrestment mechanism allows to stop the shaft at precisely defined angles. When designing the device is used current the state of knowledge.

Design horizontal exchange of the head - VA1-C
Vyplašil, Jan ; Holub, Michal (referee) ; Sýkora, Jan (advisor)
Diploma thesis deals with the concept of interchangeable straight spindle head type VA1-C, used for automatic clamping in 80 kW spindle head from production of TOS Kuřim. Thesis contains survey of interchangeable heads, analysis of the spindle housing, strenght analysis of the spindle with the safety calculations in critical sec-tions and analysis of the clamping mechanism together with the calculation of the camping force, which holds the tools in the spindle. Analysis of the camping mechanisms contains calculation of the contact stress between balls and housings. All results are shown in the graphs. In the last part of the thesis are described the construction elements using the model of the interchangeable head. Enclosed is the assembly drawing of the spindle head, bill of material, detail drawing of the spindle and also 3D model of the interchangeable spindle head.
