Laboratory model of an machine for printed wiring
Posekaný, Jan ; Kaczmarczyk, Václav (referee) ; Zezulka, František (advisor)
Production of printed circuit boards using three-axis CNC milling machine is suitable for small batch production. Milling machine consists of three axes, which are controlled by stepper motors. Controlled by a PC connected to the control electronics to communicate over the serial line. Input data is exported from the Eagle design software. The core of the control unit´s processor family, the AVR ATmega16, motor drivers for the ATmega8. Transfer between PC and the device is implemented using a virtual person through USB.

Tool Path Generation for 3 Axes Polygonal Models Milling
Nedvědický, Jan ; Hulík, Rostislav (referee) ; Kršek, Přemysl (advisor)
This bachelor's thesis deals with tool path generation for 3-axis milling based on 3D polygonal models. First part introduces basic terms and related topics. Main part is devoted to description of techniques and problems related to implementation of simple tool path generator. Simple milling strategies based on tool movement restricted in plane are discussed. This thesis includes implementation of plugin for OpenFlipper application where described techniques are used and practicaly verified.

Technology of product machining on CNC machines
Brázda, Jiří ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This diploma thesis deals with a technology of production milling of sample component “ending of generator shaft” by CNC milling in environment of small company. At first common aspects of CNC machines, technology of CNC milling and technology of construction are introduced. Possible problems with milling of sample component are analyzed and their possible solutions are presented. Next technology of CNC milling with operating program for CNC lathe (HAAS SL20) and CNC milling machine (HAAS VF3), production of component in small company with necessary documentation in technology procedure are projected. Using of operating systems HAAS, Fanuc and HEIDEHAIN are compared. Using of cutting tools and cutting condition for component milling is projected. Finally timing of operations and financial calculations necessary for small production of sample component is proposed.

Innovation of suspension mechanism for mountain bike
Hrubý, Patrik ; Zouhar, Jan (referee) ; Sedlák, Josef (advisor)
Bachelor´s thesis includes the description, the analyze of the issue and innovations of the bike suspension for mountain bike, including design of the geometry, shape and propose of the production in the individual production devices. Belonging work is also construction 3D model of the particular parts the bike suspension and making mechanical drawing. The next thesis hints as exploitation of the modern technologies as is reverse engineering, making models in program Autodesk Inventor or work on 5-axis CNC milling machine and their interaction.
