Robotic machining with external tool
Ryvol, David ; Pochylý, Aleš (referee) ; Kubela, Tomáš (advisor)
The goal of this final thesis is to evaluate the performance of chosen CAM software in robotic deburring of cast parts while using external tool. For this purpose, an analysis of program’s functions was carried out and toolpath-making strategies were compared. The most appropriate strategy for mentioned technology was chosen based on this analysis. The generation of a toolpath was described on the example of real part from automotive industry. In order to simulate real machining process, a model of workspace was created, proper tool with spindle was selected and a method of clamping the workpiece was designed. A postprocessor was created, and so was the robot program, after successful simulation, as a foundation for possible practical test. PowerMill software proved to be not very suitable for this kind of machining application, mainly because of high amount of time consumed during the whole process. So the original idea of replacing classical on-line programming with this software is not advised.

Machining of the Formula hub on CNC Machining Centre
Jelínek, Petr ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
The master thesis deals with design and manufacturing of rear right formula hub on CNC machining centre by using modern CAD/CAM technologies. The theoretical part is focused on description and characterization of milling technology and machinability of aluminium alloys. The practical part is focused on the designing formula hub in CAD software Pro/Engineer, proposing machining strategies by using CAM software PowerMILL and manufacturing on CNC machine. There is technical economic evaluation of the machined part at the end of the thesis.

Designing and Producing a Differential Holder and Eccentric for a Formula Student Racing Car Using Workshop Oriented Programming and Modern CAD/CAM Technologies
Vejtasa, Vladimír ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
The present master thesis deals with the application of workshop programming and advanced CAD / CAM technology to the design and production of differential holder and eccentric of Formula Student car. The first part characterizes and describes the technology of milling, drilling and boring. There is also a selection of material to be machined, including the characteristics of aluminium and its alloys. The following section describes the construction of differential holder and eccentric in the parametric program Autodesk Inventor and creation of CNC programs using the workshop programming and CAM of PowerMILL system. The conclusion section refers to the production of both components in the training centre BOSCH DIESEL s.r.o in Jihlava. The thesis is concluded with a technical-economic evaluation and analysis of both proposed production variants.

Production Concept of Vacuum Mold for Plastic Forming
Tišnovský, Jakub ; Kalivoda, Milan (referee) ; Sedlák, Josef (advisor)
Vacuum plastic forming is method of termoplastic material treatment. This method uses physical and mechanical changes caused in materiál during his heating. Production of final product requires mould. The main advantage of this technology is fact, that manufacturing of mould is not so hard as manufacturing of mould for injection moulding, so mould is signficantly cheaper. Main purpose of this thesis is to propose production concept of this mould. Proposal was solved by SolidWorks and PowerMill software and manufacturing was realized on 3-axis CNC milling machine. Main result of this thesis is a summary of instructions which can be used in proposes of different moulds for vacuum plastic forming.

Comparison of roughing strategies in various CAM softwares
Hrabovský, Adam ; Sedlák, Josef (referee) ; Zouhar, Jan (advisor)
Bachelor’s thesis deals with roughing strategies especially with those included in chosen CAM software. The initial part states the common information about the effects on precision of machining and tool load. Next chapter deals with methods of machining and their resulting requirements on construction of the machine. It is followed by the description of new roughing strategies and their utilization; also roughing tools were selected for machining of specified models of mold parts, made of steel and aluminium alloy. In the practical part, roughing strategies were applied to stocks which were subsequently compared by the machining times.
