Inventor and PowerMILL tools for 3D machining
Přibilík, Tomáš ; Sámelová, Vendula (referee) ; Polzer, Aleš (advisor)
This bachelor thesis is focused on possibilities of usage of geometric models of work-holders created in CAD software Autodesk Inventor for more effective work with CAM software PowerMILL. Content of this thesis are basic informations about CAD/CAM technologies, creating a database of work-holders and tool-holders, demonstration of creating a work-holder, demonstration of creating a tool-holder and in conclusion a verification of possibilities of created work-holders and tool-holders in use of software PowerMILL.

Milling of Thin-Walled Parts for Aircraft Industry
Lekeš, Jonáš ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
Bachelor thesis deals with materials used in the aircraft industry, then theoretical analysis and prediction of deflection of plate and tool when machining a thin-walled piece. Then it describes an NC error compensation method, which define and minimizes a part deflection with use of three dimensional cutting force model and modeling of part and tool. Final part is about practical experiment where different computational and measuring techniques where applied to determine a part deflection.

High Speed Milling of Aluminum Alloys for Aircraft Industry
Pazdera, Lukáš ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
The aim of this paper is a complex analysis of the high speed cutting in the aircraft industry. The paper studies especially the machining of aluminum alloys, which are characterized in the first part. We can find in next chapters a view on the high speed cutting from aspect of the chip formation, the force load and the machined surface roughness. The end of the paper is focused on the issues of the CNC, machining of typical aircraft shapes and description of roughing paths, which increase the productivity.
