The tribological behaviour of process fluids using different friction pairs
Bakalova, Totka; Voleský, Lukáš; Louda, Petr
2015 - English
Tribology includes the processes of interaction at the interface between solid, fluid and gaseous bodies. The task of tribology is to ensure that relative movement of the two surfaces was carried out with the minimum loss of energy and materials. These factors define the tribological properties of the newly created functional surface with the use of lubricants. Tribological properties mainly describes the coefficient of friction and wear, which depends on the type of friction and mechanism of wear.
During the examination of the effects and impacts of friction we look at the system consisting of two bodies, their contact surfaces and a material that is between them and close surroundings, such as the tribological system. Friction has a significant influence on the technological properties of process fluids and can lead to a reduction of lifetime and it can also change the functional properties. Lifetime of lubricating and cooling process fluids is one of the fundamental aspects that determine the quality of the fluid and its also affects the process and economic expensiveness.

Micromachining with usage of LASER
Čermák, Adam; Stankevič, Valdemar; Kožmín, Pavel; Šrachta, Petr
2015 - English
This article combines basic information of laser problems and options of laser process controlling during microm-achining. Possibilities of process controlling from view of laser source are characterized. The interaction of laser beam with workpiece (absorption and laser pulse length) is briefly defined. Next chapters deal with laser setting, which is divided into movement controlling of laser beam and laser beam setting from view of process parameters. Other part of the article compares advantages and disadvantages of micromilling and laser micromachining, where the similar attributes are confronted. The end of this article is dedicated to summarization of problems, which occur during laser micromachining, conclusion and possible recommendations eliminating mentioned prob-lems.

Automatic measuring workplace
Kubátová, Dana
2015 - English
Surface integrity is gaining unprecedented importance and some areas of metrology are also very intensively de-veloping along with it. Controlling also plays a big part in conjunction with 3D measurement. This article de-scribes the possibilities of combining the requirement for 100% inspection of parts with automated measurement in the automotive industry with 3D measurement using the Equator system from Renishaw. Further, the article describes the essential characteristics of the device and its placement options in the workspace. The main theme deals with possibilities of processing the measured data gained in automatic mode.

Comparison of machining of poly-crystalline cubic boron nitride by rotary ultrasonic machi-ning and laser beam machining in terms of shape geometry
Kuruc, Marcel; Urminský, Ján; Necpal, Martin; Morovič, Ladislav; Peterka, Jozef
2015 - English
Poly-crystalline cubic boron nitride (PCBN) is the hardest material beside diamonds. Generally, so hard materials could not be machined by conventional machining technologies. For this purpose, advanced machining methods have been designed. Rotary ultrasonic machining (RUM) and laser beam machining (LBM) are included among them. This contribution investigate and compare these advanced methods during machining of PCBN. In experi-ments, a tool for friction stir welding (FSW) was manufactured. The main evaluated attributes was shape accuracy and dimension precision. When shape accuracy is not sufficient, welding process is negatively affected (lower tool life, improper weld parameters). And when dimensions of welding tool are different, it cannot be used for demanded sheet thickness. According to the performed experiments, RUM achieved good enough shape accuracy, but inadequate dimension properties. For LBM it was vice versa.

Methodology measuring geometry of the shank cutting tools
Pokorný, Peter; Zaujec, Rudolf; Buranský, Ivan
2015 - English
This paper focuses on geometry measuring of the shank cutting tools by the use of optical measuring devices. The scanning is realized in the system Atos Triplescan II and also in the system Zoller Genius 3. This paper provides a proposed methodology of shank cutting tools geometry measuring based on our scanning and measuring for the system Atos. The proposed methodology consists of the calibration, setting and tool clamping, preparation reference point and measuring in software. Part of the work also includes a comparison of measured results between the devices Atos and Zoller. This paper provides a contribution to the study of measurement geometry of the shank cutting tools.
