Sejčas bol'šinstvo škol'nikov ne imejut 100%nogo zdorov'ja, poetomu problema ochrany zdorov'ja detej stoyt očen' ostro. Na urokach truda škol'niki učatsja berech' svoye zdorov'ye v povsednevnoj žizni (uchatsja pravil'no pitat'sja, sobljudat' pravila lichnoj gigiyeny i t.d.). Eto javljayetsja važnym aspektom ich dal'nejshej vzrosloj žizni. Now, most schoolchildren do not have a one hundred percent health, so the problem of children's health is very serious. At lessons of work pupils learn to take care of their health in everyday life (learn to eat right, observe good personal hygiene, etc.). It is further important aspect of their adult life.

Detection of deformation zones when machining nickel alloys
Czán, Andrej; Šajgalík, Michal; Drbúl, Mário; Holubják, Jozef; Kordík, Marek; Rákoci, Jozef
2015 - English
Processes in cutting zone are so complicated and dynamic, that their definition is performed by specific created models. Innovative measurement methods of the process can be used to improve and verify the accuracy of these models. With these methods, there are many sources of error when using empirical or exact methods such as infrared radiation thermography to measure the temperature distribution of the tool, workpiece, and chip during metal cutting. Furthermore, metal cutting presents unique measurement challenges due to factors such as the high magnification required, high surface speeds and deformations, microblackbody effects, changing emissivity, and primary, secondary and tertiary deformations. To better understanding of phenomena in deformation zones and detection of them is necessary to know the greatest number of measurable factors, which affect the cutting process. In experiments, there were performed the measuring of temperature and its distribution, ratios of cutting forces and monitoring of deformation processes using by high-speed optical scanning system. These measurements were performed by multifunctional system which allow to measure and monitor all required factors simultaneously. The outputs from this multimeasuring system are the basis for verification of theoretical knowledge from this field and elimination of the uncertainties that arise with computational simulation systems.

Use and influences of CAx technologies on the components production cycle
Milde, Ján; Pokorný, Peter
2015 - English
This thesis focuses on the use and influences of CAx Technologies on component production cycle. At the same time it lists and describes computer aided technologies that deals with this subject.
This thesis identifies basic medical and stomatology concepts as well as methods used. It also contains a detailed example of manufacturing medical implants such as knee implant or dental crown. It further explains the detailed process of acquiring a digital description of implant shape and its subsequent modification. Attention is drawn to a analysis of ultrasonic machine ULTRASONIC 20 linear, which was used for manufacturing of dental bridge. In the centre of Excellence 5-axis machining in Trnava, where we manufactured a hip implant. The fabrication was accomplished by 4 - and 5 - axis kinematic structures of machining by the Eagle machine.
The last part of this thesis concentrates on the rapid protoyping technologies and comparating of direct and indirect methods of manufacturing of medical components.

Significance of magnetizing voltage on barkhausen noise emission of hard milled surfaces
Neslušan, Miroslav; Hrabovský, Tomáš; Jančovič, Peter; Mičieta, Branislav
2015 - English
This paper deals with the non-destructive evaluation of surface made of hardened roll bearing steel after hard milling via Barkhausen noise technique. The paper discusses significance of magnetization voltage on Barkhausen noise (BN) emission and the corresponding BN features such as Peak Position, FWHM and the shape of BN envelope. BN emission is linked with variable flank wear of cutting tool. Effective value of BN, FWHM and Peak Position derived from the raw BN signal as well as BN envelopes are compared with metallographic observations and theoretical background about magnetic domains reconfiguration when the near surface undergoes severe plastic deformation at elevated temperatures. The results show that magnetization voltage takes significant role in magnitude of BN, shape of BN envelope as well as asymmetry of BN emission during cyclic magnetization.

Determination of the optical 3D scanner capability of measuring a geometric characteristic
Vagovský, Juraj; Görög, Augustín; Buranský, Ivan
2015 - English
The measurement system analysis is a part of the quality assurance. In this field, the measuring device capability evaluation has an importance. Optical 3D scanner, as a noncontact device, is used for digitization and measuring. Aim of this paper is point to the possibility of measuring a small object, namely hard metal rod, using optical scanner. The issue was the evaluation of measuring capability of the GOM ATOS Triple Scan II optical 3D scanner when measuring the geometric characteristic of runout with using of various measuring volumes. Measuring of a small object is often difficult due to ensuring the measuring repeatability (precision) and high accuracy. Statistical method of repeatability of measurements was used for capability evaluation and for its expression in the form of capability indices. Based on the results it was able to confirm or refute the capability of this scanner to provide relevant data during measuring a small object.
