Hard turning is used more and more frequently for finishing of precision hardened bores, namely for replacement of grinding. This paper studies the experimental results performed for qualifying of surfaces machined with hard boring. It presents the results of surface roughness measurements (2D, 3D) and indicates the changes occurring in the surface...
Article
Increases of quality of technical parts and whole products are not to be joined of course exclusively with the increase of accuracy but correlation is given up to a certain extent, particularly if the technical development during the 20th century is taken into consideration. This trend develops presently continuously further on because of the devel...
Article
The importance of metrology in general and especially of nanometrology for scientific research and especially for production engineering is described in this article and particularly the influence on technical development and high precision manufacturing but also for circumstances of human life is demonstrated. High accuracy measurement technique a...
Article
Intelligent metrology, quality assurance and quality management play an important and basic role in modern cost-effective customer-driven design and manufacturing. To meet market demands in present and future global industrial world, manufacturing enterprises must be flexible and agile enough to respond quickly to product demand changes. With suppo...
Article
Currently biomedical procedures are skill based to a wide extent and clinicians performance in this wide field of science is considerably variable. There are no scientific methods available to the biomedical and dental clinicians for measurement and feedback of the skill-based activities although some limited rules do exist to assist them in learni...
Conference Paper
To meet market demands in present and future global industrial world, manufacturing enterprises must be flexible and agile enough to quickly respond to product demand changes. With support of artificial intelligence and modern information technology it is possible to realize modern cost-effective customer-driven design and manufacturing taking into...
Article
This paper introduces the application of statistical analysis of workpiece geometry measurement results regarding the recently developed so-called “Skin-Model”. The “Skin-Model” presents a new description for Geometrical Product Specification and Verification (GPS) with its associated details and on its basis every workpiece can be geometrically de...
Article
Every company or manufacturer is facing an increased challenge to satisfy customer needs and all of criteria that its product must have. The days of mass producing standardized products for homogenous markets for long periods of time are quickly fading from memory. In this way one of important characteristics or features, which has to be considered...
Article
Quality management and metrology play an important and basic role in individual activities of different function enterprises in Multi-functions Integrated Factory MFIF to ensure the realisation of such systems. MFIF is an innovative concept and a new model for future enterprises which has been developed to meet the demands for cost-effective custom...

13.1 Úvod Povrch priemyselných súčiastok alebo obrobkov si môžeme predstaviť ako fyzickú hranicu medzi ob-robkom a okolitým prostredím. Reálny povrch obrobku definujú medzinárodné normy (ISO) ako sú-bor charakteristických vlastností, ktoré fyzicky existujú a oddeľujú vlastný obrobok od okolitého pro-stredia. Je chybné predpokladať, že povrch obrobk...

Choosing out of the machining process for the finishing process of machining of the parts requires great attention because by means of that the accuracy and quality requirements prescribed for the parts must be ensured. This paper analysis two processes, the grinding and the hard turning applied for finishing machining of hardened surfaces and pres...

... The characteristics, advantages, shortcomings and fields of application of contacting instruments have been described and reviewed extensively (e.g. [174] [209]), although the application of such instruments to biomedical applications [28] [169]), especially those involving soft surfaces, is relatively restricted. Contacting instruments with a large dynamic range, i.e. ...
... Zhang et al. [23][24][25][26] provided the theory of the GPS, GPS operation, and operator. Fengxia et al. [27][28][29][30][31][32][33][34] studied various problems in the geometric processing of products according to the GPS. ISO 1101 35 and ANSI Y14.5 36 also developed a related method for the evaluation of cylindricity errors. ...
