STRATEGY OF MILLING CENTER THERMAL ERROR COMPENSATION USING A TRANSFER FUNCTION MODEL AND ITS VALIDATION OUTSIDE OF CALIBRATION RANGE
(MM Publishing, 2019)
Achieving high workpiece accuracy is a long-term goal of machine tool designers. There are many causes of workpiece inaccuracy, with thermal errors being the most dominant. Indirect compensation (using predictive models) ...
Effects of Wet Separated and High Speed Milling Fly Ash Added in High Volume to Cementitious Materials
(BUDAPEST UNIV TECHNOLOGY ECONOMICS, PERIODICA POLYTECHNICA CIVIL ENGINEERING, 2020)
In this research high speed milling was carried out on particles of brown coal raw fly ash, on second layer, and on third layer particles obtained from wet separation of brown coal raw fly ash. Due to milling process, ...
Set of geometric errors evaluation based on R-test measurement
(MM Publishing, 2019)
Presented paper deals with the development of a procedure for fast measurement and evaluation of the set of basic geometric errors of the five-axis milling machines. Based on R-test measurement a rotary axes pivot point ...
Analysis of cutting parameters in point machining of parts with complex shape
(ČVUT v Praze, fakulta strojní, 2018)
This paper presents developed SW module in the postprocessor, which is designed to backward analysis of CAM milling toolpath.
The module is designed to analyze multi-axis finishing machining of complex shape parts with ...
Improvement of Machining Thin-Walled Parts Generated by Hybrid Manufacturing Using Optimalized Support
(ČVUT v Praze, fakulta strojní, 2018)
This paper is intended to show the problem in the production of thin-walled parts using hybrid manufacturing. It is necessary to machine the parts generated by 3D printing at certain stages of the production process. The ...
Design of two - axis controlled damper to suppress vibration of long slim rams
(ČVUT v Praze, fakulta strojní, 2018)
The contribution deals with the design of two-axis controlled damper to suppress vibration of long slim rams of larger cross-section. Proposed concept is based on a demand to damp down lowest (bending) eigenmodes of the ...
The impact of communism on the history of computer development in Eastern Europe.
(NAACE, 2019)
The article deals with the history of computer technology in Czechoslovakia in the years 1945 - 1989. It is easier to describe not only significant projects but also to capture the problems of computer technology in ...
Effect of Stress Induced Anisotropy on the Noise of Ring-core Fluxgate
(IEEE, 2015)
In this paper we show how an anisotropy perpendicular to the direction of excitation is favourable to obtain low noise in fluxgate sensors. We produced ring cores by electroplating NiFe thin film (6 μm) over a bended copper ...
AMR Proximity Sensor With Inherent Demodulation
(IEEE Sensors Council, 2014)
Our novel position sensor is based on the combination of the eddy-current and permeability effects. The primary field is excited by a coil, but instead of induction coil, the sensing part uses anisotropic magnetoresistor ...
The nature of alarm communication in Constrictotermes cyphergaster (Blattodea: Termitoidea: Termitidae): the integration of chemical and vibroacoustic signals
(Company of Biologists Ltd., 2015)
Alarm signalling is of paramount importance to communication in all
social insects. In termites, vibroacoustic and chemical alarm signalling
are bound to operate synergistically but have never been studied
simultaneously ...
