ENERGY ANALYSIS OF ENERGY HARVESTING FROM MACHINE TOOL VIBRATIONS

Zdenek Hadas, Michal Holub, Petr Blecha, Jan Vetiska, Vladislav Singule
Keywords: energy harvesting | machine-tools | vibration | milling | diagnostics

This contribution assesses the possibilities of application of Energy Harvesting technology in the field of machine tool diagnostics. These machines are on various parts more often fixed with many sensors monitoring status values such as deformations or temperature. However, in poorly accessible construction nodes, there is a problem with installation of both power and data cables. It could be solved by (…)

ON THE ANALYSIS OF THE SOUND SPECTRUM AT MACHINING OF THE GLASS-POLYESTER COMPOSITE MATERIAL

Zdenek Fiala, Miroslav Piska, Ales Jaros
Keywords: sound spectrum | dominant frequency | composite material | specific cutting force | flank wear | cutting tool

This paper deals with analysis of the machining process sound spectrum at milling of the glass-polyester composite material. The development of intensities of the machining process with a growing flank wear has been observed during the experimental machining. High speed steel cutting tools deposited by (Al,Ti,Cr)N coating were used for experimental machining. The goal of this article is identifying re (…)

APPLICATION OF COMPUTER SIMULATION TO INCREASE THE PRODUCTION RATE OF PICKLING LINE

Ivana Simeonovova, Radek Knoflicek
Keywords: production system | Simulation | optimization | simulation analysis | pickling line | Production Rate

This article describes the practical application of computer simulation of the manufacturing system. The field of modelling and simulation is as diverse as a group of people. Each discipline has developed or is developing its own models and their own approaches and tools for exploring these models. The simulation includes generating and observation of artificial history of system, whereby is possible to (…)
