LASER BEAM INTERACTION WITH MATERIAL SURFACE

Jaroslav Rasa, Radka Bicistova
Keywords: internal energy of crystal lattice | material temperature | atomic oscillation | crystal lattice | Laser

The article describes the interaction of a laser beam with material surface, based on the oscillation of atoms in the crystal lattice, supposing that the oscillation amplitude is proportional to the temperature of the material. The principle of material removal using a laser beam is presented, along with its mathematical expression. The article also introduces a theory of laser beam interaction wit (…)

LEAD TIME REDUCTION METHODS

Ivana Simeonovova, Simeon Simeonov
Keywords: flow time | WIP | manufacturing system | lead time | Production Rate

This paper describes methods for reducing the lead time in manufacturing systems. In general, there are many methods for reduction of lead time, various methods are described in this article. For many manufacturing enterprises is shortening the lead time the difference between being part of the market and be in the first place in the production and sales of a specific product. It follows that this (…)

THE MORPHOLOGY CHANGE OF IRON DIBORIDE IN THE Fe-B ALLOY DURING DEFORMATION

Rostislav Choteborsky, Marie Kolarikova, Barbora Bryksi Stunova
Keywords: Hardness | Microstructure | Metal Matrix Composite | Iron Diboride

This research work studies the effect of deformation and destabilization heat treatment on morphology of the iron diborides of Fe-B cast alloy. The results show, that iron diborides change the morphology from continuous network to discontinuous, if the deformation is used. Relatively homogenous distribution of iron diborides is achieved, if the deformation is combined with destabilisation heat tre (…)

FACILITY MANAGEMENT AS INNOVATIVE TOOL FOR EFFECTIVE MANAGEMENT OF SUPPORTING COMPANY ACTIVITIES

Peter Poor, Nikol Kuchtova, Edvard Leeder, Martin Januska
Keywords: administration | efficiency | building | ProFM | facility management

In general, all organizations, whether public or private, use buildings, properties and services (support services) in order to support its core activities. By coordination of these assets and services; use of management skills and incorporation of various changes inenvironment; facility management (FM) affects its ability to act proactively and ensure all its requirements. The aim of FM is to str (…)
