In this paper the influence of different machining parameters on the surface roughness, cutting force and material removal rate during turning process using MQLC (minimum quantity lubrication and cooling) system was investigated. The experimental plan was defined using Taguchi’s method. Orthogonal array L9 (34) was selected for four input par...

Spare parts are parts of machines, plants and equipment (technical systems) that should be available for replacement when canceling them for various reasons - breaks, abrasion and deformation. By replacing them, the observed technical system places itself in the possibility of functional use. In order to enable the possibility of eliminating failur...

In this paper, a model based on numerical solution of two ordinary differential equations is used to obtain the water level in the surge tank and the static pressure in the headrace tunnel – the properties of essential importance for the functioning of the water supply system during the turbine shut-off. The model allows a fast and reliable s...

Two different system modelling can be distinguished in life cycle assessment: attributional and consequential. Attributional modelling is used to describe the present state of the examined system and is characterised with use of allocation, no substitutions, market average suppliers, and cut-off principle. Consequential modelling is used to describ...
