On Cutting Force Coefficient Model with Respect to Tool Geometry and Tool Wear
(Elsevier Science Publishers B.V., 2015)
Cutting force models are important for machining processes simulations. This paper presents measurement of cutting forces during C45 (1.0503) carbon steel machining using a coated carbide tool. Various cutting edge geometries ...
ADVANCED THERMAL ERROR COMPENSATION OF A FLOOR TYPE MACHINING CENTRE ALLOWING FOR THE INFLUENCE OF INTERCHANGEABLE SPINDLE HEADS
(Ed. Inst. of the Wroclaw Board of Scientific Technical Societies Federation NOT, 2015)
This paper is a continuation of scientific work on the modelling of complex MT thermal behaviour using a dynamic method with a physical basis: thermal transfer functions. Previously published works focusing on middle-sized ...
Control of hybrid electric-hydraulic drive for vertical feed axes of machine tools
(MM Science Journal, 2019)
This paper deals with methods to reduce the influence of gravitational force on machine tool vertical feed axes. It provides an overview of existing counterbalancing mechanisms that are used in industrial applications. The ...
Metallurgical Aspects of Laser Surface Processing of PM Cr-V Ledeburitic Steel
(Hindawi Publishing Corporation, 2011)
The Vanadis 6 ledeburitic-type steel was laser surface remelted. Microstructural changes and hardness in laser affected material were investigated using light microscopy, SEM, and EDS-microanalysis. It was found that the ...
MACHINE TOOL VIBRATION REDUCTION USING HYDROSTATIC GUIDEWAY
(MM Science Journal, 2018)
Utility properties of the machine tools, such as machining accuracy, surface quality, and productivity are affected by many factors that also include guideway properties. Guideways enable machine tool parts to move. It is ...
Real-time compensation of Machine Tool Thermal Errors Including Cutting Process
(Ed. Inst. of the Wroclaw Board of Scientific Technical Societies Federation NOT, 2015)
This paper presents a real-time compensation of three-axis vertical milling centre thermal errors including the cutting process effect. The simulation is based on dynamic modelling using transfer functions. The model was ...
