Decrease of surfaces roughness for parts processed with edge tool by improvement of the lathe working components uniform feed
Journal Title: Вісник Тернопільського національного технічного університету - Year 2017, Vol 88, Issue 4
Abstract
The relative motion smoothness of the tool and processing workpiece has an essential influence on the quality of the edge tool processing. The analyses of the process of the surface roughness formation on the parts processed with an edge tool under the influence of vibration movement of the metal-cutting lathes working components is carried out in this paper. The methods of prediction of the geometric parameters of the part surface quality are considered. It is determined here that the intensity of non-uniform metal-cutting lathe slide movement depends on the guide operating mode, that is, the conditions under which the friction of two surfaces occurs at their relative movement. Mixed friction influences the working components uniform motion the most negatively. In order to improve the uniform metal-cutting lathe support movement at light (fine) feeds it is suggested to go into guide dry (limiting) friction performing the processing with the additional loading of the working component. The results of the researches carried out under the working component loading connected with the influence of non-uniform support feed on the processed surface roughness are described. It was determined during the investigations that the stick-slip motion at light feeds of metal-cutting lathes working components is less intensive and the surface roughness of processed parts is improved
