The article presents the results of research on the wear of the cutting tool in the process of high feed milling and plunge milling of the Inconel 718 alloy. A specially designed milling head was used in the study, allowing both of the previously mentioned milling methods to be implemented with a single tool. Ceramic inserts CNGN120712 in versions CS300 and CW100 were used for the research. During...
A procedure for assessing the properties of a milling machine based on machining tests was presented, with particular emphasis on shape errors and properties of the workpiece surface layer. The selection of an appropriate test-piece and cutting parameters for such a test was discussed. A mathematical formula was also presented, which allows to associate the accuracy of the test-piece with that of...
Statistical studies of the surface distribution of milled workpieces and the possibility of their use for operationbased tests and machine tool evaluation were presented. In the first part of the paper, the assumptions and scope of statistical research were defined and the method of obtaining data on machined surfaces directly from machining programs was described. In the following part of the article,...
The paper describes the problem of tool wear in machining processes. The importance of determining and analysing the demand of machining centres for electricity was emphasised and the potential relationship between tool wear and machine energy consumption was indicated. The paper presents the results of the measurements of cutting tool wear on the energy consumption of a machining centre based on...
Przedstawiono ocenę energochłonności pionowego centrum frezarskiego VF-7/50. Wykonano badania w celu zebrania danych na temat zapotrzebowania obrabiarki na energię elektryczną. Opracowano zależność, na podstawie której można określić energochłonność obrabiarki w procesie frezowania. Wyniki zweryfikowano eksperymentalnie.
Przedstawiono opracowaną metodę identyfikacji sygnału z analizatora sieci zasilania na przykładzie frezarki sterowanej numerycznie. Otrzymane wyniki umożliwiają obserwację wpływu zużywających się ostrzy skrawających na wartość mocy pobieranej przez obrabiarkę z sieci w trakcie realizowania na niej różnych zabiegów.
The article discusses the importance of energy consumption for the modern machine tool. The research was carried out to show the influence of various cutting factors and parameters on the power consumption values of the machine tool. A special algorithm was developed to determine the actual energy consumption of the machine tool during the cutting process. The results of the study were compared with...
