Документ Comparison of finish machining procedures on the basis of material removal performance(НТУ "ХПИ", 2011) Kundrak, Janos; Deszpoth, I.It is suitable to compare the economy of procedures so much different in material removal – like abrasive machining and machining with edges – on the basis of material removal rates. The comparison of different hard cutting procedures was carried out in compliance with the evaluation criteria that were the quality requirements in producing the workpieces. In this paper the economic efficiency of the machining procedures – grinding, turning, and combined procedures – is analysed on the basis of the machining times, the surface rate and the material removal rate.Документ The efficiency of combined machinings(НТУ "ХПІ", 2012) Kundrák, J.; Gyáni, K.; Deszpoth, I.This paper analyses the efficiency of the finish process applied in machining of hard surfaces, completed by grinding, hard turning and also by the combination of these two procedures, on the basis of time consumption.Документ Material removal characteristics in rotational and tangential turning(НТУ "ХПІ", 2012) Kundrák, J.; Gyáni, K.; Deszpoth, I.; Sztankovics, I.Rotational and tangential turnings are two special variants of hard turning. They can eliminate a disadvantageous characteristic of ordinary hard turning, namely, the generation of periodical topography. This study reveals common and different features of both rotational method and the long-known tangential turning method. Common features make the complex chip removal mechanism of rotational turning easier to understand. The calculation of chip thickness and width becomes simpler. However, while the cutting technical parameters can be drawn on planar surfaces in a tangential method, these parameters obtain a 3D spatial form in rotational turning due to the helical edge. The extremely high productivity of rotational turning and the kinematical relations of the machining system are illustrated by several examples. Both methods are supplementary solutions because their extensive use requires expensive tools, which result in economic problems.
