Документ Efficiency of material removal and machining in cutting(Національний технічний університет "Харківський політехнічний інститут", 2020) Molnár, Viktor; Deszpoth, István; Kundrák, János; Markopoulos, Angelos P.Among the methods and parameters used for analyzing the productivity of machining procedures, this paper deals with an analysis based on the efficiency (material volume removed in unit time) of material removal. The paper focuses on how this specific indicator, the material removal rate (MRR), changes when different machining procedures and production sub-phases are considered.Документ Effect of cutting data selection on productivity in face milling(НТУ "ХПІ", 2018) Kundrák, János; Molnár, Viktor; Deszpoth, István; Makkai, TamásFace milling as a cutting procedure is used for high productivity manufacturing of prismatic components. In the automotive industry, characterized by mass production, the enhancement of productivity is a primary goal for manufacturing companies. There is a wide range of methods for increasing productivity. This paper analyses how productivity can be increased by the mach ining time, material removal rate and surface rate by choosing the appropriate cutting data. Cutting experiments were carried out for machining prismatic components and the change in machining time was analysed. It was proved that within the performance limits of the WGMT (Workpiece – Gadget – Machine – Tool) system a significant amount of manufacturing time and therefore cost can be saved while the geometric accuracy and surface quality of the component remain as specified in the blueprint.Документ Investigation of cutting force in face milling(НТУ "ХПІ", 2017) Kundrák, János; Makkai, Tamás; Deszpoth, István; Nagy, AntalThe increase of cutting applied in finishing processes can be achieved first of all by increasing the cutting speed and feed. In face milling, if feed fz per tooth is increased and/or the shape of the chip cross section is changed, the load of the cutting edges changes and influences the cutting forces and the actual efficiency. In this paper, the cutting force arising in chip removal and changing under the influence of the increased feed is analysed.
