    Face milling with a round insert at various cutting speeds and feed rates
    (Національний технічний університет "Харківський політехнічний інститут", 2019) Makkai, Tamas; Kundrak, Janos; Karkalos, Nikolaos E.; Markopoulos, Angelos P.
    Face milling is frequently used for the rendering of flat surfaces with a high degree of precision. With this machining process, high material removal rate is possible to be attained but management of cutting forces values is also desirable, in order to avoid excessive power consumption, tool wear or vibrations. This can be achieved by selecting the process parameters within an appropriate range for each case. In the present study, an experimental investigation is conducted with a view to determine the effect of two important process parameters, namely cutting speed and feed on the cutting forces and the specific cutting forces during face milling, in cases where a round insert is used.

    Influence of depth of cut and cutting speed on cutting forces in face milling under constant chip cross-section conditions
    (Національний технічний університет "Харківський політехнічний інститут", 2019) Karkalos, Nikolaos E.; Markopoulos, Angelos P.; Makkai, Tamas; Kundrak, Janos
    In various high-end industries such as the automotive and the aerospace industry, face milling is one of the most preferred solutions for the fabrication of flat surfaces with high quality. During machining it is desired to achieve the required result with high efficiency. However, attention should be paid so that forces are kept within acceptable limits for maintaining energy consumption and loading of machine tool at relatively low levels. Thus, it is important to determine the influence of process conditions, such as depth of cut or cutting speed, on cutting forces. In this study, this is attempted by conducting experiments at two different depths of cut and four different cutting speeds for cases with the same chip cross-section value. After analysis of obtained results, useful conclusions on the influence of these parameters on cutting forces are presented.
