Özet

© 2022 Gazi Universitesi Muhendislik-Mimarlik. All rights reserved.In this study, the machining characterization properties (namely, cutting power Pc, specific cutting energy ps and surface roughness Ra) of AISI 8740 steel, which is used in high strength applications in the industry but do not have information about its machining characteristics in literature, were found experimentally for different machining parameters (feed per tooth (uncut chip thickness) fz and up- and-down-milling processes). The electric current measurements taken during non-cutting (idle) and cutting conditions were used in power calculations under different machining conditions. It was found that the ps decreased and Ra increased with increasing fz in the up-and down-milling operations and the lower Pc, ps and Ra values were obtained in down-milling than the up-milling operations. The ps values of the material was in between 7.1- 15.7 Ws/mm3 for the machining settings used in this study.
