Abstract This work presents the development of an explicit/implicit particle finite element method (PFEM) for 2D modeling metal cutting processes. The purpose is to study efficiency implicit and explicit time integration schemes in terms precision, accuracy computing time. formulation marching developed, a detailed on solution steps presented. PFEM remeshing procedures insertion removal particl...

The aim of this research is to study the machinability aspects hardened AISI 4340 High Strength Low Alloy (HSLA) steel (50 ± 2 HRC (Hardness Rockwell C)). experimental investigation using coated carbide inserts carried out during dry hard milling process in a sustainable environment. input parameters are speed, feed rate and depth cut responses Average surface Roughness (Ra) Material Removal Ra...

In this study, the hardness and wear behaviour of carburized and boronized AISI 8620 steels have been studied. The boronizing treatment increased the hardness of AISI 8620 steels from 395 HV0.1 to a maximal 1610 HV0.1 compared to the carburized steels and also significantly improved its wear behaviour. From obtained results, it can be concluded that boronizing is very effective surface hardenin...
