“…The study related to [ 111 ] reported die-sinking EDM of bulk metallic glass where effects of peak current, pulse on time, and pulse off time on MRR and surface roughness were investigated. The study related to [ 110 ] reported on wire EDM of Zr57 BMG where effects of peak current was investigated on surface roughness. Although both are variations of EDM process, WEDM uses wire as a tool electrode and die-sinking EDM uses a cylindrical rod as electrode.…”

“…In addition, their process parameters, such as peak current, pulse on and pulse off time, were varied within different ranges. However, both studies reported on one common conclusion: with the increase in peak current and pulse duration, surface roughness showed an increasing trend, as shown in the Figure 24 [ 110 , 111 ].…”

Bulk metallic glasses (BMGs) are growing in popularity prominently due to their potential in micro-electromechanical systems (MEMSs) and aerospace applications. BMGs have unique mechanical properties, i.e., high strength, hardness, modulus of elasticity, and wear resistance, due to their disordered atomic structure. Due to their unique mechanical properties and amorphous structures, machining of BMGs remains a challenge. This paper aims to carry out a detailed literature review on various aspects of the machining of bulk metallic glasses using both conventional and non-conventional processes, including experimental approaches, modeling, statistical findings, challenges, and guidelines for machining this difficult-to-machine material. Conventional machining processes were found to be challenging for machining bulk metallic glasses due to their high hardness, brittleness, and tendency to convert their amorphous structure into a crystalline structure, especially at the machined surface and sub-surface. Although their high electrical conductivity makes them suitable for machining by non-conventional processes, they impose new challenges such as heat-affected zones and crystallization. Therefore, the successful machining of BMGs requires more in-depth analysis of cutting forces, tool wear, burr formation, surface finish, recast layers or heat-affected zones, crystallization, and mechanical property changes among different varieties of BMGs. This review paper provides guidelines emerging from in-depth analysis of previous studies, as well as offering directions for future research in the machining of BMGs.
