“…Yin et al (2017) [ 88 ] investigated grinding force ratio, surface roughness, and the material removal mechanism involved in micro-grinding of Zr-based metallic glass (BMG C Zr 70 Ni 10 Cu 20 ) 82 Ta 8 Al 10 and BMG D Zr 55 Cu 30 Ni 5 Al 10 ). They reported a decreased value of micro-grinding force with increased spindle speed.…”

“…An empirical model based on the simple single factor test, as proposed by this study, demonstrated optimum grinding parameters (grinding depth of cut of 6 μm, spindle speed of 60,000 rpm, and the workpiece feed rate of 20 μm) for achieving the best surface quality in BMG. A grindability study of BMG c , BMG d , and conventional polycrystalline metallic (brass H62) reported the highest micro-grinding force for BMG c and the lowest force for the brass H62, as shown in Figure 16 [ 88 ]. This is due to the fact that brass H62 has the lowest hardness as well as better plasticity both in hot and cold states.…”

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.

In high-speed and heat-stressed processes, the cutting force is a determining parameter of surface quality. The existing studies of the cutting force in microgrinding are experimental and their results are valid for a narrow range of the processed material. The paper describes the experimental study of strength when microgrinding complex alloy steel. The obtained results allow to expand the field of use of micro-grinding technology applied to metal materials.
