In view of the problem that various fused silica materials have different characteristics, which could cause differences in processability, the mechanical properties of fused silica materials were studied through nanoindentation experiments. Relationship curves between indentation load and material hardness/elastic modulus were obtained for different fused silica optics. The fracture characteristics of fused silica materials were also studied using the gradient force imprinting method, and the fracture toughness and critical load of crack generation were calculated for different fused silica materials. The ability of different fused silica materials to resist crack instability propagation under the same process conditions was also clarified. Furthermore, the polishing removal characteristics of fused silica materials were researched, and the polishing removal efficiency of different materials was obtained through the magnetorheologi cal finishing (MRF) spotting method. It was further verified that the hardness was positively correlated with the material polishing removal efficiency. Based on the characteristics of different fused silica materials, the optical ultra -precision processing parameters could be selected. This is of great significance for low-defect and high-efficiency ultra-precision machining of optics.

“…CMP can realize the smooth and flat processing of GaN crystals, but its efficiency needs to be improved further. Magnetorheological finishing is a non-damage processing technology [21][22][23][24][25], which can effectively realize sub-nanometer processing of hard and brittle crystal materials such as sapphire [26,27], silicon carbide [28,29], and optical glass [30][31][32]. However, research on GaN magnetorheological finishing has not been reported.…”

High-quality and high-efficiency processing of gallium nitride (GaN) crystals is urgently required for optoelectronic communications and other major industries. This study proposes a novel high-efficiency non-damage magnetorheological chemical polishing (MCP) process to overcome the existing problems of low efficiency and lattice distortion during processing. The effects of the MCP fluid composition and key processing parameters on the surface roughness and material removal rate (MRR）of GaN crystals were studied experimentally. The results showed that a compounded abrasive containing silica fluid exhibited better polishing effects than a single abrasive. The polishing efficiency could be improved by adding NaOH solid particles, and the MRR reached 13.19 nm min-1 when the pH of the MCP fluid was 10. The MRR increased gradually with an increase in the pole rotation speed and worktable speed and a decrease in the polishing gap. The surface roughness of the GaN crystals was improved from Ra 115 nm to Ra 0.375 nm after polishing for 4 h. The surface and sub-surface damage of the polished GaN crystals was analyzed using scanning electron microscope (SEM) and transmission electron microscope (TEM). The results confirmed that the MCP process can realize the non-damage polishing of GaN crystals. Moreover, a prediction model for the surface roughness of GaN crystals in the MCP process was constructed. The overall difference between the actual and predicted surface roughness values for the model was 11.6%.

“…Although some research has been carried out on polishing cutting inserts, no single study exists which provides a batch polishing machine for smoothing ank, nose, and edge simultaneously with nanometer scale surface roughness. Meanwhile, other mainstream polishing methods such as bonnet polishing [37][38], uid jet polishing [39][40] and magnetorheological nishing [41][42] are not suitable for the polishing of cutting inserts due to the high equipment cost and polishing cost. This paper presents a novel method, called 'magnetic eld-assisted batch polishing (MABP)', for automatic batch polishing cutting inserts simultaneously, together with nanometer scale surface nish.…”

To reduce tool wear of inserts in cutting, this study presents an emerging magnetic field-assisted batch polishing (MABP) method for simultaneously polishing multiple ceramics cutting inserts. The wear characteristics are clarified by cutting S136H steel. The surface roughness in regard to mean height (\(Sa\)) at the flank face, edge, and nose has achieved below 2.5 nm, 6.25 nm, and 45.8 nm, respectively after 15 minutes of polishing, and the tool life was extended by 175%. The experimental results indicate that MABP is an effective method for mass polishing the cutting inserts, and the polished surfaces can notably reduce tool wear.
