“…Work pieces with high accuracy are usually obtained by grinding. A novel approach of single grain scratching/grinding is proposed at nanoscale depth of cut and m/s, which is three to six orders magnitude higher than present nano-scratching (Wang et al, 2018a(Wang et al, , 2018b. A new model of maximum undeformed chip thickness is suggested, which is in good agreement with the grinding results on hard and soft-brittle materials (Zhang et al, 2012a(Zhang et al, , 2012b(Zhang et al, , 2012c.…”

Purpose The purpose of this study is to investigate the characteristic and function of oxide film formed on grinding wheel in electrolytic in-process dressing (ELID) precision grinding and improve the quality of ELID grinding. Design/methodology/approach Dynamic film forming experiments were carried out with a simulation device close to the actual processing conditions. Then, the ELID grinding experiments of bearing rings were performed using grinding wheels with good film forming effect. The experiment was designed by quadratic regression general rotation combination method. The influence of grinding depth, electrolytic voltage, duty cycle and grinding wheel linear speed on grinding effect is analyzed. Findings A mathematical model for the formation rate of oxide film was established. The experiments show that the composition of grinding wheel and grinding fluid, as well as the electrical parameters, influence the film forming effect. Thus, the oxide film plays an important role in ELID grinding. Originality/value This study provides a reference for the design and selection of grinding wheel and grinding fluid and the setting of process parameters in ELID grinding.

“…Dai et al [14] optimized the process parameters of ELID grinding RB-SiC ceramics and obtained high-quality mirrors with surface roughness less than 0.8nm. The electrolytic grinding fluid used in ELID grinding is easy to cause corrosion of the machine tool and contamination of the workpiece processing surface, which is not conducive to the green manufacturing of optical components [15]. Cao et al [16] explored the deformation and fracture removal mechanism of ultrasonic vibration assisted grinding of silicon carbide ceramic materials.…”

Electrical discharge grinding technology (EDGT) is an efficient and high precision method for machining RB-SiC ceramic materials. In this paper, the mechanism of material removal in EDGT is deeply studied, and the formation characteristics of surface topography under different material removal methods affected by grinding depth are analyzed. A three-dimensional heat conduction analysis model in the process of single pulse discharge was established, and the temperature field distribution in RB-SiC ceramic material under different discharge energy was obtained by numerical calculation. It is found that the simulated crater radius and depth increase with the increase of the discharge time, and the material removal amount gradually increases, but the growth rate gradually decreases. In order to give full play to the advantages of EDGT, the discharge energy and grinding depth were optimized according to the material removal mechanism. Finally, RB-SiC ceramic machining experiments were carried out using the optimized machining parameters, and a smooth surface with few discharge craters was obtained. It is found that the grinding scratches on the material surface are mainly plastic grinding, and the material surface roughness is 0.443 µm. The research results of this paper can provide guidance for engineering practice of ductile grinding technology of RB-SiC ceramic materials.
