“…This interest is attributed to their desirable mechanical properties, such as their high bending strength, metallic luster, effective conductivity, elevated hardness, robust corrosion resistance, substantial modulus of elasticity, superior resistance to crack propagation, and minimal thermal expansion [4,5]. The exceptional qualities of Zirconia have led to its widespread use in precision applications, particularly in the fields of medical implants and cell phone bodies [6]. The material's aesthetic appeal, exceptional hardness surpassing that of glass or plastic, near-complete resistance to corrosion, ability to be highly polished after shaping, and lighter weight compared to metals are not its only advantages [6].…”

This article explores the intricacies of micro-grinding parameter control for hard and brittle materials, with a specific focus on Zirconia ceramics (ZrO2) and Optical Glass (BK7). Given the increasing demand and application of these materials in various high-precision industries, this study aims to provide a comprehensive kinematic analysis of material removal during the micro-grinding process. According to the grinding parameters selected to be analyzed in this study, the ac-max values are between (9.55 nm ~ 67.58 nm). Theoretical modeling of the grinding force considering the brittle and ductile removal phase, frictional effects, the possibility of grit to cut materials, and grinding conditions is very important in order to control and optimize the surface grinding process. This research introduces novel models for predicting and optimizing micro-grinding forces effectively. The primary objective is to establish a micro-grinding force model that facilitates the easy manipulation of micro-grinding parameters, thereby optimizing the machining process for these challenging materials. Through experimental investigations conducted on Zirconia ceramics, the paper evaluates a mathematical model of the grinding force, highlighting its significance in predicting and controlling the forces involved in micro-grinding. The suggested model underwent thorough testing to assess its validity, revealing an accuracy with average variances of 6.616% for the normal force and 5.752% for the tangential force. Additionally, the study delves into the coefficient of friction within the grinding process, suggesting a novel frictional force model. This model is assessed through a series of experiments on Optical Glass BK7, aiming to accurately characterize the frictional forces at play during grinding. The empirical results obtained from both sets of experiments—on Zirconia ceramics and Optical Glass BK7—substantiate the efficacy of the proposed models. These findings confirm the models’ capability to accurately describe the force dynamics in the micro-grinding of hard and brittle materials. The research not only contributes to the theoretical understanding of micro-grinding processes but also offers practical insights for enhancing the efficiency and effectiveness of machining operations involving hard and brittle materials.

“…Yin et al [15], for example, devised a theoretical model to determine surface roughness and subsurface damage (SSD) depth. Sun et al [16] developed a surface topography model of ceramic materials for micro-grinding that takes into account grain distribution, dynamic impact, undeformed chip thickness, and the brittle material removal mechanism. Furthermore, Ma et al [17] created a force-thermal model based on wheel-gear geometry and material mechanism to forecast the grinding temperature field in an economical and effective manner.…”

For the purpose of optimizing grinding wheel profiles and grinding parameters, the prediction of the morphology of the grinding workpiece is essential. In this study, a new simulation model is developed to forecast the grinding workpiece surface morphology of ceramic material while accounting for the strain-rate effect. The effects of grinding parameters and patterned grinding wheel characteristics (e.g., grain geometry, grain size, grain protrusion height, and grain placement) on the surface and subsurface damage are explored.The results show that the simulation findings agree well with the theoretical approach, which takes the strainrate impact into account. Additionally, the magnitude of the change in surface roughness increases as the properties of the patterned grinding wheel grow, whereas the magnitude of the change in surface roughness reduces as the grinding parameters increase. Furthermore, the grinding parameters have a greater impact on subsurface damage than the patterned grinding wheel options.
