杯形砂轮磨削熔融石英玻璃机理与实验研究
Mechanism and Experimental Study on Grinding of Fused Silica Glass with Cup Grinding Wheel

熔融石英玻璃是一种工程领域常用的光学玻璃材料。针对在陶瓷材料端面快速磨削中具有广泛应用的杯形砂轮，综合考虑了磨削过程中的脆性断裂和对材料造成的冲击效应，基于单颗粒磨削理论对砂轮运动轨迹和去除效率理论建模分析。在此基础上，对熔融石英玻璃材料进行多参数的单颗粒金刚石刻划实验，以验证理论预测模型，实际测得的磨削力数值与刻划后三维表面形貌，与理论分析结果吻合。结果表明，这一理论模型可以用于预测磨削力数值和优化加工参数。
Fused silica glass is a kind of optical glass materials commonly used in engineering field. Cup grinding wheel is widely used in surface grinding of hard and brittle materials, considering brittle fracture and impact effect on materials in grinding, the analysis and modeling of the grinding wheel trajectory and removal efficiency are carried out based on the theory of single particle grinding. The single parameter test of fused silica glass materials with multiple parameters is performed to verify the prediction model. The measured values of the grinding force and the surface topography are well in an agreement with the analyzed. The experiments show that the tmodel can be used to predict the grinding force and optimize the grinding parameters
