摘　　要：玻璃作为脆性材料,在磨削加工中极易发生碎裂、崩边等问题。文章以石英玻璃和微晶玻璃为研究对象,开展超声/非超声下磨削加工多因素试验,分析了磨削力和表面粗糙度影响因素的主次顺序和最优加工参数,研究了加工方式和参数、材料差异对两种玻璃磨削力和表面粗糙度的影响规律。研究结果表明:石英玻璃和微晶玻璃的磨削力和粗糙度都基本呈现随着主轴转速提高而减小、随着磨削深度的增加而增大、随着进给速度的提高而增大的趋势;相对于石英玻璃,微晶玻璃在相同的加工参数和加工方式下的磨削力和表面粗糙度值更大;相对于非超声工况,超声都可以显著减小两种玻璃的磨削力并对降低表面粗糙度起到一定作用;但是,超声加工对于微晶玻璃的磨削力抑制和表面粗糙度降低效果更明显。研究可为玻璃材料高效加工提供数据支撑。As a brittle material,glass is prone to crack and edge collapse during grinding.This paper takes quartz glass and glass-ceramics as the research objects,carries out the multi-factor experiment of ultrasonic/non-ultrasonic grinding,analyzes the primary and secondary order of the factors affecting the grinding force and surface roughness and the optimal processing parameters,and studies the influence of the processing methods,parameters and material differences on the grinding force and surface roughness of the two kinds of glass.The results show that the grinding force and roughness of quartz glass and glass-ceramics basically decrease with the increase of spindle speed,increase with the increase of grinding depth,and increase with the increase of feed speed;Compared with quartz glass,the grinding force and surface roughness of glass-ceramics are larger under the same processing parameters and processing methods;Compared with non-ultrasonic working conditions,ultrasonic can significantly reduce the grinding force of two kinds of glass and play a certain role in reducing the surface roughness;However,ultrasonic machining can restrain the grinding force and reduce the surface roughness of glass-ceramics more obviously.The research can provide data support for efficient processing of glass materials.
