There is a fine application prospect for multi-axis grinding of hard and brittle materials with diamond ball end tool. The effects of tool inclination angles and grinding modes of multi-axis grinding of quartz glass on the dynamic characteristics of the diamond abrasives, surface topography, surface fragmentation phenomenon, and surface roughness were investigated in this work. Material removal characteristics and surface formation conditions would be significantly affected by the effective cutting speed, material stress characteristics, and movement space path derived from different grinding modes and tool inclination angles. The surface texture direction is mainly determined by feed direction of the cutter and initial cutting moment and geometry feature of the engaged diamond abrasives. The surface fragmentation phenomenon of the formed surface is apparent when the corresponding surface roughness values are relatively larger. The machined surface with significant surface fragmentation phenomenon is mainly produced by materials' brittle fracture modes, such as larger positive lead and smaller negative tilt under conventional grinding and smaller negative lead angles and larger positive tilt angles under down grinding. Ideal surface evenness could be obtained by using lead or tilt 0° for conventional and down grinding. The ground surface with smaller surface roughness could be produced when employing tool postures, such as negative lead or positive tilt under conventional grinding and positive lead or negative tilt under down grinding condition.

使用金刚石球头刀具对硬质和脆性材料进行多轴研磨具有良好的应用前景。研究了刀具倾斜角度和石英玻璃多轴磨削方式对金刚石磨料动力学特性，表面形貌，表面破碎现象和表面粗糙度的影响。材料的去除特性和表面形成条件将受到有效切削速度，材料应力特性以及源自不同磨削模式和刀具倾斜角度的运动空间路径的显着影响。表面纹理方向主要取决于刀具的进给方向和初始切削力矩以及所接合的金刚石磨料的几何特征。当相应的表面粗糙度值相对较大时，形成的表面的表面碎裂现象是明显的。具有明显表面碎裂现象的机加工表面主要是由材料的脆性断裂模式产生的，例如较大的正值。铅和较小的负倾斜常规的研磨和较小的负下引线角和较大的正倾斜下向下磨削角。通过对常规和向下研磨使用铅或0°倾斜可以获得理想的表面均匀度。当采用工具姿态时，例如在常规磨削下为负铅或正倾斜，在向下磨削条件下为正铅或负倾斜，可以生产出具有较小表面粗糙度的地面。
