中文摘要：

通过微磨料空气射流加工普通平板玻璃的试验研究，分析了加工时间、空气压力、磨料流量、喷射距离、喷射角度、磨料种类、喷嘴结构和尺寸等加工工艺参数与微磨料空气射流加工的材料冲蚀率及玻璃表面冲蚀加工凹坑尺寸（凹坑直径和凹坑深度）之间的关系，得出了这些工艺参数对微磨料空气射流加工效果的影响规律。结果表明：喷射距离对材料冲蚀率和冲蚀凹坑的尺寸影响最大，存在一个可以获得最大冲蚀率和加工深度的最佳喷射距离；喷嘴的形状、尺寸和喷射角度的不同直接改变加工凹坑的轮廓，是影响微磨料空气射流加工轮廓结构形状的关键因素。

英文摘要：

There are several parameters that have been claimed to have a significant effects on the micro abrasive jet machining（MAJM） process： air pressure, mass flow rate, nozzle distance to target material, machining time, impacting angle, nozzle shape and size, abrasive, etc. Based on the experimental study of MAJM for glass, the influences of these technical parameters on material erosion rate and the shape of the eroding dimple were investigated, and the basic technical laws of these effects on machining performance for MAJM were obtained. The results indicate that the nozzle distance to target material is the most prominent factor for material erosion rate and structure size of eroding dimple, there is an optimum distance to get maximum erosion rate and machining depth. The nozzle type and impacting angle are the key parameters for the dimple structure profile, directly changing the shape of machining dimples.
