摘　　要：选择钢化玻璃为硬脆材料的代表,利用旋转超声技术对钢化玻璃进行表面加工测试,以此实现对超声辅助旋钻微孔加工参数优化,同时选择正交试验的方法选择最优参数条件。研究结果表明:影响微孔直径尺寸的因素按照重要性排列为加载力,超声功率,游离磨料尺寸大小。影响微孔深度的因素重要性顺序是超声功率、游离磨料大小与加载力。确定最优方案:加载力等于0.7N,游离磨料外径尺寸3μm,设置的超声功率比例等于70%。随着加载力提高后,以较低超声功率进行处理时,形成了尺寸很小的微孔直径,并且孔深度也明显缩短;当设置较低加载力与较高超声功率时,形成了更大深度微孔,同时直径也明显增加。该研究对提高硬脆材料的微孔质量以及加工效率具有很好的实际指导意义,易于推广应用。The toughened glass was selected as the representative of hard and brittle materials,and the surface processing of toughened glass was tested by the rotary ultrasonic technology,which can realize the optimization of ultrasonic assisted rotary drilling micro-hole processing parameters,and the orthogonal test method was used to select the optimal parameter conditions.The results show that the factors affecting the diameter of micropores are listed as loading force,the ultrasonic power and free abrasive size in order of importance.The order of importance of the factors affecting the depth of micropores is ultrasonic power,free abrasive size and loading force.The optimal scheme was determined as follows:the loading force was equal to 0.7N,the outer diameter of free abrasive was 3μm,and the ultrasonic power ratio was equal to 70%.With the increase of the loading force,the micropore diameter is very small and the pore depth is obviously shortened when the ultrasonic power is used to treat it.When setting low loading force and high ultrasonic power,larger depth of micropores are formed,and the diameter of micropores is also significantly increased.This research has a good practical guiding significance for improving the quality of micropores and processing efficiency of hard and brittle materials,and is easy to be popularized and applied.
