摘　　要：为了改善和抑制干切削下的石英增强聚酰亚胺复合材料的加工缺陷,对该材料进行超低温冷却铣削加工,并针对常规干切削缺陷,对比分析复合材料加工形貌、表面粗糙度值和刀具磨损以及切削区温度等性能。结果表明:相对于干切削且不同切削速度条件下,超低温冷却能够有效抑制低速干切削石英纤维起毛和高速干切削聚酰亚胺黏结剂的烧蚀缺陷,加工表面质量都得到有效改善,加工表面粗糙度随切深的增加呈先降低后增大趋势;刀具耐用度获得明显提高。In order to improve and inhibit the processing defects of quartz reinforced polyimide composite dry machining,cryogenic cooling milling is conducted,and regarding the conventional flaws of dry milling,the cutting properties including surface morphology,roughness and tool wear are compared and analyzed.The results show that the cryogenic cooling milling at different cutting speeds can effectively inhibit the fiber fluff at low speed dry cutting and the ablative defects of adhesives at high speed dry cutting,thus the surface quality being upgraded effectively,the surface roughness decreases first and then increases with the increase of cutting depth,and the tool durability significantly improves.
