The results show that the surface microphotograph yielded in multiple-step machining with slow feeding and in one-step compound process is satisfactory, and there are fewer defects, lower deformation and thinner metamorphic layers; while that produced in other processes is quite rough, there are more defects and bigger deformation on the machined surface, and they are detrimental to assembly properties and fatigue life of fastening holes.

结果表明，钻扩铰多步慢进给工艺和一步复合制孔工艺所加工出的表面，平整、光滑、加工缺陷少、晶格变形小、变质层薄；而其它工艺条件下，孔表面微观形貌复杂、加工纹路紊乱、表面缺陷多、晶格畸变大，变质层厚，这些加工状况，对紧固孔的装配性能和疲劳寿命都有很大的影响。
