摘　　要：采用传统钻孔方法对GFRP(玻璃纤维增强材料)进行加工时易产生毛刺、撕裂和分层等缺陷,而螺旋铣孔方法可以有效避免这些缺陷产生。运用螺旋铣孔方法对GFRP进行制孔试验,得到切削速度、刀具公转转速、轴向进给螺距对孔壁表面粗糙度以及孔径尺寸误差的影响规律,对比分析了螺旋铣孔和钻孔的孔口缺陷。试验结果表明:影响孔壁表面粗糙度的切削参数由大至小依次为切削速度>刀具公转转速>轴向进给螺距;切削速度、刀具公转转速、轴向进给螺距与孔壁表面粗糙度均呈正比关系;影响孔径尺寸误差的切削参数依次为刀具公转转速>轴向进给螺距>切削速度;螺旋铣孔的入口侧缺陷较多,钻孔时的孔口缺陷更多出现在出口侧。When traditional drilling processes GFRP(glass fiber reinforced plastic),defects such as burrs,tears and delamination are very easy to occur,and the spiral milling method can effectively avoid these defects.The cutting test of spiral milling hole is carried out on GFRP by orthogonal and single-factor test methods,and the influence of cutting parameters on the surface roughness and hole diameter size error of the hole wall is obtained,and the orifice defects of spiral milling and drilling are compared and analyzed.The results show that the cutting parameters affecting the surface roughness of the hole wall are cutting speed,tool rotation speed and axial feed pitch from largest to smallest.The cutting speed,tool rotation speed and axial feed pitch are proportional to the surface roughness of the hole wall.The cutting parameters that affect the hole size error are tool rotation speed,axial feed pitch,cutting speed.There are more defects on the hole entry side of the spiral milling hole,while the hole mouth defects are more likely to occur on the hole exit side.
