Cf/SiC复合材料微小孔的钻削加工特性
Drilling Characteristics of Micro Holes on Cf/SiC Composites
摘要
Abstract
Diamond drills were used to drill holes of 0.5 mm diameter on Cf/SiC composite materi-als in vertical direction and parallel direction to the fiber weaving.The effects of drilling method and processing parameters on drilling forces,hole quality and tool wear were investigated.Material re-moval mechanism and tool wear mechanism were studied.The results show that vertical drilling has 30％greater thrust forces,8％less hole damage factor,20％greater roundness errors,and less tool wear rate than those of parallel drilling.Delamination defects result in smaller surface roughness of hole walls for parallel drilling than those of vertical drilling.The FOA has a significant impact on the material removal mechanism:when FOA is as 0° to 90°,the carbon fibers undergo shear fracture re-sulting in better surface quality;when FOA is as 90° to 180°,the carbon fibers undergo bending frac-ture leading to poorer surface quality.关键词
