基于硬质合金开孔器对碳纤维复合材料的制孔
Drilling technology of carbon fiber reinforced plastic(CFRP) with carbide hole opener
摘要
Abstract
In order to avoid the hole defects of CFRP, the carbide hole opener was chosen. Under the same process parameters, the axial force and the quality of the outlet of two kinds of cutting tools were analyzed comparatively and the force in the process of drilling hole was discussed. The test results show that it is better to choose carbide hole opener to make hole of CFRP. Both the test and analysis show that: when the spindle speed is 5 000 r/min, and the feed rate is 150 mm/min, the quality of the outlet hole is relatively smooth with the carbide hole opener and there is almost no tear to appear. However, there is a little tear at the hole exit with the Brazed Diamond Core drill. Its collapse defect is more serious and the edge collapse factor is 0.10, compared with the former. At this time, compared with the hole wall roughness of 0.213 with the carbide hole opener, the hole wall roughness with the brazed diamond core drill is 0.621, which is coarser. Therefore the choice of hole making of CFRP with carbide hole opener is better.关键词
