摘要:为了提高碳纤维复合材料(CFRP)的制孔质量,对CFRP旋刨刀的几何结构进行设计。基于旋刨刀的前角为15°,利用有限元分析软件ABAQUS的explicit子模块,建立CFRP旋刨制孔的三维模型,分析仿真过程中的轴向力和孔的出口质量。在相同条件下进行钻削试验,记录钻削过程中的轴向力,观测孔的出口质量。试验和仿真结果吻合性良好,结合仿真和试验的结果,确定旋刨刀的后角为10°。

Abstract:In order to improve the drilling quality of carbon fiber composite material(CFRP),the geometric structure of CFRP rotary planer cutter is designed.With 15° rotary planer cutter′s rake angle,the sub module is analyzed by using finite element analysis software ABAQUS,a threedimensional model of the CFRP rotary planning drilling is established and the simulation and analysis in the process of axial force and drilling export quality are analyzed.Under the same conditions,the drilling experiments are carried out to record the axial force in drilling process and observe the drilling export quality.It is found that the results of experiment and simulation are in good agreement.According to the results of simulation and experiment,the rotary planer cutter′s back angle is determined to be 10°.
