Study on Influence of Milling Parameters on Mechanical Properties of Carbon Fiber Reinforced Plastics
-
摘要: 为研究铣削参数对复合材料力学性能的影响, 开展了以主轴转速与进给量2个变量为试验因素的全因素铣削加工试验, 并统计分析了不同加工参数下复合材料试样的拉伸性能及压缩性能。试验结果表明: 复合材料的拉伸性能和铣削加工参数无关, 而压缩性能随着主轴转速的提高而降低, 与进给量无关。同时, 不同加工条件下的拉伸及压缩测试断口形貌表明, 过高的主轴转速会造成加工区域基体的热损伤, 分析认为这是造成材料压缩性能下降的原因。Abstract: For the research of the influence of the milling parameters on the mechanical performance of the components, a full factors experiment was carried out with two variables of spindle speed and feed rate per rotation, and statistics the tensile properties and compressive properties. The results of the experiments show that the tensile property of the composite does not relate to the milling parameters, while the compression property will decrease with the increasing of spindle speed, and does not relate to the feed rate. Meanwhile, the fracture morphology of the tensile tests and compressive tests under different cutting conditions shows that the excessive spindle speed will cause the matrix's thermal damage in the machining area, and the analysis suggests that the thermal damage causes the decreasing of the compressive properties.
