摘要
为研究切削参数对GFRP(玻璃纤维复合材料)螺旋铣孔铣削力的影响,建立了GFRP螺旋铣孔的仿真模型,选择不同切削参数进行切削仿真。为验证所建立仿真模型的合理准确性,进行GFRP螺旋铣孔正交试验,选择与加工仿真相同的切削参数,通过仿真与试验结果的对比分析,验证了仿真模型的合理性。基于此仿真模型,通过GFRP螺旋铣孔的仿真试验得到切削参数对铣削力的影响规律。研究结果表明:对铣削力的影响程度由大到小依次为轴向进给螺距u、刀具中心的公转速度ω和切削速度v c;随着切削速度增大,铣削力先减小后增大,但变化趋势较小;随着刀具中心的公转速度增大,铣削力逐渐增大;随着轴向进给螺距增大,铣削力逐渐增大。
In order to study the influence of cutting parameters on the milling force of GFRP(glass fiber composite)spiral milling holes,a simulation model of GFRP spiral milling holes is established.Different cutting parameters are selected for machining simulation,and different milling forces are obtained.In order to verify the reasonable accuracy of the established simulation model,an orthogonal GFRP spiral milling experiment is conducted.The same cutting parameters as the machining simulation are selected,and multiple sets of different milling forces are obtained.The rationality of the simulation model is verified through comparative analysis of simulation and experimental results.Based on this simulation model,the effect of cutting parameters on milling forces is obtained through GFRP spiral hole milling simulation experiments.The results show that the order of influence on the milling force from the largest to the smallest is the axial pitch feed u,the revolution speed of the tool centerωand cutting speed v c.As the cutting speed increases,the milling force first decreases and then increases,but the trend of change is small.With the rotational speed of the tool center increases,the grinding force gradually increases.As the axial feed pitch increases,milling force gradually increases.
