摘要
为探索较低成本高质量的玄武岩纤维树脂混凝土(BFPC)切削工艺方法,综合应用有限元模拟仿真分析和物理试验研究方法研究硬质合金刀具切削BFPC材料过程中切削力和加工表面质量随着切削用量的变化规律。结果表明,当刀具几何参数一定时,切削力的波动和加工表面粗糙度均首先随切削速度和背吃刀量的增大而减小,当减小到一定值后,又随着切削速度和背吃刀量的增大而增加。即存在一组最优的切削用量,此时切削速度为v=0.5 m/s、背吃刀量为a_p=0.10 mm。
In order to explore the low cost and high quality cutting technology for basalt fiber reinforced polymer concrete （BFPC）. The change law of cutting force fluctuate and the machining surface quality with cutting parameters are studied by simulation and experi- mental.It is shown that cutting force fluctuate and the machining surface roughness decrease with the Increase of curing speed and depth at first and then increase with it when geometric parameters of cutting tool are certain.There exists a set of optimal cutting parameters that is v=0.5 m/s and a_p=0.10 mm.
