硬质合金铣刀加工塑料尼龙时工件表面质量的影响与优化

结合FANUCoi系统VM850加工中心对塑料尼龙材料进行平面加工试验,观察尼龙在特定加工参数条件下的切屑运动方向和形态。利用Daisy8106型三坐标测量机对加工成型的尼龙表面进行平滑度、平行度测量,分析硬质合金铣刀在不同的每齿进给量与切削深度下塑料尼龙工件的铣削表面质量,得出最佳的每齿进给量fz=0.075mm/r、切削深度Δd=6mm。结果表明,在铣削尼龙的过程中,合理采用每齿进给量、铣削深度、主轴转速等工艺参数,能使产品的平滑度及平行度达到加工的高精度要求,实现尼龙的高速和高质量的铣削。

Effect and Optimization to Workpiece Surface When Using Carbide Cutter Machining Plastic Nylon Material

Observing the direction of movement and shape of the chip when doing planarization processing test of the plastic nylon material under certain conditions of processing parameters by VM850 machining center of FANUCoi system.Obtaining the best results as these:each tooth feed fz =0.075ram/r,cutting depth Ad =6mm,through measuring the flatness and parallelism of the surface of the plastic nylon that have been processed forming by a CMM of Daisy8106 type and analyzing surface quality of the plastic nylon piece milling in condition of different feed rate of each tooth and different cutting depth by the use of carbide cutter.The results show that,to reach the high demand of smoothness and parallelism of the product and to achieve high-speed and high-quality cutting performance,it is necessary to rational use the process parameters such as each tooth feed,cutting depth,spindle speed and so on.
