摘要

为了优化超精密飞刀切削加工表面的粗糙度

对超精密飞刀切削加工主要参数的变化进行了实验研究。根据超精密飞刀切削加工机床加工原理

分析了影响加工工件表面质量的因素。使用控制变量法对不同的切削参数进行了实验和理论分析的对比

以寻找最优加工参数组合。实验显示:加工后的工件表面粗糙度和表面刀纹对低主轴转速、较高的进给速度比较敏感

而对切削深度较为不敏感;同时转速400 r/min

进给速度60

切削深度6

m时

加工后的工件表面粗糙度均优于7.5 nm

并且基本不存在加工刀纹。实验结果表明

合理选择飞切加工切削参数可以保证加工表面粗糙度及效率。

Abstract

To optimize the surface roughness in ultra-precision fly cutting machining

a number of experiments were conducted to analysis on the changes of main factors affecting the surface roughness. On the basis of the processing principle of ultra-precision fly cutting machine

the main factors affecting surface roughness were analyzed theoretically. To obtain an optimized parameter combination

the experimental results were compared with the theoretical results of different cutting parameters by using the control variable method. Experimental results indicate that the surface roughness and blade ripples are sensitive to low spindle speed and high feed rate

but is not sensitive to cutting depth. Meanwhile

under the cutting conditions in spindle speed of 400 r/min

feed rate of 60

m/s

cutting depth within 6

the surface roughness is better than 7.5 nm

and shows a smooth surface. It concludes that choosing reasonable processing parameters allows to optimize the surface roughness and improve the machining efficiency.
