摘要

建立了基于数控装备的液流悬浮超光滑加工系统，研制了可控制加工压力的柔顺加工装置。应用流体动压理论分析了液流悬浮超光滑加工过程中的流体动压力分布规律，研究了工具转速和加工间隙对流体动压力的影响规律，并通过实验得到了加工间隙和流体动压力对加工效果的影响规律。结果表明，随着工具转速的提高，流体动压力逐步增大，在工具转速为6000 r/min 左右时流体动压力达到最大值，然后又逐渐减小。随着加工间隙的增大，流体动压力逐步降低，并最终趋于稳定。加工间隙在5-40 m时，加工效果比较明显。在工具转速为6000 r/min 左右、加工间隙在10 m附近时，流体动压力增强为5N左右，加工效果最佳。

Abstract

A hydrodynamic suspension machining system based on NC machine tool is constructed. And a compliant machining apparatus was developed. Fluid pressure distribution in the machining clearance was analyzed by hydrodynamics. The experiments to find influence on fluid pressure of machining clearance and motor rotate speed. Meanwhile

by conducting experiments

the correlation between the surface roughness of machining clearance and motor rotate speed was revealed. Experimental results indicate that with the increasing of motor rotate speed and decreasing of machining clearance

fluid pressure increased gradually and then decrease relatively after it reached certain value. When the motor rotate speed is 6000 r/min

the hydrodynamic pressure obtained max value. It was shown that when the machining clearance is between 5 and 40 m

the machining effect is distinct. And in the condition of maintaining clearance 10 m and hydrodynamic pressure maintained to be 5N

the machining effect is optimal.
