摘要
首先从理论上分析了影响硫化氢应力腐蚀试样表面质量的各种磨削参数,然后针对这些磨削参数设计出正交试验,进行研究和分析各参数的影响。试验结果表明,磨削过程中,磨削深度对试样表面残余应力影响最大,砂轮颗粒度对试样的表面粗糙度影响最大。试验结果证明,在砂轮线速度vs=30m/s的情况下,使用砂轮颗粒度为180#的砂轮,在工件转速vw=460r/min、轴向进给速度f=0.25mm/s、磨削深度ap=0.010mm的磨削条件下进行切削时表面质量最为优化。
The influence of grinding parameters on surface quality of in specimen H2 S SCC test are stuaief theoretically at first. Then the orthogonal experiment is designed to research and analyze the influence of each parameter. It is shown that surface residual stress is mainly affected by the depth of grinding ap and surface roughness is mainly affected by grind wheel grain size. It is proved that optimial grinded surface quality is obtained in case of vx = 30m/s, vw = 460r/min, f=0.25mm/s, ap =0. 010mm and D = 180#.
