摘要
磨削加工作为试样制备的最后一道工艺,对试样的表面质量影响很大。砂带抛光工艺相对于传统砂轮磨削来说,有效率高,质量好等优点,适于试样加工。通过一系列的正交实验和单因素实验,针对A-100材料,探索了抛光速度,进给速度,抛光深度和砂带粒度对试样表面完整性的影响。实验结果表明通过优化上述参数,减少试样表面残余应力,降低表面粗糙度,从而提高试样的表面质量。
As the last process of specimen preparation, grinding has a great effect on quality of specimen surface. Compared with grinding, abrasive belt polishing is more efficient and has a better quality, and it is suitable for specimen preparation. In order to research the effect of polishing velocity, feeding speed, polishing depth and grit size on surface integrity of specimens, which are made of A - 100 steel, a series of orthogonal tests and single factor tests are carried out. The surface roughness and residual stresses can be reduced by optimizing these parameters based on the research, and the surface quality of specimen can be improved.
