摘　　要：针对精细等离子切割内孔时的引入引出点缺陷问题,以引入引出参数设置为切入点,设计正交试验并进行对比分析。确定引入圆弧半径为9mm、引入角度为70°、引出圆弧半径为5mm、引出角度为70°、间隙值为2mm是优化参数组合,结果显示其可以明显改善引入引出点切割质量,将凹坑深度控制在<0.5mm,解决了精细等离子切割引入引出点缺陷问题。Aimed at the cut-in defects of inner holes from precision plasma, orthogonal experiment about cut-in parameter was designed following with comprehensive analysis. The optimized cut-in parameters with cut-in radius of 9 mm, cut-in angle of 70°, cut-off radius of 5 mm, cut-off angle of 70° and gap distance of 2 mm were obtained, which brings significant improvement on cutting quality. The defects depths can be controlled under 0.5 mm, along with the solution of cut-in de- fects from precision plasma.
