摘　　要：针对不锈钢材料切削加工的难题,采用回归正交表设计试验方案。采用回归方法对试验数据进行分析,建立表面粗糙度模型。利用自编程序迅速、准确地完成试验数据的选取、处理,并进行结果分析。结果表明:切削速度、进给量、车刀刀尖半径对表面粗糙度的影响明显,而切削深度对表面粗糙度的影响不明显;增大切削速度、车刀刀尖半径可降低表面粗糙度,增大进给量会使零件表面粗糙度变大。试验结果对不锈钢的加工有重要的参考价值。Aimed at the difficult problem of stainless steel material cutting machining,the regression orthogonal table was used to design the experiment scheme.The experiment data were analyzed by using the regression method,and the surface roughness model was established.The selection and processing of the experiment data were completed quickly and accurately by using the self-programmed program,and the results were analyzed.The results show that the cutting speed,feed rate and turning tool tip radius have obvious influence on surface roughness,while cutting depth has no obvious influence on surface roughness;with the increase of cutting speed and turning tool tip radius,the surface roughness decreases,while with the increase of feed rate,the surface roughness increases.The experiment results have some reference value for the processing of stainless steel.
