摘要
应用均匀试验设计方法,在较宽切削速度范围内,对1Cr18Ni9Ti奥氏体不锈钢进行平面铣削试验研究。通过指数回归和二次多项式回归分别建立了切削力和表面粗糙度经验公式,采用分层多目标优化方法获得了M20硬质合金刀具切削1Cr18Ni9Ti奥氏体不锈钢时的优化切削参数。试验结果表明,本文采用的试验设计方案和建立的切削力和表面粗糙度经验公式是合理可行的。
The equal design method was applied in face milling 1Cr18Ni9Ti austenitic stainless steel in case of large range of cutting speed. The cutting force and surface roughness of workpiece were measured and the experience formula were setup by use of exponential regression and quadric polynomial regression respectively. Based on the above mentioned formula and hierarchical multiple objects optimization approach, the optimal parameters in face milling 1Cr18Ni9Ti austenitic stainless with M20 tungsten carbide cutting tools were presented. The verified test with the optimal parameters proved the rationality and feasibility of the expe-rience formula.
