摘要
基于红外-热导联合法,提出一种通过检测高速精铣产生的切屑的氧、氮、氢元素含量来间接检测材料新表层的氧、氮、氢元素含量的方法,并利用均匀设计法设计了高速精密铣削试验方案。用最优回归子集法建立了高温合金表层氧、氮、氢元素含量的多元二次回归模型,回归效果显著。
A detection method for oxygen, nitrogen and hydrogen content of superalloy＇s new surface during high-speed milling was proposed through the detection of oxygen, nitrogen and hydrogen content of chips indirectly based on the infrared-thermal conductivity method. And a high-speed fine milling experiment program was projected by uniform design method. The quadratic regression model of superalloy was established using best regression subset method and the regression effect was good.
