Abstract A detection method for oxygen, nitrogen and hydrogen content of superalloys 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.
