高温合金GH901车削加工刀具磨损实验测试及理论建模
Experimental Testing and Theoretical Modeling of Tool Wear in Turning GH901 Superalloy
摘要
Abstract
The turning experiments of Superalloy GH901 were carried out with three different types of cutting tools A,B and C at 40m/min and 60m/min.By observing the tool flank wear state,the life curves of tool are established and the tool types are optimized according to the tool wear and life curves.Finally,the prediction model for tool wearis established.The maximum root mean square error and mean absolute error of the experimental and the prediction results are 0.04349 and 0.03943 mm,respectively,the small error proves the effectiveness of the prediction model.The comprehensive cutting performance from high to low is toolA,tool B and tool C.The chip type is dominated by long annular spiral chips,and the tool life is significantly reduced with the higher cutting speed.关键词
