摘　　要：深孔直线度的准确检测是深孔加工行业亟待解决的难题。为解决该难题,设计了一套深孔直线度检测系统,对不同深孔截面边界上多个点的坐标利用阻尼牛顿法求解深孔截面圆心,得出被测工件的实际轴线,最后通过"两端点连线法"计算出深孔直线度。为深孔直线度检测提供了一套检测系统与测算方案,该系统有利于提高测量精度与效率+;是深孔直线度检测的一个创新。Accurate detection of deep hole straightness is a complex problem that should be solved the sooner the better in deep hole processing industry. To solve the problem, a set of deep hole straightness inspection system was designed ; the Damp Newton Method was used to solve the centers of the circles of the deep hole sections with the t results of the test system. Then , the actual axis of the measured workpiece was obtained; finally, the deep hole straightness was calculated by ＂two end point method＂. This inspection system and the measuring scheme are beneficial to improve measurement precision and efficiency, which provides a research reference for deep hole straightness inspection.
