中文摘要：
为了实现某弹体在车削加工过程中弹体厚度的自动测量,采用喷水式的非接触超声检测方法,利用弹体和刀架的匀速旋转和移动,在工控机的控制下实现弹体的全面检测。通过动态模板匹配的超声回波处理方法计算出弹体各检测位置的厚度值。检测结果表明,该检测方法的检测精度可达到0.1 mm。
英文摘要：
The non-contact ultrasonic method is used to measure the missile body＇s thickness in turning process. The measurement of the whole missile body is controlled by industrial personal computer,which utilizes the uniform rotating speed of the projectile body and uniform movement speed of the tool-holder. The thickness of the missile body is calculated by using dynamic template matching to process the ultrasonic echo signal. The result shows that the measuring accuracy of missile body＇s thickness can reach 0.1 mm.
