摘要
简述超声衍射时差(TOFD)法的基本原理,提出反求工程在TOFD法无损检测中进行三维计算机辅助设计(CAD)建模的方法,并给出缺陷计算公式及CAD建模效果模拟图。
The basic principle of ultrasonic time-of flight diffraction（TOFD） was briefly described. Reverse engineering was applied in CAD modeling for ultrasonic TOFD testing, and the calculating formulae for defect and the simulated drawing of CAD modeling result.
