众所周知,复杂形状零件的自动测量有各种不同的方法,但用得最普遍的方法是基于被测轮廓与标准样件相互比较。如果按轮廓的标准给定另件上的公差,则在接触测量的情况下,按程序或者自动调整的方法实现测量头相应的定向。接触方法的缺点是有测量力和动态误差。下面叙述非接触方法,此法可以获得很高的测量精度和测量效率。根据标准样件测量时,通过在间隙里局部的电磁场的扫描和信号的峰值测量来实现。电磁场由间隙转换器与开缝涡
As we all know, there are different methods for automatic measurement of complex shape parts, but the most common method is to compare the measured contour with the standard sample. If the tolerances on the component are given according to the contour standard, the corresponding orientation of the measuring head is achieved by program or by automatic adjustment in the case of contact measurement. The disadvantage of the contact method is the measurement of force and dynamic error. The following describes the non-contact method, this method can obtain high measurement accuracy and measurement efficiency. According to the standard sample measurement, through the gap in the local electromagnetic field scanning and signal peak measurement to achieve. Electromagnetic field by the gap converter and slit vortex
