目的:获得一个不规则最大实体实效状态MMVC(美标称之为MMB)的边界(不允许超越)作为定位边界,保证装配(以基准A定位) 学名:基准偏移 (美标称为Datum Shift, 欧标称为….,徐老师也不知道,欧标没写!居然没写!) 好处:通过基准定位调整来帮助装配,达到间接放宽公差的目的,方便做检具验证,"一般"不用于测量计算 学员...
Among all the datum features, we give the highest preference to those that mate with other parts in the assembly. We can mention more than one datum in our feature control frame. As per the sequence of the DRFs in the feature control frame, the parts are mated to the DRFs in decreasing...

NOVACAM systems are modular and fiber based, meaning that the scanning optical probes are connected to the system interferometer with an optical fiber that can be several meters long. Thanks to the unique combination ofLow-coherence Interferometry technology and fiber-based design, the systems offer ...
