Hey guys I want to know what is A to B conversion and how it is done ? Thanks in advance.
There are three surfaces A,B and C surface .. all of them have its own tolerances zone.. So A surface is a surface having tolerance or deviation of surface by 0.01mm .. suppose u have a part .. So the outer surface of d part is called as the A surface and the inner surface which defibes thickness is called as B surface.. andthe joining of A and B surface is said to be C surface.
