When measuring the misalignment amount b between the mating surfaces, the difference in the thicknesses of the two plates should not be taken into account. What does that mean?

What does GB150.4 6.5.3 mean when it states that the difference in thickness between the two plates should not be taken into account when measuring the misalignment amount b? Shouldn’t the misalignment amount be determined simply according to its definition? What does it have to do with the difference in thickness of the two plates? Why emphasize it?

Therefore, the value of b is 1.0 – it must be set this way. Otherwise, if your inspector decides that the product is unqualified based on an edge deviation of 3.0, it’s clearly a wrong judgment. It should be determined according to the thickness, by checking Table 1 to see if it meets the requirements
The difference in thickness and the amount of misalignment are two different things.
