4.1
Acceptance of the principle of
Acceptance method should only be used to receive the work within the specified limits of size within.
4.2 Acceptance based approach
Since the measuring instruments and measurement systems have inherent errors, it can not be measured by any measurement true value. In addition, most common measuring instruments
Usually only used to measure the size, shape measurement errors may not exist on the workpiece. Therefore, the size required to follow an inclusive element of the workpiece
It should also improve the inspection and measuring shape errors (such as roundness, straightness, etc.), and the results of measurements of the shape and size of the integrated error
Up to determine whether all parts of the surface exceeds the maximum entity boundary.
In the workshop the actual case, the shape error of the workpiece often depends on the precision equipment and processing technology and equipment. Workpiece qualified or not, just press […]
