4 .Pre-Treatment of Workpiece
4.1 Workpiece Requirements
4.1.1 Surface Roughness requirements
Surface roughness is an important requirement for the surface of the test
piece, it should be smooth and no oil, or will cause measurement errors.
The surface roughness of the test piece should not exceed the value in the
bellowing table:
