[0030] Specifically, the positioning accuracy of the mounting hole refers to the range of position variation allowed for the axis of the mounting hole, that is, the range of position variation allowed for the actual position of the axis of the mounting hole relative to the reference. It is an indicator that limits the amount of variation in the actual position of the measured element relative to the ideal position.

[0031] In addition, the matching surface on the body-in-white refers to the surface used to match with other parts when connected, such as the matching surface on the headlight bracket 8 is used to match with the headlight connection structure. The surface profile of the matching surface refers to the change of the actual profile of the measured surface relative to the ideal profile, which is the main indicator used to describe the shape accuracy or size accuracy of the curved surface.
