Background

The position degree of the round hole refers to the projection distance between the hole and the reference and between the holes. In the machining industry, the position of the circular hole is generally measured by using measuring instruments such as a ruler, a caliper and a projector, but for some products with high precision requirements, only the high-precision instruments such as the projector can be used for measurement. The projector on the market generally has a short measuring range, and for a measuring object with a large size, a small tolerance and high precision, the measuring range of the projector is insufficient, so that an effective measuring method for the measuring object is lacked.

In the manufacturing process of the lead frame, the accumulated tolerance is often monitored by measuring the distance of the positioning holes, and for a large accumulated tolerance, because a precise measuring instrument with a sufficient range is not available, the accumulated tolerance can only be calculated by measuring a small accumulated tolerance, and accurate data cannot be obtained.

An effective solution to the problems in the related art has not been proposed yet.
