AI Technical Summary

Technical Problem

In existing technologies, the small spacing between boundary holes during short slot hole position detection makes it difficult for AOI equipment to identify the hole position, thus hindering efficient and accurate hole position detection.

Method used

By employing a boundary hole group consisting of a first boundary hole that is a blind hole and a second boundary hole that is a through hole, the deviation data between the actual coordinates and theoretical coordinates of the second boundary hole is scanned using AOI equipment. The deviation data is then analyzed in conjunction with the Cpk detection map to improve detection accuracy.

Benefits of technology

This improved the accuracy of AOI equipment in detecting the deviation between the actual and theoretical coordinates of the short slot, enhanced the precision and reliability of short slot hole position detection, and reduced the difficulty of detection.

Abstract

The invention relates to a short groove hole position precision detection method, a short groove machining method and a storage medium, and belongs to the technical field of precision machining detection. The short slot hole position precision detection method comprises the following steps that S1, a boundary hole set of a short slot is machined in a plate 100, the boundary hole set comprises a first boundary hole and a second boundary hole, the first boundary hole is a blind hole, and the second boundary hole is a through hole; s2, scanning a second boundary hole in the plate 100 by using the AOI equipment to obtain deviation data of an actual coordinate and a theoretical coordinate of the second boundary hole; and S3, analyzing the deviation data of the second boundary hole, and judging the offset of the short slot according to the offset of the second boundary hole. According to the short slot hole position precision detection method, the short slot processing method and the storage medium provided by the invention, the problem that AOI (Automatic Optic Inspection) equipment cannot identify due to the fact that the short slot boundary hole pitch is too small in the prior art is at least solved.
