Automatic Evaluation Algorithm for Hole Cylindrical Feature in CNC Machine Application

This paper proposed an algorithm to evaluate hole properties automatically. The proposed algorithm analyzes probe path, reference data, measurement data, and tolerance data to evaluate hole properties based on tolerance data ISO 2768. The proposed algorithms was verified experimentally by implementing to holes evaluation software which is developed by phyton programming. A 3D product model with two different hole was designed to validate the proposed algorithm. according to the experiment result, proposed algorithm can evaluate hole properties properly with quality control sheet format as output. Then, the proposed algorithm experiment is compared with manual evaluation.
