Abstract

The invention provides a method for processing the three-coordinate data of threaded holes, which includes the following steps: recording the product number and detection information of the measured threaded holes when measuring the three-coordinates data of the threaded holes; taking the top surface of the threaded hole as the reference plane , select the starting point along the crest of the threaded hole, and get the coordinates of the crest center point according to the pitch; select the starting point along the root of the threaded hole, and get the coordinates of the root center point according to the pitch; Calculate the average value with the obtained root center point coordinates to obtain the center point coordinates, and the projection point of the center point coordinates on the reference plane is the center point of the threaded hole top surface. The processing method records the product number and detection information of the measured threaded hole when measuring the three-coordinate data of the threaded hole, so as to facilitate the traceability of the threaded hole product when a problem occurs; The coordinates of the tooth root are recorded, and the accurate coordinates of the center point of the top surface of the threaded hole can be obtained.
