1. Measurement of the included angle of Wholesale JIC Male Thread products: The threaded angle is also called the tooth angle. The measurement of the thread angle can be realized by measuring the flank angle, which is the angle between the thread flank and the vertical plane of the thread axis. The approximate profile of the thread teeth is sampled on the straight line segments on both sides of the thread, and the least squares fitting of the sampling points is carried out.

2. Measurement of the thread pitch of Wholesale JIC Male Thread products: The thread pitch refers to the distance between a certain point on the thread and the corresponding point on the adjacent thread teeth. The measurement must be parallel to the thread axis.
3. Measurement of the pitch diameter of Wholesale JIC Male Thread products: The thread pitch diameter is the distance from the pitch line perpendicular to the axis, and the pitch line is an imaginary line.
Using machine vision technology, an automatic detection system for thread parameter measurement is designed, and parameters such as thread angle, pitch and pitch diameter of standard thread samples are measured. The measurement results show that the thread parameters are within the specified error range. Due to the high efficiency and reliability of visual inspection, after further investigation, it is considered that it can be used in production practice.
On a section through the axis of Wholesale JIC Male Thread products, the profile shape of the thread is called the profile. The angle between two adjacent tooth flanks is called the tooth profile angle. The tooth profile of the commonly used common thread is triangular, and the profile angle is 60°.
