The company has purchased a new measuring instrument - a 3D coordinate measuring instrument. The measurement principle is to use a probe to collide with the edge of the workpiece, obtain the coordinate value of that position, and then subtract the radius of the measuring head to obtain the actual coordinate value of the workpiece. Generally, optical rulers are installed on the three axes of measuring instruments. When the measuring head contacts the workpiece, a signal is sent to capture the target coordinate value. After being processed by the measuring software, the desired coordinate value or size can be calculated. Therefore, as long as the measurement position is taken, the measurement data can be obtained. This can accurately measure various workpiece sizes, angles, shapes, and positions, as well as various parameters of threaded parts
