[0002] A horizontal arm coordinate measuring machine is a precision measuring device that determines the geometry, size, and position of an object by measuring the three-dimensional coordinates of points on the surface of the object in space. Its basic principle is based on the Cartesian coordinate system, in which points in space are located by three mutually perpendicular coordinate axes.

[0003] Measuring instruments generally include a probe and a stylus. The probe is the sensor that detects contact with the surface of the object being measured and converts the contact signal into an electrical signal. The stylus is mounted on the probe, and its shape and length can be selected according to the specific situation of the object being measured. The measuring instrument sends the electrical signal generated during measurement to an external computer for processing through wires.
