A coordinate measuring machine is a high-precision 3D measuring device that establishes a Cartesian coordinate system and uses a probe system to obtain coordinate data of surface points on the workpiece, achieving high-precision measurement of geometric dimensions, shapes, and positions.
working principle
Coordinate system establishment: The three coordinate measuring machine consists of three mutually perpendicular axes of motion (X, Y, Z) forming a Cartesian coordinate system, and the motion trajectory of the measuring head is represented by the center point of the measuring sphere.
Data collection: The measuring head comes into contact with the surface of the workpiece (contact measurement) or obtains data through optical, laser, or other methods (non-contact measurement), and the detection system records the position of the center point of the measuring ball in the coordinate system in real time.
Data processing: The collected coordinate data is processed by computer software to fit measurement elements such as circles, spheres, and cylinders, and to calculate geometric dimensions, shapes, and positional tolerances.
Advantages:
High precision measurement: Using precision mechanical systems and excellent measurement techniques, the measurement accuracy can reach the micrometer level, meeting the requirements of high-precision manufacturing.
