In automobile manufacturing, in order to ensure the high-speed production and quality assurance of each component, batch testing is carried out with the help of high-precision measuring instruments. The CMM is the most widely used measuring instrument in the automotive industry, which can meet most of the measurement needs with high precision and high efficiency.

The work plane was not noticed. Especially when the programming hand picks the coordinates for the initial construction, if the working plane is not switched to the straight line used to build the coordinate system, it is likely to cause the rotation direction to deviate greatly or be invalid, and almost all such programs cannot run or collide.
