The CMM is composed of a measuring machine host, a control system, a probe base system, and a computer. The cuboid control cabinet that we open every time we turn on is the control system of the CMM. The following describes the main functions of the CMM control system:

1. Control and drive the movement of the CMM, and control the three-axis synchronization, speed and acceleration, so that each axis of the CMM can move accurately and stably;

2. After the probe is triggered, the transmitted trigger signal is collected and the grating reading is processed;

3. According to the compensation document, 21 error compensations are made for the CMM to ensure the measurement accuracy;

4. Collect temperature data and compensate the error caused by temperature deviation of the CMM;

5. Detect the working state of the CMM, and take protective measures in case of any abnormality.

It can be said that the control system is the control center of the CMM and the communication medium between the CMM and the computer software.
