1. The site space of the installation site should be large enough for the installation, normal operation and maintenance process to proceed smoothly. It is very necessary to accurately plan the room of the CMM in advance, so that the user can easily transport it to the work platform. Pneumatic control unit, control sys···

In addition to the four geometric errors of positioning error, straightness error, angular motion error, and perpendicularity error, the CMM also has four geometric errors due to force deformation, thermal deformation, measurement system, probe system, control system, data recording and processing. Errors generated by ···
