Variations in sampling points are a significant factor affecting the measurements of a Coordinate Measuring Machine (CMM).

During measurement, if the CMM takes a different number of points, or even if the number of points is the same but their positions differ, the results calculated by the measuring instrument can vary considerably. Of course, measurement accuracy is also greatly influenced by errors caused by the machine's placement and the usage environment. A clean, dust-free setting, free from noise and vibration, with stable temperature and humidity, allows the measuring instrument to perform optimally.

Other issues, such as errors caused by programming problems, should be addressed by contacting OGP training personnel. For accuracy errors resulting from hardware failures, please get in touch with an OGP service engineer.

To achieve optimal measurement accuracy, it is recommended to calibrate the instrument every six months and conduct professional inspection and maintenance.
