This is yet another crucial phrase used in CNC machining. This phrase also describes how reliable a machine tool is. In essence, precision is a measure that describes a measurement system’s capacity to consistently return the same measure. You might refer to it as the measurement system’s repeatability. Therefore, you must ensure strong repeatability of the system if you want to obtain accurate information that you can utilize for further calculations. In addition, it is crucial that a measurement system be both accurate and exact.
