Knowledge of machining technology is critical for the selection of the right equipment for the job. That said, there appears to be a lot of misunderstanding of three common machining terms: precision repeatability, and accuracy. This misunderstanding of terms causes people to use them incorrectly, and when the customer and the CNC machining company are not on the same page, miscommunication can ensue. Knowing the proper definition of these terms permits all parties involved to have a common frame of reference.
Precision
Precision is defined as the number of significant digits to which a value has been measured. To a CNC user, precision is basically the smallest movement a machine can make. For instance, a CNC machine that moves 0.0005 inches is more precise than one that moves 0.005 inches. While CNC in general offers high precision, this is usually related to the cost of the machine.
