{1. Cruinneas suiteála
Refers to the moving parts such as NC machine tool table positioning accuracy in determining the end up to the accuracy of the actual location of, so moving the error between actual and ideal locations called position error. Includes servo system, positioning error checking systems, feed systems and other errors, including moving parts geometrical error of the Rails. Will directly affect the position of Machining accuracy of location earráid .
{2. Cruinneas suiteála in -atrialltachta
Repeat positioning accuracy means on the same CNC machine tool, applying the same program code processing a number of parts, the result of continuous consistency. Repeat positioning accuracy of servo system characteristics, feeding system of clearance and influence of rigidity and friction characteristics and other factors. Under normal circumstances, repeated positioning accuracy is accidental errors of the normal distribution, it affects the consistency of a number of parts, is táscairí feidhmíochta an -tábhachtach .
