This paper presents a method and analysis for determining the geometric accuracy of CNC milling machines. The method measures the accuracy of five basic geometric values: straightness, circularity, size, angularity, and position. Tolerance prediction models are found using statistical analysis. The tolerance prediction models are used to find more complex tolerance values. The results of the paper will allow manufactures to measure the actual tolerance capabilities of their machines and no longer rely on guess work. The method and analysis can also be applied to other machining processes.
