In this study, an algorithm is proposed in order to find circularity error based on ISO 230-4 called “Circular tests for numerical controlled machine tools”. For fitting circle to position data of circular interpolation movement in 2 dimensional plane, Gauss-Newton numerical solution method, based on least squares method, is used. Multi functional measuring algorithm is developed by using Matlab 6.5 software and it can be used easily in the devices such as CMM (Coordinate Measuring Machine), laser ball bar and cross grid encoder.
