CNC kontrollü dairesel interpolasyon hareketlerindeki yuvarlaklık hatasının en küçük karaler metodu ile değerlendirilmesi

Bu çalışmada, ISO 230-4 "NC Tezgahlar için Dairesel Testler" isimli standarda dayalı yuvarlaklık (dairesellik) hatasının bulunmasına yönelik bir algoritma önerilmektedir. Daireyi, 2 boyutlu düzlemde gerçekleştirilen dairesel interpolasyon hareketine ait konum verisine uydurmak amacıyla en küçük kareler metoduna dayalı Gauss-Nevvton nümerik çözümleme yöntemi kullanılmıştır. Çok amaçlı ölçüm algoritması Matlab 6.5 yazılımı kullanılarak geliştirilmiş olup, CMM (Coordinate Measuring Machine), lazerli küresel çubuk, ızgara enkoderi gibi cihazlarda rahatlıkla kullanılabilmektedir.

The assessment of circularity error in CNC controlled circular interpolation movement by least squares method

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.
