| Abstract: | In this paper, we analyse the features of bicircular arc interpolation algorithm which isoften used in numerical control manufacturing. On this basis ,we present an algorithm of bi-circular arc interpolation of vector representation,which transforms triangle calculation in lo-cal coordinate into linear calculation in global coordinate. Thus, the complexity of programand calculation is decreased,efficiency and reliability is raised. |
