Curve Synthetic Interpolation Theory and Application in LWEDM

Zhao Qingzhi Liu Zhengxun Gu An Wang Wei Gao Changshui Nanjing University of Aeronautics and Astronautics,Nanjing,210016  
A curve synthetic interpolation theory with compensation of wire radius and spark gaps had been expounded theoretically and practically. With the theory,the offset distances of any straight lines and quadratic curves could be interpolated indirectly with the help of outlines and wire circle informations,it was unnecessary to calculate offset curves. This method avoided effectively traditional calculating errors of offset curves, the control precision of LWEDM has been increased, problems dealing with the theory has been solved in this paper,and the theory has been used in LWEDM.
