| Abstract: | This paper deals with a mathematical model in which the control of the electrical discharge wire-cutting machine through feeding and interpolating in eight directions is implemented based on the principle of object tracking with interpolation.A comparative study between this method and the point-by-point comparison with interpolation proves that it has some traits: simple formula,fast velocity,short program and stabilization of feeding and interpolating velocity.Furthermore,the block diagram and the software design in the interpolation method by object tracking are presented. |
