Abstract：

Forming parts of metallic wire are widely used, but its machining accuracy is difficult to be controlled because of the comprehensive influence of geometric parameters, material properties and other factors. For this phenomenon, an error correction method based on iterative mechanism was proposed by changing the radius of the planar spiral wire parts. Firstly, the geometric relationship among the wire forming radius, cumulative bending angle and wire feed length was derived by analyzing the geometric characteristics of the object to be processed. And then, the formula between the feed axis and the push bending axis was constructed. Finally, the radius error correction model of planar spiral wire was established and applied to the forming process of wire parts with equal radius. The machining result shows that the proposed method could improve the accuracy of wire processing effectively.
