Abstract：

A way of automatically generating NC code for the push bending of spiral wire was introduced, and the equal-pitch conoid helical-coil spring whose curve model is relatively complex was emphatically discussed. Through extracting wire parameters of geometric modeling, and combining with the structure size and movement of push bending dies, the mathematical model of the push bending of spiral wire was made, and the linkage relationship among the feed axis, the push bending axis and the rotational axis was derived. Finally NC code was generated by equidistant linear approximation and the processing production was done. The experiment result shows that the programming efficiency of this method is high, the modification is easy, and the parts produced can meet the requirement of accuracy.
