Research on The Wire Drawing Die Pass Parameter Calculation Based on The Least Square Algorithm
Drawing Dies meter A / D acquisition module will be collected from the mold hole contour data to draw a curve in Matlab.According to the mold pore structure characteristics of the curve,the initial cut-off point of each part of contour is determined and iteratived optimization to find the best cut-off point,use the least squares method for fitting piecewise linear and fitting optimization to find the function of the various parts of the curve function,fmally calculate the pass parameters of drawing mode.Parameters obtained compare with the standard mold,both of errors are relatively small that prove the correcmess of the algorithm.Also a complete algorithm flow of pass parameters is designed,it can fast and accurately measure the wire drawing die hole parameters.
