Simulating and Design of the Irregular Cutting Edge with BP Neural Network

Aiming at the design of irregular cutting edge of cutting tool, the method of simulating the cutting edge with the aid of BP neural network was presented. Due to the profile of the cutting edge could not be expressed with definite mathematics formulas, the nonlinear mapped characteristics of BP neural network were used to simulate the cutting edge in the method. The results indicated that this method not only accurately simulated the discrete coordinates to fulfill the task of accurate irregular cutting edge design, furthermore, the design of cutting edge was optimized, the accurate design of complicated irregular cutting edge with the aid of computer was fully achieved. Compare with the traditional methods of drawing and fitting of a polynomial, the method of BP neural network simulating can improve both the design precision and the working efficiency.
