Notes:
When the Neural Network model is used to interpolate the non-circular curves, there areshortcomings of converging slowly and getting into the local optimum easily. A novel numericalcontrol interpolation algorithm based on the GA (Genetic Algorithms) and NN (Neural Network)was introduced for the ultra-precision machining of aspheric surfaces. The algorithm integrated theglobal searching of GA with the parallel processing of NN, enhanceed the convergence speed andfound the global optimum. At the end, the quintic non-circular curve was taken as an example to dothe emulation and experiment. The results prove that this algorithm can fit the non-circular curveaccurately, improve the precision of numerical control interpolation and reduce the number ofcalculating and interpolation cycles
