The choice of proper working conditions is a problem for any processing. But for laser processing this procedure is much more serious. The final results of the processing are usually influenced by more than 100 factors. So the best way to choose the working conditions more cheaply and fast is to use the processing simulation. Different tactics of this procedure is discussed and the statistical modelling is accepted. The actual model for laser cladding is developed based on the experimental results of 2Cr13 stainless steel cladding with diode laser robotized system. This model is optimized and verified by experimental results, and then is used to find the optimal processing parameters for laser remanufacturing on 2Cr13 turbine blade. In the light of the lost sizes and required property, this statistical model contributes to repair the failed turbine blade by diode laser robotized system with high efficiency.
