A lot of trial and observation to find hidden behind the statistical regularities in randomness

It is now the main focus has been aimed at the development of reliable data model system for processing prior to the cutting parameters were optimized. Here we use regression analysis method, a large number of experiments and observations to find hidden behind the statistical regularity in randomness, and ultimately to achieve the pre-processing design,  synthetic diamond the surface roughness purposes. Regression analysis is a mathematical method used, with the orthogonal polynomial regression and stepwise regression analysis and other methods of introduction, it is in the field of  abrasive grinding prediction is widely applied. Seeking optimal cutting parameters to control the surface roughness, people increasingly want to abrasive wheels with less build high precision surface roughness prediction model, to get rid of the passive situation of classical regression analysis, the initiative to arrange the test data processing and unify the accuracy of the regression equation to be considered.
