In order to evaluate the machining accuracy of part production in spline shaft grinding machine enterprise,the Fisher discriminant analysis method was used to evaluate the machining accuracy level of idle machine tool.The evaluation data were divided into evaluation standard data and sample to be evaluated.In order to ensure the correctness,the misjudgment rate test and significance difference test were carried out on the evaluation standard data,and the data was substituted into the linear discriminant function equation by using the algebraic method to obtain quantitative classification.The result shows that the evaluation standard data can be used as the evaluation criterion for the data to be evaluated,and the Fisher discriminant analysis method can reliably evaluate the machining accuracy.
