摘　　要：建立了零件加工精度变化的预测模型,并用数理统计的方法对模型的精确性和适应性进行分析。以典型轴类零件(阶梯轴)为例进行了计算结果和实践数据对比,结果表明:通过模型模拟计算得到的结果和实际生产过程中零件精度的变化趋势非常接近,使用该模型能够很好的预测未来某一时期加工零件应达到的精度要求。Prediction model to calculate variation value of part precision characteristics was found.The accuracy and applicability of the model were analyzed by the method of mathematics statistics.The research result shows that data calculated by the model is very close to that of manufacture process.So it can be concluded that part precision characteristics in the future can be forecasted by the model.
