NdFeB材料电火花加工工艺效果的预测模型

Prediction Model for Technological Effect in the EDM Process of NdFeB

NdFeB材料由于高硬度、高脆性的特性,常规方法难以加工。电火花加工是加工硬脆材料的一种有效方法。为了实现高效、高质量的加工,对钕铁硼材料的电火花加工工艺规律需进行研究。本文中采用单因素实验法与正交试验法相结合进行实验设计。在大量试验的基础上,利用SPSS软件建立了电火花加工工艺模型。根据已建立的理论模型,对比回归结果与实际加工结果,验证了所建立的回归分析模型的合理性。通过设计新的实验,利用MATLAB软件预测电火花加工工艺效果,得出不同工艺参数下预测值与实际值相接近。

Generally, is difficult to machine with high hardness and brittleness. Electrical discharge machining is an effective method for NdFeB. In order to achieve high efficient and high quality, the technological rules in the EDM process of NdFeB is necessary. In this paper, the experiment planning is to combine the single factor experiment and the orthogonal experiment. The EDM process model is established by using SPSS software under a large number of experiments, the rationality of the regression model by compariing the regression results with the actual processing results is validated. By designing a new via MATLAB software and the predicted values are close experiment, the technological effects of EDM is predicted to the actual values under different process parameters.
