研究了电火花加工(EDM)技术的加工机理.以峰值电流、脉冲宽度、脉冲间隔、抬刀时间和加工时间为输入参数,并以加工速度和表面粗糙度为输出参数,分别用神经网络技术与非线性回归技术建立了EDM工艺模型.经过与实验数据的比较,认为这两种模型均能较精确地预测出给定条件下的加工速度和表面粗糙度,反映了该机床的加工工艺规律.其中,利用神经网络建立的模型具有更高的预测精度
The machining mechanism of EDM was studied. The peak current, pulse width, pulse interval, lift-off time and machining time were taken as input parameters, and the processing speed and surface roughness were taken as the output parameters. Neural network technology And non-linear regression technology established EDM process model.Compared with the experimental data, that both models can more accurately predict the processing speed and surface roughness under given conditions, reflecting the machine tool processing laws Among them, the model established by neural network has higher prediction accuracy
