摘　　要：可控电解珩磨是以微机实时控制电解珩磨过程中工件表面的电解电场强度，从而调控各点金属去除速度，获得工件要求几何形状精度的新加工方法．通过大量的实验研究，提出了加工过程中金属去除的三种分布密度函数，建立了针对三类复杂曲面工件在准稳态加工条件下的去除规律数学模型和对应施电规律的去除量分布计算方法．Field controlling electrochemical honing(FCECH)is a new brand machining method.Microcomputer is in real time controlling the electrolytical field at the electro-chemical dissolutionspot of workpiece which is scanning over the workpiece surface during the machining process, sothat the rate of metal retnoval is varying during the scanning and required geometry of theworkpiece can be obtained. By means of the deeply experimental researches,three kinds ofdistributing density functions of metal removal of FCECH are presented.The mathematic modelsof metal removal law under the quasi-stable machining condition which are suitable for threetypes of workpieces with complicated shape are established. And the calculating method forremoval distribution corresponding to certain electrochemical dissolution current law applied is putforward.
