可控电解珩磨准稳态加工去除规律模型参数的确定

可控电解珩磨的本质就是实时变化电场控制的电化学机械复合加工方法，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。针对建立的准稳态加工条件下去除规律的基本模型，通过实际加工中去除实验的分析与综合，利用最小二乘拟合方程确定基本模型中的相应参数，建立了一定加工条件下去除规律的实用数学模型。

Mathematical models of quasi\|stable machining removal in Field Controlling Electro\|Chemical Honing

Field Controlling Electro\|Chemical Honing (FCECH) is a new brand of machining method. Microcomputer is in real time controlling the electrolytical field at the electro\|chemical dissolution spot of workpiece which is scanning over the workpiece during the machining process, so that the rate of metal removal is varying during the scanning and required geometry of the workpiece can be obtained. Aiming at the basic mathematical model of quasi\|stable machining removal law which has been built up, analyzing and synthesizing the experiment of practical metal removal, using least squares regression to work out the parameters in the basic mathematical model of quasi\|stable machining removal law, the practical mathematical model has been established in a certain machining situation.
