Field controlling electro-chemical honing(FCECH) machining mechanism and machining property of electrolyte

Field controlling electro-chemical honing is a new brand 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 surface 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. This method is suitable for machining workpiece with high accuracy and complicated shape. The machining mechanism of the method is discussed. Some new concept which makes the basic machining theory enriched and perfected is put forward ,and the basic requirements for the electrolyte are given out. By means of experiments, one of the five kinds of electrolytes has its own good feature, and their machining property under the condition of moving and slowly changing field is thoroughly investigated. It is found and proved that the moving speed of the electrolytical field has a notable influence on metal removal.
