Development of Aerospace Flow Sensor in Stress-Free Machining Electrode Modules

Project Details


Electrochemical machining (ECM) has been increasingly recognized for micromachining of various parts. An Insulation coating process to erode a hole of hundreds of micrometers on a flow valve is analyzed in this paper. To enhance the controllability of the coating process, a model describing the relationship between the machining parameters and the produced hole profile is needed. The controlled factors include the gap between the electrode and workpiece, electrical voltage, the concentration of the electrolyte, machining time and electrode diameter. The experimental parameters are the electrical current, flow rate of the electrolyte, temperature and thickness of the workpiece. It is expected to greatly improve the processing accuracy and efficiency, improve the hardness and wear resistance and the coating with good thermal stability, meet the industrial application requirements, and promote the industrial technology upgrade.
