Abstract


This article provides an overview of microfabrication technology application status , principles, characteristics and applications of ultrasound micromachining and electrolytic micromachining technology , analysis of problems and research prospects , analyze pulse ECM ultrasonic frequency vibration of composite electrolytic processing and ultrasound electrolytic composite the mechanisms and characteristics of micro-machining , discusses ultrasonic the electrolysis composite micromachining mechanism , technical advantage , given the test system constructed program to explore the workbench micro-displacement feed motion units , the effective supply of the the the cathode tool head design and production process , working solution step of the process , process parameter detection , display and processing accuracy measurement . Used in the field of micro manufacturing processing tools small size , the production of high precision , difficult . Tiny cathode design of the tool head is one of the difficulties of the key technology of ultrasound electrolytic composite microfabrication . Designed a variety of cross-sectional shape of the cathode tool head , perfect WEDM , EDM translational anti Khao sets of materials, conversion of inner and outer fine craftsmanship cathode tool head , produced a number of test and actual processing fine cathode tool head can meet the test requirements of complex microfabrication . Different materials the single ultrasonic machining test Carbide YT15 and YG8 of a single pulse ECM , ultrasonic frequency vibration composite electrochemical machining ultrasound of electrolytic composite microfabrication contrast test to further verify the feasibility of the complex process , reliability and technical superiority , composite microfabrication process indicators factors (such as: the electrolytic machining parameters , the ultrasonic amplitude a and frequency f feed pressure and abrasive particle size ) and variation to optimize the processing parameters , and use the preliminary parameters optimized processing the tiny gear specimen . Process phenomena and the main problem for processing test , and gives the corresponding solution envisaged Ultrasonic Electrolysis complex microfabrication method in the follow-up study of difficult to machine brittle conductive material of high-precision 3D microfabrication field content future prospects of its application .
