Abstract
The present invention provides a method and a system of on-line axial force detection for an electrochemical machining, which belongs to a machining clearance detection technology field. With an axial force transducer arranged between an electrochemical machining cathode and a principal axis of machine, force on the cathode surface exerted by an electrolyte action is transferred to the force transducer and a signal from the transducer can reflect the real-time machining clearance. Meanwhile, the present invention discloses the system of on-line axial force detection for an electrochemical machining which comprises a machine tool motion system, a transducer, a power supply for machining, a data acquisition and a processing device and an electrolyte supply system. The method and system are able to have on-line detection for the machining clearance and realize small clearance and high accuracy of the electrochemical machining.
Description
technical field [0001] The invention relates to special machining gap detection technology, more specifically, a method and system for detecting electrolytic machining gaps. Background technique [0002] Electrochemical Machining, also known as Electrochemical Machining (ECM), is a manufacturing technique that uses the principle of electrochemical dissolution of metal anodes to remove materials. Electrolytic machining is widely used in aviation, aerospace, military, weapons, shipbuilding, machinery, automobiles, medical equipment, electronics and other industries due to its advantages of fast processing speed, good surface quality, no macro cutting force, and no loss of tool cathode during normal processing. Department, mainly used for processing blades, barrel rifling, gears, splines, holes, cavities, deep holes, deburring, etc. Electrolytic machining has now become a key technology in the aerospace manufacturing industry, mainly used in the production of parts such as eng...
