Description

technical field [0001] The invention relates to a device and a method for simulating the rotary printing electrolytic dissolution process of rotary parts with flat electrodes, which belong to the technical field of electrolytic processing. Background technique [0002] Electrolytic machining is a special machining method that uses electrochemical reactions to quickly remove workpiece materials. Compared with traditional machining, electrolytic machining is a non-contact machining, which has the advantages of no tool loss, no residual stress, no cold hardening, no plastic deformation, and low surface roughness during the machining process. Therefore, electrolytic machining is suitable for processing thin-walled parts, space-complex curved surfaces, and difficult-to-cut superalloy materials. [0003] As an important part of an aero-engine, the casing is a large thin-walled part with a complex concave-convex profile. High, and after the workpiece is processed, the residual st...

Problems solved by technology

In the state of periodic low-frequency, low-duty-cycle pulse processing, the electrolytic dissolution behavior of anode materials, especially metals that are easily passivated, is different from conventional DC and pulse electrolytic machining, which will produce abnormal dissolution behavior, which will seriously affect the quality of the machined surface and machining accuracy.
