Abstract
Turbine blades play an important role as important parts in aero engines. One of the main methods of machining is electrochemical machining (ECM). In this paper, based on the flow field theory of electrochemical machining, the flow field analysis of machining gap was taken as the main research content When machining turbine blades. And the gap flow field model of blade electrochemical machining was established. Then based on COMSOL Multiphysics software, the distribution and characteristics of flow field were studied by numerical simulation of machining gap. Finally, the effects of different machining gaps and electrolyte pressure on turbine blade machining were analyzed, and the effects of electrolyte velocity and pressure on distribution were summarized. Keywords-Electrochemical Machining(ECM); Turbine Blade; Flow Field; Simulation
