摘要
为使叶栅通道粗加工余量更加均匀,针对某型整体叶盘,采用阴极斜向进给的加工方式设计了电解液流动方案,建立阴极在不同进给量下的三维流场模型,采用COMSOL Multiphysics软件计算不同加工阶段下电解液流场的速度和压力,并进行电解加工工艺试验.结果表明:加工过程稳定,无火花、短路现象,叶盘轮毂表面光洁,表面粗糙度为Ra=0.278 μm,验证了流场设计的合理性以及工装夹具的可靠性.
Abstract
In order to make the roughing allowance of cascade channel more uniform,the electrolyte flow scheme is designed for a type of integral blade disk by using the processing mode of cathode oblique feed,and the three-dimensional flow field model of cathode under different feed rates is established.The velocity and pressure of e-lectrolyte flow field under different processing stages are calculated by using COMSOL Multiphysics software.Fi-nally,the ECM process test is carried out.The results show that the machining process is stable,no spark,short circuit phenomenon,the surface of the blade disc hub is smooth,and the surface roughness is Ra=0.278 μm,which verifies the rationality of the flow field design and the reliability of the fixture.
