Electrochemical machining process simulation for the blade of aviation engine with complex boundary plays an important role in the machining prediction. Traditional process simulation relies on finite element method which needs to solve the remeshing problem and computational accuracy problem. In this paper

we present an approach for improving the simulation precision based on isogeometric method

which employs NURBS basis function to replace the original Lagrange basis function in the finite element method and solves the Dirichlet boundary condition’s infliction problem. In the process of simulation

the corrosion displacement is translated into the displacement of the control point which avoids the computation time of remeshing and promotes the simulation precision

as demonstrated in the case of this paper.
