Abstract
In order to solve the difficult problem in analyzing the shaping law of numerical control electrochemical machining (NC-ECM) with ball-end cathode, the process simulation based on the finite element method (FEM) is used in this paper. First, the two-dimensional analysis model of the electric field in NC-ECM with ball-end tool-electrode built by use of ANSYS software was solved, and the current density distribution and the machined surface shape on the workpiece were obtained. Then, the experiments based on the simulation parameters were carried out, and the cutting depth values were measured. Finally, the accuracy of the simulation was verified by the comparison between the calculated values and the actual values. The experiments showed that the simulation method meets the accuracy of the engineering calculations in NC-ECM.
