Simulation on numerically controlled electrochemical machining based on UG dynamic assemble

Based on the platform of Unigraphics (UG),with the secondary development tool UG/Open API and the method of dynamic assemble,a program is designed to simulate the process of numerically controlled electrochemical machining (NC-ECM). The NC track is checked,the gap between workpiece and cathode is estimated,and interference is detected. Then the simulation on the machining of material removal is completed,and a machined model is produced. The study provides a basis for the modification of NC code and cathode design,and for the machining. The key points to develop the program are emphatically discussed, and test machining is carried out.
