Development and application of machining complex ruled surface technology by WEDM

In order to solve the problem of machining complex ruled surface parts, the complex surface WEDM system with a new type of roll-over automatic indexing CNC worktable was developed. The motion laws of machining complex ruled surface by multi-axis WEDM were analyzed, and the mathematical modeling of multi-axis WEDM system were fulfilled. The ideal simulation results can be obtained by computer simulation, and the ideal machining parameters obtained by computer simulation provide a theoretical basis for machining complex ruled surface. The two-axis roll-over automatic indexing CNC worktable was developed, the CNC system software of machining complex ruled surface by multi-axis were programmed, which possess stable machining performance. The ideal complex ruled surface parts can be machined by combining the two-axis roll-over automatic indexing CNC worktable and the domestic high-speed WEDM machine tool. The above-mentioned works can solve the key technology problems from the root about machining complex ruled surface parts on the high-speed WEDM machine tool, extend the use range of WEDM and develop the machining complex ruled surface technology according to the situation of China.
