Based on the process property of WEDM,the cause of eccentric traveling distance of electrode-wire is analyzed.The calculation principle and method of the real machining path for electrode-wire center-line on WEDM NC-programming is introduced.It presents the process points of determined threading wire hole and fined wire cut path.According to the particular process pass of die parts in machining,the treatment measures are proposed and so it improves the machining accuracy and product quality.Then it enhances production efficiency in die and mould wire-cut machining.
