摘要

This study analyzes the time dependent temperature distribution of the wire electrode along the wire axis by the finite-difference method. In the calculation, the heat transfer coefficient between the wire electrode and the working fluid and the energy distribution ratio are exactly determined based on the experimental results. Calculated results show that the means wire temperature increases with increasing the peak current and discharge frequency, and that the mean wire temperature is higher when the flow rate of the working fluid is lower and the thickness of the workpiece is thinner.
