Research on Modeling of Overlapping Erosion Pits in WEDM Based on Moving Heat Source
In order to conduct in-depth research on predicting the material removal amount and sur-face roughness of the workpiece after multiple discharges in WEDM through simulation.The temperature field was simulated using finite element software ANSYS,and the simulation results were post-processed and a geometric model of a single corrosion pit was established.Using Lab VIEW software,the distribu-tion of discharge points was collected during the experimental process.The discharge point data was im-ported into the UGNX platform,and combined with a single corrosion pit model,the actual distribution of the corrosion pit model relative to the workpiece was obtained.This method provides a new approach for predicting material removal and surface roughness of workpiece.
