主 题：Finite element simulation powder mixed electric discharge machining crater cooling rate stress experimental validation.
摘 要：This study reports the results of a finite element simulation of powder mixed electric discharge machining process for H11 Hot Die steel material using relevant boundary conditions and reasonable *** crater shape was developed using simulated temperature profiles to estimate the volume removed in a single *** temperature distribution on the workpiece was used to predict the cooling rate and calculate the stresses generated due to thermal ***,the simulation results were experimentally validated by physically measuring the crater shape and *** the results it was concluded that about 25%of heat is transmitted to the workpiece during machining at the process conditions used in the *** microscopic pictures showed bigger craters with increase in *** machined surface showed overlapping craters with surface cracks suggesting a high cooling rate.
