In order to study the effect of pulse current treatment on tool cutting performance of cemented carbide, on the basis of cutting experiment, the cutting performance of tool was treated by different current density (J=5 A/mm2, 15 A/mm2 and 35 A/mm2)processing and untreated tool was compared. The results showed that after the treatment of pulse current, when the cunent density J increases from 5 A/mm2 to 35 A/mm2, the hardness of small cylindrical sample and the transverse fracture strength of cuboid sample was improved than that untreated sample; the cutting performance increased 5.6%, 8.2% and 10.8% than that untreated tool, tool life has been improved. After the treatment of pulse current, pulse current provides the driving force for dislocation motion, strong driving force is more likely to make the dislocation multiplication and slip, high density dislocation cell is formed within the material, so that the mechanical properties increase significantly. The simulation study of turning processing based on finite element analysis software Deform 3D. The size distribution of cutting force was simulated, the simulation results and the test results were compared and analyzed, which provided guiding significance for the determination of process parameters
