Research on Tool Cutting Performance and Turning Simulation
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=5A/mm2,15 A/mm2and 35 A/mm2)processing and untreated tool was compared.The results showed that after the treatment of pulse current,when the current density J increases from 5 A/mm2 to 35 A/mm2,the hardness of small cylindrical sampleandthetransverse 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 andslip,high density dislocation cell is formed within the material,so thatthe mechanical properties increase significantly.The simulation study of turning processingbased on finite element analysis software Deform 3D.The size distribution of cutting force was simulated,the simulation results and the test results were comparedand analyzed,whichprovided guiding significance for the determination of process parameters
