Structural Parameter Optimization of Solid Ceramic End Milling Tool Based on AdvantEdge and Experimental Verification
In this paper,the influence of different structural parameters (radial rake angle of circumferential cutting edge,radial clearance angle of circumferential cutting edge and helix angle) of the solid ceramic end milling tool on the milling force is studied by finite element simulation.The tool structure is optimized by orthogonal test.The milling perform-ance of the solid ceramic end milling tool before and after structural optimization is compared and analyzed,the wear mech-anism and failure modes of the tool are explored.The results show that the radial rake angle of the optimized tool is-8°,the radial clearance angle is 10°,and the helix angle is 40°.The tool life after structural optimization is increased by 42.9％,the flank wear is reduced by 37％,and the machined surface roughness of the workpiece is reduced by 5.5％.The wear mechanism of the tool is mainly adhesive wear and diffusion wear,the failure modes are mainly spalling,micro-cracks and chipping.The tool wear phenomenon after structural optimization has been significantly improved.
