| Abstract: |
| This paper aims to explore the influence of micro texture added to the cutting tool on the cutting performance. The cutting simulation and experiment are designed for the super-hard material tool with grooved micro texture. Based on the hydrodynamic jet and the secondary lubrication of fluid, the J-C criterion is used as the constitutive relation of turning, and ABAQUS is used to simulate the three-dimensional Al6061 cutting by the super-hard material tool with or without grooved micro texture under the same conditions, and the cutting performance is analyzed by combining the stress of the tool and the cutting temperature of the front face. A new type of grooved micro texture super-hard material turning tool has been prepared by femtosecond laser technology, and the single factor cutting experiment has been carried out on CA6136 lathe. When the grooved micro texture is added to the tool, not only the contact area between the friction pairs is reduced, but also the instantaneous high temperature phenomenon is alleviated under the dual action of the tool and the cutting fluid. Under the condition of dry cutting, the front face of the grooved micro texture tool does not have good anti-friction and anti-viscosity ability, and the tool wear is fast; the combination of cutting fluid lubrication and hydrodynamic jet and grooved micro texture can greatly reduce the friction and wear condition of the tool, and prolong the service life of the tool. The results of cutting simulation and experiment show that the micro texture can improve the cutting performance and reduce the tool wear. |
