Abstract:The surface microtexture can improve the cutting performance of the tool. In order to study the effect of texture parameters on the cutting performance in high speed dry cutting of Al7075-T6 with textured cutting tools, an orthogonal twodimensional cutting simulation model was established by using the simulation software. The main cutting force, tool temperature and tool stress of the optimal texture tool within the selected texture parameter range were compared with those of the non-texture cutting tool , and the influence of texture parameters on the main cutting force was analyzed. The results show that the reasonable texture parameters can reduce the main cutting force of the tool and make the tool show better temperature and stress distribution gradient.Within the range of the selected texture parameters,when the texture width is 60 μm, the texture spacing is 90 μm, the texture depth is 30 μm, and the texture edge distance is 100 μm,the texture cutting tool has the best cutting performance.The influence degree of texture parameters on the main cutting force is the texture edge distance, texture width, texture spacing and texture depth in turn.
