摘　　要：在刀具表面置入微织构是改善刀具加工性能的有效手段。为了研究微织构硬质合金立铣刀铣削高硅铝合金的切削力,开展了有限元仿真分析及铣削实验。结果表明,与无微织构刀具相比,微织构铣刀的切削力明显降低,且微织构的深度对切削力的影响最大。研究证实了在刀具表面合理布置微织构能够显著提高硬质合金铣刀的切削性能。The placement of micro-texture on the surface of the tool is an effective means to improve the machining performance of the tool.In order to study the cutting force of micro-textured cemented carbide end mills for milling high silicon aluminum alloys,finite element simulation analysis and milling experiments are carried out.The results show that the cutting force of micro-textured milling cutters is significantly lower than that of non-micro-textured cutters.Among them,the depth of the micro-texture has the greatest influence on the cutting force.Research confirms that reasonable placement of micro-texture on the tool surface can significantly improve the cutting performance of cemented carbide milling cutters.
