金刚石线锯超声复合加工SiC-线锯受力分析及仿真研究的中期报告
摘要：
本文针对金刚石线锯超声复合加工SiC材料时的切削力进行了分析和仿真研究。首先，介绍了金刚石线锯超声复合加工的原理和优势，然后利用有限元仿真分析软件建立了钢丝锯切割SiC材料的模型，并对其进行了切削仿真和受力分析。仿真结果表明，刀具受力主要来自于材料在刀口处的切削力和摩擦力，在刀具与工件之间的接触面积越大，刀具所受力越小；而切削速度对刀具受力有较大的影响，速度较低时，刀具所受力较小，速度较高时，刀具所受力较大。因此，在金刚石线锯超声复合加工SiC材料时，应根据实际情况选择合适的切削速度和加工方式，以减小刀具的受力，提高加工效率和质量。
