利用有限单元法对锯切过程中锯片承受的应力分布状况进行分析，通过模态和屈曲分析，了解锯片厚度、转速、夹紧比和直径对锯切动态特性的影响。

• Analyze the stress distribution of the saw-blade during the sawing by Finite Element Method (FEM); study the influence of the thickness, rotary speed, clamping ratio and diameter of the saw-blade on its dynamic performance by modal and buckling analysis.
