根据斜角切削理论，假设将钻头主切削刃和横刃上的变形过程分别处理为一系列微小的具有动态特性的振动切削单元，从而构造出三区段振动钻削动态轴向力和扭矩的预报模型，并根据该模型对三区段动态轴向力和扭矩进行了计算机仿真。
According to bevel cutting theory, it is assumed that the deformation process on the main cutting edge and the chisel edge of the drill bit is respectively treated as a series of tiny vibration cutting units with dynamic characteristics so as to construct the dynamic axial force and torque of the three-section vibration drilling According to the model, the dynamic axial force and torque of three sections are simulated by computer.
