| 摘 要： | 应用位错理论及ＳＥＭ观察,超声波振动切削由于附加了超生能量以激励起刀具的谐振,从而变静态刀具为以超声波频率冲击切削区的动态刀具而起作用,基冲击应力波可导致高的静态剪应力,激活位错,软化丸前材料,使材料易于成屑,并通过实验证明超声波振动切削具有传统的机械加工不可比拟的优异工艺效果。

| Abstract: | According to dislocation theory and SEM observation, the dislocation mechanism of form into chip in ultrasonic wave vibration cutting is studied. Because ultrasonic energy is added into the cutting in UWVE, the tool's syntony is inspired. This changes the "static" tool into a "dynamic" one, which is impacting the machined area. Its impact wave may lead to high static shear stress, the value of which is greater than that of static shear stress,activate dislocation, soften the cut material adjacent to the cutting tool edge and form the chip easily. Test certifies that ultrasonic wave vibration cutting has better technical effects than traditional machining. |
