【摘要】 采用普通车削及振动车削方法对W-Fe-Ni合金材料进行了加工试验,分析了各切削参数、振动参数对加工表面粗糙度的影响程度,认为除进给量外,振动参数也是较显著的影响因素。通过X射线衍射仪、白光干涉仪、扫描电镜对试件表面进行显微形貌观测,证实了振动车削时刀具对加工表面的强烈熨压效应。结果表明,振动车削中,合理选择车削参数和振动参数可以获得良好的加工表面。更多还原

【Abstract】 The experiments of turning W-Fe-Ni alloy by conventional turning and ultrasonically assisted turning were carried out. The effect of cutting parameters and vibration parameters on surface roughness was analyzed. The significant factors influencing surface roughness are in the order of feedrate, amplitude and frequency of the tool. The X ray diffractometer, optical interferometer and scanning electronic microscope were used to observe the micro profiles of surfaces turned. With the observation results it was confirmed that ironing effect of tool to the surface turned was strong and the fine surface could be obtained by appropriately selecting parameters in ultrasonically assisted turning.更多还原
