【摘要】 使用硬质合金刀具进行69111不锈钢的高速干铣削试验。通过采用电子扫描显微镜(SEM)观察刀具的磨损形貌和能谱分析仪(EDS)分析磨损表面及磨损边缘处的元素分布,对刀具的前、后刀面的主要磨损机理进行了分析。研究结果表明:使用硬质合金刀具高速干铣削69111不锈钢时,刀具的前、后刀面的主要磨损机理均为粘结磨损、氧化磨损和扩散磨损;并且由于铣削过程中,刀具前刀面的铣削温度明显高于后刀面的铣削温度,导致前刀面的磨损程度较后刀面严重。更多还原

【Abstract】 Cemented carbide tool(YG8) was used to mill 69111 stainless steel at high-speed under dry cutting condition.Wear images of cutting tool was observed by SEM,and element distribution of tool surface and wear edge was analyzed by EDS.Experimental results show that:adhesive wear,oxidation wear and diffusion wear were the main wear mechanism of the cemented carbide tool.During milling,the cutting temperature of rake face was higher than that of flank face,so the wear of rake face was more serious in comparison with that of flank face of cutting tool.更多还原
