一、七十年代国外金属切削与表面完整性技术的发展概况金属切削是机械制造工业中应用最广泛的加工方法。各国都以大量的人力和资金从事这项研究发展工作。据统计,美国每年单是为操作切削机床所支付的工资和其他各项研究费用就达400亿美元,以不断提高各工业部门金切劳动生产率和降低加工成本。六十年代末期,国外陆续采用高压透射电镜、扫描电镜、电子光谱仪、电子探针显微分析、离子探针质谱仪、x射线应力分析仪和衍
I. The Development of Overseas Metal Cutting and Surface Integrity Technology in the Seventies Metal cutting is the most widely used processing method in the machinery manufacturing industry. All countries are engaged in this research and development work with a lot of manpower and funds. According to statistics, the United States alone pays 40 billion U.S. dollars each year for wages and other research costs incurred in operating cutting tools to continuously improve the labor productivity of the various industrial sectors and reduce the processing costs. In the late 1960s, high-pressure transmission electron microscopy, scanning electron microscopy, electron spectroscopy, electron probe microanalysis, ion probe mass spectrometer, x-ray stress analyzer
