近几年我厂进行了一些钛合金的磨削加工试验。最近看到了美国波音公司的有关工艺资料,觉得我们的技术要求、工艺方法和他们比较还有一定的差距,有些地方我们可以借鉴。一、波音公司是按照零件的重要性来确定零件的疲劳特性要求,又根据疲劳特性来制订零件表面完整性:这样有较强的科学性。他们将表面完整性分为三级: In recent years I plant a number of titanium grinding test. Recently saw the United States Boeing related to process information, that our technical requirements, technology and their comparison there are still some gaps, in some places we can learn from. First, Boeing is in accordance with the importance of parts to determine the fatigue characteristics of parts requirements, but also based on fatigue characteristics to formulate the surface integrity of parts: This is more scientific. They classify surface integrity into three levels:
