镗削是机械加工的基本方法之一。通常对镗削加工出现的精度超差故障用工艺分析方法去探源,其结果并非理想,特别是对多工位镗孔。因此,近年有运用诊断技术求解这类精度故障的尝试。我们在这一实践中获益非浅,现以镗孔精度故障诊断原理及实例,阐述我们的见解。 一、镗孔条件与实际精度 某汽车制造厂加工一铝合金壳体,其形状及镗削 Boring is one of the basic machining methods. Often the boring process of the accuracy of the error tolerance process analysis method to explore the source, the result is not ideal, especially for multi-station boring. Therefore, in recent years, there have been attempts to solve such precision faults using diagnostic techniques. We have benefited immensely in this practice, now boring precision fault diagnosis principles and examples to illustrate our insights. First, the boring conditions and the actual accuracy of a car factory processing an aluminum alloy shell, the shape and boring
