标准范围
ISO/TR 230-8:20 09涉及在机床的工具保持部分和工件保持部分之间可能发生的不同类型的振动。（为了简单起见，这些通常分别被称为“工具”和“工件”。）这些振动会对可接受的表面光洁度和精确的工件的生产产生不利影响。ISO/TR 230-8:20 09主要针对的不是那些在振动分析方面有专业知识并且经常在研究和开发环境中进行此类工作的人。因此，它不能取代关于这一主题的标准教科书。然而，它是为具有一般工程知识的制造商和用户设计的，以便通过提供相关背景理论的概述来增强他们对振动原因的理解。它还提供了评估可能困扰机床的某些类型振动问题的基本测量程序:由于机械不平衡而发生的振动；机器线性滑块运行产生的振动；外力传递给机器的振动；切割过程产生的振动包括自激振动（颤振）。此外，ISO/TR 230-8:20 09讨论了人工振动激励在结构分析中的应用。
ISO/TR 230-8:2009 is concerned with the different types of vibration that can occur between the tool holding part and the work-piece holding part of a machine tool. (For simplicity, these will generally be referred to as “tool” and “work-piece”, respectively.) These are vibrations that can adversely influence the production of both an acceptable surface finish and an accurate work-piece.ISO/TR 230-8:2009 is not aimed primarily at those who have expertise in vibration analysis and who routinely carry out such work in Research and Development environments. It does not therefore replace standard textbooks on the subject. It is, however, intended for manufacturers and users alike with general engineering knowledge in order to enhance their understanding of the causes of vibration by providing an overview of the relevant background theory.It also provides basic measurement procedures for evaluating certain types of vibration problem that can beset a machine tool:
- vibrations occurring as a result of mechanical unbalance;
- vibrations generated by the operation of the machine's linear slides;
- vibrations transmitted to the machine by external forces;
- vibrations generated by the cutting process including self excited vibrations (chatter).
