Test code for machine tools - Part 8 : determination of vibration levels

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). Additionally, ISO/TR 230-8:2009 discusses the application of artificial vibration excitation for the purpose of structural analysis.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
