Specification for general requirements for titanium bolts Ingestion-build-276583 The tests for thermal drift

The tests for thermal drift of the axis drives apply to numerically controlled (NC) machines only and are designed to quantify the effects on positioning accuracy and repeatability of thermal expansion and contraction of the axis drives

the recommendations in BS 4479-9 are intended to provide guidance towards good practice when it comes the design of articles to be coated

a module with the same structure as the ready collector is tested

A full method applicable when the threshold number for the sample is to be determined
