Abstract
As the complexity of machined parts increases and
geometric tolerances become more challenging, the need be able to
verify geometric errors within five-axis machine tools has never
been greater. A body of research has been undertaken to demonstrate
that the telescoping magnetic ballbar may be used in five-axis machine tool accuracy testing, leading to its recent inclusion in international standards. This paper highlights the fact that geometric errors within linear axes can lead to the falsification of rotary axis error diagnosis. In response, this research identifies a method through which to compensate the effects of linear axis errors from the measurements taken during rotary axis testing. Through experimentation, it is shown that linear error effects may be almost entirely removed from tests that identify radial offset errors, and significantly reduced in tests to identify rotary axis tilt errors. It is proposed that this research has significant potential in machining high-value and complex components, where frequent checking of machine tool geometric errors is required.
