Abstract

This paper investigates an alternative method to assess thermal errors due to the heat generated by moving linear axes using a spindle-mounted probe and simple artifacts.  The angular errors introduced by the warm-up of individual axes (X, Y and Z) are obtained by probing multiple points on table mounted artifacts.  A discussion is presented of how the errors of the axes are estimated from changes in the location of points on artifacts.  Repeatability testing and comparison with data taken by an independent laser-based system verify the performance.  The paper describes the design of the test, sign conventions and analysis procedure.  The results show excellent repeatability and good correlation to data gathered with the laser-based system.
