Abstract

A traceable areal surface texture measuring instrument has recently been developed at the National Physical Laboratory (NPL). The instrument uses a stylus probe and the relative positions of the measured points on a surface are inferred from laser interferometers. This paper presents the method used to estimate the uncertainty associated with the new traceable instrument. A geometrical model of the instrument has been constructed and a Monte Carlo technique has been used to propagate the uncertainties associated with the point co-ordinate. This is analogous to the method used in coordinate metrology referred to as a 'virtual CMM' method. The mathematical model is presented along with the influence factors and some preliminary results.
