Abstract

In the present work, all steps involved in the measurement of Brinell hardness indentations were studied, with the main purpose of evaluating the contribution of each step to the total uncertainty of the process. For the measurement of the indentations an expert system using digital image processing was developed. This automatic procedure can be very helpful as it reduces by orders of magnitude the time needed to perform the measurements and makes the process more reproducible by reducing the influence of the human operator.
