DOTTO, Fábio R. L.; AGUIAR, Paulo Roberto de; THOMAZELLA, Rogério e BIANCHI, Eduardo Carlos. Methodology for automatic selection of passes in surface grinding. J. Braz. Soc. Mech. Sci. & Eng. [online]. 2007, vol.29, n.1, pp. 7-13. ISSN 1678-5878. http://dx.doi.org/10.1590/S1678-58782007000100002.
The main purpose of this work is the development of computational tools in order to assist the on-line automatic detection of burn in the surface grinding process. Most of the parameters currently employed in the burning recognition (DPO, FKS, DPKS, DIFP, among others) do not incorporate routines for automatic selection of the grinding passes, therefore, requiring the users interference for the choice of the active region. Several methods were employed in the passes extraction; however, those with the best results are presented in this article. Tests carried out in a surface-grinding machine have shown the success of the algorithms developed for pass extraction.
