Abstract

AGUIAR, P. R. de; DOTTO, F. R. L.  and  BIANCHI, E. C.. Study of thresholds to burning in surface grinding process. J. Braz. Soc. Mech. Sci. & Eng. [online]. 2005, vol.27, n.2, pp.150-156. ISSN 1678-5878.  http://dx.doi.org/10.1590/S1678-58782005000200007.

This work aims at finding out the threshold to burning in surface grinding process. Acoustic emission and electric power signals are acquired from an analog-digital converter and processed through algorithms in order to generate a control signal to inform the operator or interrupt the process in the case of burning occurrence. The thresholds that dictate the situation of burn and non-burn were studied as well as a comparison between the two parameters was carried out. In the experimental work one type of steel (ABNT-1045 annealed) and one type of grinding wheel referred to as TARGA model 3TG80.3 - NV were employed.

Keywords : Grinding; monitoring; burning; acoustic emission; electric power.
