· The reduced risk of thermal damage is linked with the lower grinding specific energies and the fact that a lower proportion of total grinding energy enters the work-piece when compared with an alumina wheel. The CBNs good thermal conductivity is the reason for this. (Mills B. et al. 1996)
Chat OnlineControl of thermal damage in grinding by digital signal
This work aims to investigate the efficiency of digital signal processing tools of acoustic emission signals in order to detect thermal damages in grinding process. To accomplish such a goal an experimental work was carried out for 15 runs in a surface grinding machine operating with an aluminum oxide grinding wheel and ABNT 1045 e VC131 steels.

Chat OnlineSpecific grinding energy causing thermal damage in
Thermal damage that occurs during machining processes is undesirable due to its detrimental effects. Grinding temperatures generated during grinding are a direct consequence of the energy input to the process. Grinding burn is one such type of thermal damage. Excessive grinding temperatures cause thermal damage to the workpiece.
Chat OnlineAn Advance in the Modelling of Thermal Effects in the
The proportion of the grinding energy entering the workpiece may be analysed either for the whole grinding wheel-workpiece contact zone or for the average grain contact zone which is two orders of magnitude smaller. An analysis which does not clearly apply to one zone or the other introduces conceptual difficulties since the relative speed seen by the workpiece is very different for the two cases.
