On reduction of energy flow into workpiece in continuous generating grinding

Owing to intense heat generation in the continuous generating grinding, a large amount of grinding fluid is supplied during the process. Recently, however, reduction in grinding fluid supply has been attempted. In this study, the specific grinding energy and heat partition ratio of continuous generating grinding was ana-lysed under dry conditions. The results revealed that the specific energy reduced to 53.8% with the grinding wheel of nine starts compared to that of three starts. The heat partition ratio remained almost unchanged with varying number of starts. The results revealed that a wheel with higher number of starts is thermally beneficial.(c) 2022 CIRP.

Automated summary

This study analyzed the specific grinding energy and heat partition ratio of continuous generating grinding under dry conditions. The results showed that a grinding wheel with more starts had a lower specific energy, while the heat partition ratio remained almost unchanged.
