Jamshidi, Hamid and Yastıkcı, Batuhan and Gürtan, Mert and Budak, Erhan (2017) Grinding force model for Inconel 718 with CBN and conventional wheels. In: 6th International Conference on Virtual Machining Process Technology (VMPT), Montreal, Canada
Grinding force plays crucial role in choosing grinding parameters since it can be used for predicting power, wheel wear, surface roughness, temperature etc. In this paper a force model was developed to predict average grinding force for Inconel 718 with electroplated CBN. Two methods, namely mechanistic and oblique cutting approaches were employed and results were compared with the experiments. There was a good agreement between predicted force in both approaches and experiment data although mechanistic approach gave a better prediction than mechanics of cutting approach. Furthermore, performance of CBN and aluminum oxide wheels was studied by comparing grinding force and force coefficients. Results showed that grinding with CBN wheel led to lower force and force coefficients.
