Fast test method for the determination of the grindability ...
In case of fly ash grinding, the Universal Hardgrove mill test (torque measurement) and the energy measured ball mill method were carried out. The median value of feed was 26.26 μm (x 80 = 43.1 μm). From Fig. 6 it can be seen that linear function can be fit to the measured points of both grindability method.
Prediction of ball-end milling forces from orthogonal ...
The model is verified by conducting over 60 ball-end milling tests at different feeds, speeds, axial and radial depth of cuts and bail-end mill geometry. Statistical and sample time domain simulation results show that the approach can predict cutting forces accurately for any ball-end mill geometry and cutting conditions.
