Resumen
The behaviour of the wheel when grinding stems in a way from the nature of its granular structure. Current grinding wheels are porous conglomerates of hard abrasive grains bonded by the formed by the binder. The characteristics of the abrasive grits, the resistance of the bonding material, together with the porous network, deter-mines wheel’s performance. The know how of wheel manufacturers is kept zealously in secret. The mechanical properties of the wheel, as an engineered material, should be able to be predicted in advance. However, its complex heterogeneous nature hinders the modelling. Recently, the discrete element method has been successfully applied in the modelling of the grinding wheel. This paper describes the proper creation proce-dure of the model. The work includes the calibration procedure of mechanical proper-ties due to homogenisation.
