Abstract: An approach for predicting the friction performance of workpieces with grinding parameters was proposed to reduce the costs of surface profile measurement and development of friction and wear experiments. Considering the movement interference between the cutting edge of the grinding wheel and the workpiece, a model of the workpiece surface topography with the given parameters was established by combining the single-point diamond dressing; then the pressure distribution and friction coefficient of the grinding morphology were obtained by combining with the Reynolds equation under mixing lubrication. Simultaneously, taking machine guideway as an example, the model established above was validated. The analysis shows that the maximum friction coefficient can be obtained when the angles of the upper and lower surface textures are all 0°.
