Summary
The temperature rise, due to the passage of a grinding wheel, may have detrimental effects on the surface integrity of the outermost layers of the ground workpiece. In this contribution, a comparison has been made of various models, worked out for evaluating the heat affected zone. The predicted temperature fields and theoretically determined heat affected zones have been compared with experimental data.
From this evaluation, some factors have been put forward, which are relevant for practical grinding work. Of special interest in this respect is the work speed. In some cases, especially cut-off operations, also the infeed may become quite important. It might be possible indeed to increase significantly the efficiency of the operation, with respect to thermal damage by evacuating a large quantity of heat, simply by removing fast enough the heated-up material so as to minimize the heat conduction into the workpiece bulk material.
This kind of analysis may indicate further trends in cut-off operations, in high-speed grinding and in abrasive machining operations.
