We have obtained the equation of the temperature field in a workpiece surface at a round plunge grinding, taking into account different heat transfer in and out of a fast-moving heat source at multiple rotating of a part. It was found that accumulation of heat from turn to turn almost does not occur. To eliminate doubts about the fairness of the result, due to the simplification of the problem of heat conduction by replacing of the moving heat source by a fast-moving one, we have obtained the solution for a moving heat source taking into account different heat transfer in and out of the source. This solution allows one to get the temperature field in a workpiece only in a time of one rotation. The comparison of the results of this solution with the results of the solution from a fast-moving source shows their almost complete agreement. It permits to suggest that there are no reasons to expect a significant difference in the solutions of problems of heating with moving and fast-moving heat sources for a few rotations. Thus, the design of the plunge grinding cycle while limiting its modes by the maximal heating temperature can be made on the basis of the heating of a part per one rotation.References
