In internal grinding with axial feed, each double pass begins with insertion of the grinding wheel in the workpiece in the reversing zone, by means of a radial insertion feed; the axial feed in this process is zero. Therefore, at that stage, the cutting conditions are fundamentally different than in machining the remainder of the hole, when the axial feed is nonzero. As a result, in the reversing zone, the quality of machining is significantly different from that for the remainder of the surface. A methodology is considered for optimization of the parameters at wheel insertion, for the example of internal grinding with axial tool feed. Dynamic programming is used for optimization.
