The paper deals with cutting workpieces of Carbide and Superhard Materials Chip by the abrasive water jet of small diameter, give are some aspects of the stress state of the material under the action of the jet. It is shown that cutting superhard materials multi pass processing leads to an increase in the width of the cut and the emergence of some spatial errors. To improve the accuracy of performance slots, edges, holes in the slab is proposed to use a functional approach, based on the partition of the process into separate stages and to find appropriate methods of their execution. Thus, the change in the angle and speed of leakage bypass circuit can significantly improve the accuracy of processing. Found that the decrease in speed around the contour should be proportional to the thickness of the processed material and its physical and mechanical characteristics.
