FIELD: machine engineering. SUBSTANCE: method comprises steps of preliminary setting on a test shaped charge on a construction to be cut or on a plate, having the same parameters; placing one end of the charge on a surface of the plate and spacing its second end from the surface of the plate by a distance, equal to doubled height of the charge; determining a distance from the test charge up to a surface of the construction or the plate in a zone of a total cut after an explosion of the test charge, placing an operating charge, being identical to the above mentioned charge, in such a way, that it is spaced by some distance from the surface of the construction, being cut. A value of that distance is equal to the distance from the test charge till the construction or till the plate in the zone of the total cut. EFFECT: enhanced accuracy of cutting efficiency. 1 cl, 1 dwg
