FIELD: plastic working of metals, possibly in aircraft making industry, power machine engineering for making blanks of blades, for example of compressors of gas turbine engines.
SUBSTANCE: method comprises steps of deforming ingot by lengthwise rolling for producing plate whose thickness is no less than maximum thickness value of stem of blade blank; crosswise dividing plate by strips whose width is no less than predetermined maximum length of blade blank; deforming strip in cross direction relative to axis of plate for producing H-shape having thickness of bridge no less than predetermined maximum thickness of blank blade; then separating H-shape by fragments whose length is no less than predetermined maximum width of stem of blade blank. Cross deforming of strips is realized by rolling or drawing process.
EFFECT: lowered labor consumption at making universal working equipment, enhanced operational reliability of blades, improved factor of material usage.
