FIELD: tools.
SUBSTANCE: method involves making holes by edge tool, mainly, by twist drill. Then the treated hole surface is subjected to short-term heating to softening of a near-surface binder layer and uniform mechanical pressure is simultaneously applied to the treated surface. Instrument for implementing the method is made in form of twist drill with working edge part and cylindrical shank. Drill is equipped with a forming cylindrical section adjoining the working part, length of which is not less than treated hole depth. Forming cylindrical section diameter is 0.05…0.2 mm larger than drill working part diameter. Transition from the working edge part to the forming cylindrical part can be conical.
EFFECT: higher quality of processing parts surfaces from fibrous polymer composite materials due to fluffiness decrease and accompanying labor productivity increase.
