Abstract
It is indicated that in drilling holes in parts made of brittle nonmetal materials, the axial cutting force developed by the drill should be higher than the critical cutting force corresponding to the threshold of the brittle destruction of material. Amodel of slime removal from the cutting zone is developed ensuring the operation of the drill in the self-sharpening mode. Recommended pressure values for the lubricant-coolant supplied to the inner cavity of the drill are calculated based on the drill diameter.
