  The mechanics of rock cutting - ScienceDirect

  197231 · Based on observation of the process of rock cutting and some simplifying assumptions a theory is developed on the mechanics of rock cutting. A formula for cutting force is proposed, which is similar to Merchant's well-known formula in metal cutting. Some experimental work was designed to cut plates of specimen rock, by an orthogonal cutting …
