PROBLEM TO BE SOLVED: To provide a method of machining the inner peripheral surface of a circular hole, uniformly removing swells formed at the edges of recesses in forming fine recesses on the inner peripheral surface of the circular hole of a workpiece. SOLUTION: Honing is performed as pre-machining to the inner peripheral surface of a cylinder bore, and then the fine recesses are formed on the inner peripheral surface of the cylinder bore. Honing is then performed as post-machining to the inner peripheral surface of the cylinder bore to approximate the circle form of each cylinder bore after honing before and after forming the recesses. Machining allowance by honing of post-machining is made uniform over the whole periphery of the cylinder bore to uniformly remove the swells formed at the edges of the recesses.
