A cutting method in which a workpiece (1) is cut on the basis of a plurality of tool paths (p1 to p9) parallel to one another into a shape having a corner (1c) that protrudes outward. A machining step for machining the workpiece (1) on the basis of one tool path and a moving step for moving to the starting point of the next machining step after the completion of the one machining step are repeated. In the machining step, a cutting step for cutting the workpiece (1) in the one tool path and a removing step for removing a burr (5) by moving a tool (41) relatively to the workpiece (1) in the same tool path as that of the cutting step in a region forming the corner (1c) are successively performed.
