PROBLEM TO BE SOLVED: To lessen cutting errors as small as possible in cutting work using a lathe or the like. SOLUTION: In the cutting method for cutting a workpiece 1 by using a tool, after calculating edge force generated on the cutting tool 2, and rigidity of the cutting tool 2, a cutting machine for retaining the cutting tool 2 and the workpiece 1, the cutting errors E is calculated from the edge force and the rigidity, and an amount of infeed of the cutting tool 2 is compensated on the basis of the calculated cutting errors E. The cutting machine realizing such the cutting method comprises an error compensation section for calculating a compensating amount of the amount of infeed of the cutting tool 2 on the basis of the calculated cutting errors E by calculating the cutting errors E from the rigidity of the cutting tool 2, the cutting machine and the workpiece 1, and a control section for applying the compensated amount of the amount of infeed calculated by the error compensation section to the cutting tool 2.
