PROBLEM TO BE SOLVED: To provide a machine tool and a cutting method by which accurate cutting processing can be performed by improving movement accuracy of a cutting tool even in a time until a guide and a guided part are in an equilibrium state, and efficiency of an operation time can be improved.SOLUTION: A machine tool includes: main shafts 20, 30 which hold a workpiece W and rotate; tool rests 40, 50 which hold cutting tools 40b, 50b for cutting the workpiece W; rails (guides) 44, 54 which guide guided parts 42, 52 arranged on the tool rests 40, 50 or the main shafts 20, 30; drive parts 43, 53 which relatively moves the tool rests 40, 50 and the main shafts 20, 30 in a direction of guiding the guided parts 42, 52 by the rails 44, 54; measurement parts 45a, 45b, 55a, 55b which measure temperatures of the rails 44, 54 or the guided parts 42, 52; and a control part 60 which sets a correction value related to the movement of the main shafts 20, 30 or the tool rests 40, 50 in response to measurement results of the measurement parts 45a, 45b, 55a, 55b, and drives the drive parts 43, 53 by using the correction value. |
