PROBLEM TO BE SOLVED: To provide a machine tool and a machining method capable of measuring a position of a cutter tip without causing an error during machining, monitoring a product after machining, and measuring a tool wear amount. SOLUTION: This machine tool has a tool 6, ball screws 9, 12 and motors 10, 13 for driving a turret 7 provided with a position measuring sensor 5 having a detection part in the directions of X- and Z-axes, position detection encoders 11, 14 for detecting positions in the directions of X-and Z-axes of the turret 7 and a linear scale 15 for detecting X-axis position; a sensor 16 for measuring a cutter tip position for measuring positions in the directions of X- and Z-axes of the cutter tip of the tool 6 in contact, an NC device 19 for obtaining a position of the sensor 16 for measuring a cutter tip position based on a position of the detection part for a position of a main spindle detected by bringing the detection part into contact with a reference object 20 for sensor calibration for measuring position and a position of the detection part detected by bringing the detection part into contact with the sensor 16 for measuring a cutter tip position, and a tool wear amount measuring part having a common reference face 22 for measuring a tool wear amount to measure positions of the cutter tip and a workpiece before and after machining.
