A machine tool comprises a rotation driving unit (1) and reciprocation driving units (9,10). The tool (6) is moved against a workpiece (17) by the reciprocation driving units (9,10). The detection device (42) detects the magnitude of cutting resistance at the tool (6). The device (43) sets up the magnitude of cutting resistance according to the cutting methods of the workpiece (17). The control unit (31) controls the reciprocation driving units (9,10) according to the difference between the setting-up valve and the detecting value. |
