1. lathe of when moving cutter according to process data with respect to workpiece described workpiece being processed is characterized in that:

  • Temperature sensor (28-36) is arranged on a plurality of parts of machine body (11,41), is used for measuring respectively the temperature of each several part;

    Displacement detector (25) according to the measurement of described temperature sensor (28-36), obtains the heat displacement amount of each parts (12-15) of the described machine body of composition (11,41);

    Converting unit (25), described converting unit converts the heat displacement amount of described each parts (12-15) to displacement that processing stand (P) is gone up each axial direction;

    Amending unit (25), described amending unit is revised the amount of movement of each axis according to the conversion of described converting unit (25), wherein;

    At least on the second surface of the first surface of bigger each parts (12-15) of variations in temperature and each parts (12-15) relative, described temperature sensor (28-36) is set with described first surface;

    AndDescribed displacement detector (25) has been considered to have the prying that difference produced of temperature rise between the described first surface of big variations in temperature and the described second surface relative with described first surface and has been obtained displacement.
