1. the slewing (26 of a protection lathe (15);

  • 13) method, this device loads has temperature, and this lathe has at this equipment (26;

         13) temperature sensor (14) on and temperature frame (16), the method comprising the steps of;

    Input special parameter in temperature frame (16);

    For a temperature value (18) is estimated in the device temperature rising that the activity (19) by equipment causes;

    Measure the temperature (20) of this equipment (26);

    Be offset measuring temperature by the temperature value according to this estimation, eliminate the temperature value of estimation and the normal difference between the measurement temperature;

    When the difference signal between the measurement temperature of the temperature value of the estimation that finally obtains and skew surpasses a filp-flop stage, produce event signal (4).
