    • In a measuring method in which a sizing device (10) is activated only for a prescribed measurement time (t 1 ) to carry out measurement in a main process that is repeated with a period of a prescribed process time (t 0 ), there are stored an activation drift that is a drift of a measured value after activation of the sizing device (10) and a deactivation drift that is a fluctuation in drifts among different elapsed times, each of the drift being measured when the sizing device is activated after a predetermined time has elapsed since the sizing device (10) is deactivated. A measurement drift section is determined. In the measurement drift section, the minimum value and the maximum value of the drift in the measurement time (t 1 ) in the activation drift are equal to the minimum value and the maximum value of the drift within a time (t 2 ) obtained by subtracting the measurement time (t 1 ) from the process time (t 0 ) in the deactivation drift, and the difference between maximum value and the minimum value is equal to or smaller than a prescribed value (E). The sizing device (10) is warmed up for a time (t D ) corresponding to a time from activation in the activation drift to the time at which the measurement drift section starts, and then the main process is started.

    • In bending a work, a temporary drive-in position of a ram is calculated from working conditions that are inputted from a working condition input section and information on the relationship of a spring back angle relative to a target bending angle of a work stored in a spring back data section, and the ram is driven to this temporary drive-in position, where a bending angle of a work is detected by means of an angle measuring unit. Following this, a final drive-in position of the ram is obtained from the bending angle so detected, relation ship of a ram drive-in amount relative to the work bending angle stored in a bending angle/drive-in amount data section and relationship of the spring back angle relative to the target work bending angle stored in the spring back data section, and then the ram is driven to a final drive-in position so obtained to thereby complete the bending process.
