Claims
- 1. A bending method for bending both sides of a major dimension portion of a workpiece to form flanges, comprising:
measuring a dimension of one bent flange;
setting an object L value in an other flange processing to be below a flange dimension by a predetermined value, if the measured value is over an object value; setting the object L value in the other flange processing to be over the flange dimension by a predetermined value if the measured value is below the object value; and performing bending with the set object L value.
- 2. A bending method for bending both sides of a major dimension portion of a workpiece to form flanges, comprising:
measuring a dimension of one bent flange;
inverting the workpiece when a dimension of said major dimension portion is within a tolerance and if a dimension of the other flange is the same as the dimension of said one bent flange; and bending the workpiece with the same L value.
- 3. A bending method for bending both sides of a major dimension portion of a workpiece to form flanges, comprising:
measuring a dimension of one bent flange;
assuming a dimension of said major dimension portion to be an object L value if the measured value is within a tolerance; and bringing said one bent flange into contact with end gauges for bending.
