摘要： A sheet material bending system includes a tool changing apparatus that changes tools between a press brake and a tool stocker. The tool stocker is arranged behind the press brake. To change tools from the front and rear of the tool stocker, the front and rear of the tool stocker are opened. The tool changing apparatus has a pivot that is movable in front-rear, left-right, and up-down directions and is rotatable around an axis extending in the up-down direction. A front end of the pivot is provided with tool holding units to hold tools.

摘要： A laser machining device includes a laser oscillator for oscillating a laser beam to have a variable output according to a machining condition, an optical fiber for propagating the laser beam, a sensor for detecting an intensity of a light leaking from a cladding side face of the optical fiber and outputting a detection signal indicating that intensity, and an oscillation control unit for controlling an operation of that laser machining device based on the detection signal. The oscillation control unit compares a first threshold that is set in correspondence to that output with an intensity or an amount of light obtained from the detection signal, compares a second threshold that is set in correspondence to that output with an intensity or an amount of light obtained from the detection signal, and controls the operation of that laser machining device based on a result of comparing.

摘要： A bending method for bending both sides of a major dimension portion of a workpiece to form flanges. The method comprises measuring a dimension of one bent flange and 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. If the measured value is below the object value, setting the object L value in the other flange processing to be over the flange dimension by a predetermined value. Bending is performed with the set object L value.

摘要： A dimensioning system is provided for a computer generated model of a sheet metal part including a plurality of entities. The dimensioning system comprises a model display, an indicator, a selector, a dimension defining system, and a dimension display. The model display displays a representation of the model on a display screen. The indicator indicates to a user candidate entities of the model, in response to user events, that may be selected. The selector selects two entities of the model, based on an indicated candidate entity. The dimension defining system defines each dimension associated with the selected entities of the model. The dimension display displays dimension information on the display screen based on the defined dimension. A repositioning system is also provided for a computer generated model of a sheet metal part represented on a display screen. The sheet metal part has associated dimensions displayed along with the sheet metal part on the display screen. The repositioning system comprises a repositioner and a repositioned dimension display. The repositioner repositions the dimension to a desired position relative to the model. The repositioned dimension display displays the dimension at the desired position relative to the model.
