Abstract: A method of bending sheet metal uses a test work piece of the same thickness and material as a finished piece. The test piece is bent into an angled form having an interior angle of any size. The interior angle is measured as are the height of each exterior edge above its opposite leg and the height of the apex of the angled form. Using these measurements, the interior radius of the angled form can be calculated as can the inner and outer lengths of the legs. Using these values the depth of a neutral line, which will have the same length in a work piece whether bent or not, can be determined. Once the depth of the neutral line has been calculated, a bend deduction for the final work piece may be determined and thus the required starting length is determined for any desired interior angle or leg lengths.

Abstract translation: 弯曲金属板的方法使用与成品相同的厚度和材料的测试工件。 试件弯曲成具有任何尺寸的内角的成角度的形式。 测量内角的方式是，每个外边缘高于其相对的腿部的高度以及倾斜形式的顶点的高度。 使用这些测量，可以像腿的内部和外部长度一样计算成角度形状的内部半径。 使用这些值，可以确定中性线的深度，其在工件中具有相同的长度（无论是否弯曲）。 一旦计算了中性线的深度，就可以确定最终工件的弯曲扣除，因此为任何所需的内角或腿长确定所需的起始长度。

Abstract: An angle detecting head provided with an emitter and a pair of receivers is rocked, and a bent surface of a workpiece bent by a punch and a die of a bending machine is irradiated with a measurement light from the emitter, a reflected light is received by the pair of receivers, and a bending angle of the workpiece is obtained from a peak value of the light received by the respective receivers. The angle detecting head is movable parallel to the die, is movable in a direction close to and away from the workpiece, and is movable in a direction in which the die is raised/lowered. The angle detecting head is positioned in an optimum angle measurement position of the workpiece and the bending angle is measured. Moreover, the bending machine presses the workpiece to the vicinity of a target angle, measures the bending angle of the workpiece during final pressing, removes pressure to bring the workpiece to an unloaded state, measures the bending angle of the workpiece, and obtains and stores a difference between the final pressing angle measured value and the unloaded angle measured value as a spring-back amount.

Abstract: A numerical control device for a bending machine includes a keyboard, a memory and a processor. The memory stores one or more groups of data, each containing bending conditions, a bend angle and at least one penetration depth. The memory further stores program instructions for searching whether data input with the keyboard is stored in the memory, in a same group of data, and that sends a signal to the bending machine so that the bending machine peforms bending according to the penetration depth included in the group of data. The processor that executes said program instructions.
