Abstract: A method for modifying a stamping die to compensate for springback includes the steps of stamping a first part using a base, or pre-existing die set, and creating a surrogate die having the shape of the first stamped part. These steps are followed by simulated stamping of a blank with the surrogate die, where the blank is shaped according to the desired finished part. Then, the base die is modified by mapping the forming stresses, from the stamped blank, to an indicator blank, which is allowed to relax and then is employed as a template for modification of the base die. Following this, the accuracy of the newly modified base die is determined by stamping a second part in the modified base die and by comparing a number of dimensions of the second part with a number of corresponding dimensions of the desired finished part.

Abstract: A major object of the present invention is to compensate for variations in springback angle resulting from variations in material properties from one lot to the next, for the realization of high angle accuracy bending. Based on the difference between a workpiece actual bend angle detected during bending and an estimated bend angle of a workpiece W at an arbitrary penetration point of an upper die 5, a correction value for prestored data relating to a springback behavior under a processing condition is obtained. Based on the correction value, a final penetration point of the upper die 5 is obtained.

Abstract: A method and related system for operating a computer controlled press brake system to form a requested bend angle in a workpiece are described. According to the disclosed method, values corresponding to geometrical characteristics of the press brake and a first workpiece are stored, as is a value for the requested bend angle. A ram of the press is operated in a first direction, relative to the die, to a first selected position to bend the first workpiece and to hold the first workpiece to a restrained bend angle. The ram is thereafter operated in a second direction to release the first workpiece to an unrestrained bend angle. The difference between the restrained and unrestrained bend agles of the first workpiece is calculated. Using the values for geometrical characteristics and the requested bend angle, a correction factor is calculated. In accordance with the correction factor, the unrestrained and requested bend angles, the ram is set to travel to a corrected position. The ram is operated to the corrected position to bend a second workpiece, substantially identical to the first workpiece, to bend the second workpiece to the requested angle.

Abstract: The present disclosure provides a navigation method and system which does not require a remotely located tracking system, or additional targets or other devices to be installed on the patient or object being tracked. The system uses one flexible component in physical contact with the patient/object and measures relative position as a function of forces that are generated by the flexing component as it is bent. The system translates forces into navigational commands for a robot, other manipulator, or for human manual navigation. A method for transforming a pre-planned motion pathway into a sequence of forces for this mode of navigation is also described. This system is also applicable in the field of manufacturing robotics, where the locations of objects or assemblies may not be precisely known or constant. The method and system disclosed herein can be used to maintain known position of an object/assembly or to navigate movement of a robot relative to an object/assembly as in the case of machining.
