摘要： A press brake is provided for bending a work accurately. An engagement position relationship between upper and lower molds is controlled based on a D value indicating a theoretical engagement position relationship between upper and lower molds which correspond to a target bending angle for actually bending a work, a theoretical machine deflection is calculated based on a theoretical load for performing bending to an average value for bending angles, an actual machine deflection is calculated based on an actual pressure by a hydraulic cylinder and a correction amount of the D value is calculated based on the difference between the theoretical machine deflection and the actual machine deflection. In addition, not only the bending angle accuracy relative to various bending conditions is to be improved but also the number of corrections is to be reduced. A device for calculating a distance D value comprises input means for enabling the input of work material, tensile strength, plate thickness and so forth, work winding judging means, spring back amount calculating means, an air bend, bottoming judging means, work holding angle calculating means, means for calculating a pressuring force when a work is held, and table travelling value calculating means.

摘要： Working factors which influence a bending angle are specified from data sent from an NC device (10) in a grouping factor specifying section (13), and a tolerance at the time of grouping is set for the specified factors in a tolerance setting section (14), whereby grouping of corners to be bent is performed in a corner grouping section (15). Compensating conditions are then set in a compensating condition setting section (16), and compensating data for a depth amount is calculated based on actual depth data of a corner bending performed on a good product in a compensating data calculating section (17) based on the compensating conditions so set, and process data of the bending process is changed in a process data changing section (18). Thus, the depth amount of a corner to be bent is compensated whose bending angle measurement is not performed based on a compensating value for a depth amount of a specific corner to be bent for which a bending angle has actually been measured.

摘要： An upper metallic mold is lowered to an unloading starting position for detection of a bending angle theta 1 of a work, and then is moved up at a very low speed so that, at the time of the ascending, positions of vertical movement of the upper metallic mold and a pressure force applied to a work, respectively, are successively detected. Then an increment of a forming force per unit ascending distance of the upper metallic mold is successively calculated, a bending angle of the work is detected at a point of time when an incremental value of the forming force converges to a particular value, relationships between a bending angle and a position of the upper metallic mold and between a forming force and a position of the upper metallic mold are linearly approximated from respective data of a bending angle and a forming force after that point of time, and a position of the upper metallic mold in which the forming force becomes zero is calculated on the basis of this approximate expression to estimate a bending angle theta 4 of the work at the calculated position of the upper metallic mold. Then, a difference theta 4 - theta 1 between the estimated bending angle theta 4 and the bending angle theta 1 at the unloading starting position is assumed to be an angle of spring back.

摘要： 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.

摘要： 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.
