摘要： Flanges formed on sheet metal parts to increase the part stiffness or create mating surface for further assembly are created in an incremental sheet forming process using forming tool and supporting tool that move along a specified tool path so as to gradually deform a peripherally-clamped sheet metal work piece into the desired geometry. With two universal tools moving along the designed toolpath on the both sides of the part, the process is very flexible. Process time is can also be reduced by utilizing an accumulative double-sided incremental hole-flanging strategy, in which the flange is formed in only one step.

摘要： A compact deformation-based micro-texturing apparatus and method employ flexure bearing houses for rotatably supporting opposite ends of each of a first (e.g. upper) roll and a second (e.g. lower) roll to provide a working roll gap between the rolls, wherein at least one of the rolls has one or more micro surface features to plastically deform a surface of a workpiece deformed by rolling action in the roll gap. An electrical current may be passed through the workpiece to assist micro deformation. A roll gap adjusting device is operably associated with the first and second flexure bearing houses for adjusting the roll gap dimension to the final depth of the micro surface features to be imparted to the surface of the workpiece by the rolling action. A sheet material or antifriction element (e.g. journal bearing or bushing) is produced having at least one surface that includes rolled-in micro surface depressions wherein depressions have a lateral dimension of about 1 μm to about 10 mm and a depth of about 1 μm to about 10 mm, typically a lateral dimension of about 1 μm to about 100 μm and a depth of about 1 μm to about 100 μm.

摘要： Novel systems and methods for an incremental forming process to manufacture a product are disclosed herein. The system and method generally involves continuously modifying the toolpath in real-time based upon the forming force of the forming tool compared to a predicted springback error established offline from a series of simplified simulations. The system and method disclosed herein are effective to form products with complex geometries and minimizes the costs and time requirements associated with prior art techniques.

摘要： Knitmorphs and methods of knitmophing include knitting one or more yarn materials into knitted structure having a first shape. A thermal load may then be applied to all or part of the knitted structure to deform the knitted structure into a second shape. The thermal load can be removed to return the knitted structure to the first shape or a hardening agent can be applied to lock the knitted structure in the second shape.
