Definitions
- FIG. 1 shows some examples of reconfigurable pin tooling.
- Incremental sheet forming does not use a die at all, but instead supports a sheet metal workpiece at the periphery and uses a programmed tool path to form a general 3-D sheet shape by the incremental motion of the tool.

- English wheel forming is typically a manual process that uses the controlled back and forth linear motion of a sheet between two rollers to cause it to reduce in thickness and extend normal to the rolling direction to produce singly or doubly curved surfaces, such as automobile fenders.

- FIG. 10 shows an exemplary computing environment in which example embodiments and aspects may be implemented.
- FIG. 4 is an illustration of a very simple and reconfigurable forming system 100 that can be low-cost, light weight and easily placed in austere environments.
- the system 100 includes a controller 120 and some number of (usually 1, 2 or 3) sets of stands 105 (i.e., the stands 105A, 105B, and 105C). In some embodiments, the stands 105 are nominally aligned along a line, instead of a 2-D array.
- the controller 120 may be implemented by one or more general purpose computing devices such as the computing device 1000 illustrated with respect to FIG. 10
- each stand 105 may include a plurality of pins 106 (i.e., the pins 106A, 106B, 106C, 106D, and 106E). More or fewer pins 106 may be included in each stand 105.
- the extension of each pin 106 is adjustable, ideally in an automated and computer-controlled manner by the controller 120.
- the sheet metal 150 which lies in the x-y plane would be pulled back and forth in the x direction. With each pass through the system 100 some or all of the pins 105 may be advanced in the z direction to begin approximating the shape of the desired component.
- FIG. 5 shows a concept for one stand 105 of this system 100.
- a series of pins 106 i.e., the pins 106A-106GG
- the end of each pin 106 has a low friction rounded end or roller. Low friction is desired at the pin 106 ends. This can be accomplished with lubrication, rollers, and standard means such as ultrasonic vibration may also reduce friction.
- the sheet metal 150 lies in the x-y plane and is pulled through the pins 106 in the X direction.
- the pins 106 may start at the first pass where they all are placed along a line. With each pass the shapes can be developed. The focus could be on producing only one feature (such as one bend in a multi-bend configuration, such as the in the flower diagram in FIG. 3C, or the whole component could be developed at once).
- a turret of rollers could also be used to allow easy change of the roller types.
- a piece of sheet metal 150 is introduced to the array of points when both the sheet 150 and point 106 ends are nearly linearly arrayed in the y direction.
- the sheet 150 will typically be much longer in the x-direction than y and is moved (usually pulled) through the pin array in the x-direction from one end to the next.
- the pins 106 are moved in a programmed way to cause the sheet to deform gradually and incrementally to take on the shape of the pin 106 array, which usually becomes increasingly complex with increased z displacements.
- the pins 106 can be advanced manually via simple methods such as screw threads, and this process may be automated by the controller 120 using stepper motors, for example.
- FIGS. 6A and 6B show how a single primary bend can be created either by pins 106 or rollers 121.
- FIG. 6A shows an embodiment using pins 106 (i.e., the pins 106A, 106B, and 106C).
- FIG. 6B shows an embodiment using rollers 121 (i.e., the rollers 121A and 121B).
- the sheet 150 is processed repeatedly by motion in the x-direction with an increase in the bend depth d after each pass. Dimensional measurements after each pass (allowing for relaxation by springback) can be used to program the next pass or determine when sufficient deformation is developed. Use of this repeated primary mode of deformation may be sufficient, used in a repeated way to develop many of the wide variety of components that are available by roll forming.
- FIGS 6A and 6B will generally produce a relatively sharp corner, depending on factors such as the strain hardening ability of the sheet 150.
- Radiused rollers 121 can also be used to control the radius of curvature, but a larger tool set is required. If a constant radius of curvature is desired, an incremental 4-pin system can be used such as that shown in FIG. 7. This will produce a nominally constant radius of curvature over the bent region that is set by the displacement of the pins 106 and the properties of the sheet metal 150.
- FIG. 8 shows a stand 105A and a stand 105B that may be adjacent to one another in a system 100.
- the stand 105B is offset from the stand 105A by 90°.
- the stand 105C is generated by combining the stands 105A and 105B.
- twisting is often a problem, and this is combatted by opposed twisting force between roll stands 105. This can be treated by using two pin 106 arrays with a relative twist between them to cancel out any twist developed in asymmetric forming. Also, this could be used to impart twist that is a design objective.
- This invention of forming metal 150 by repeatedly moving a sheet through a stand 105 of pins 106 that progress with each pass is lightweight, can be low-cost, will have increasing utility as control systems become more sophisticated and can process material relatively quickly with relatively little power and energy.

Description
LINEAR PASS INCREMENTAL SHEET METAL FORMING
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to US Provisional Patent Application Serial No. 63/481,839, filed on January 27, 2023, and titled "LINEAR PASS INCREMENTAL SHEET METAL FORMING," the contents of which are hereby incorporated by reference in their entireties.
GOVERNMENT SUPPORT CLAUSE
[0002] This invention was made with government support under project number 2133630 awarded by the National Science Foundation. The government has certain rights in the invention.
BACKGROUND
[0003] Many structural components have what can be referred to as an extruded geometric configuration. That is the part has some shape in the x-y plane that is replicated down the z-axis. I-beams are a simple example of this. These shapes are ubiquitous for structural designs because they can have high section stiffness and the relatively complex shapes allow for useful features, such as interlocks or slides.
[0004] There are two classical methods of creating such shapes from structural materials, one is extrusion, where material is bulk formed through a die to create a shape with many degrees of freedom on the cross section. The other is roll-forming which is widely used for many architectural, automotive, appliance, furniture, and other applications. These components usually have a cross section that is of nominally constant thickness and is made by a rather continuous incremental bending process by the application of many roll passes.
[0005] Reconfigurable pin tooling uses the concepts of 3-D pin art to create a die surface based on the motion of several pins in a 2-D array. This allows the creation of dies for sheet metal forming, die-casting, injection molding and other forming or molding methods. This method has been developed in many sub-variants and has seen commercial use and has been reviewed in some depth. FIG. 1 shows some examples of reconfigurable pin tooling. [0006] Incremental sheet forming does not use a die at all, but instead supports a sheet metal workpiece at the periphery and uses a programmed tool path to form a general 3-D sheet shape by the incremental motion of the tool. Tools may be used on one side or both to form the shape. This has seen significant commercial application in recent years.
[0007] English wheel forming is typically a manual process that uses the controlled back and forth linear motion of a sheet between two rollers to cause it to reduce in thickness and extend normal to the rolling direction to produce singly or doubly curved surfaces, such as automobile fenders. It is a well-established process that is not practiced automated commercial ways to any large extent. FIG. 2 is an illustration of the mechanics of the English wheel forming process.
[0008] Roll Forming is described briefly and schematically in FIG. 3, and is a widely used commercial technology. Part A of FIG 3. is an illustration of typical roll forming equipment. Part B is an illustration of stripped-down view of individual roll stations. Part C is an illustration of three sequences of typical "flower diagrams" where each roll operation (each operation from top to bottom) places a bend or radius in the part, to make the eventual shape.
[0009] Roll forming is a high-productivity process, in that many hundreds of pounds of materials can be processed per hour with roll-forming systems, but they rely on many machined rolls that are used in a coordinated fashion. As a result, to move from one
product to another new dies must be designed, installed, and used.

DETAILED DESCRIPTION
[0031] In the following description, specific details are set forth describing some embodiments consistent with the present disclosure. Numerous specific details are set forth in order to provide a thorough understanding of the embodiments. It will be apparent, however, to one skilled in the art that some embodiments may be practiced without some or all of these specific details. The specific embodiments disclosed herein are meant to be illustrative but not limiting. One skilled in the art may realize other elements that, although not specifically described here, are within the scope and the spirit of this disclosure. In addition, to avoid unnecessary repetition, one or more features shown and described in association with one embodiment may be incorporated into other embodiments unless specifically described otherwise or if the one or more features would make an embodiment non-functional. In some instances, well known methods, procedures, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.
[0032] FIG. 4 is an illustration of a very simple and reconfigurable forming system 100 that can be low-cost, light weight and easily placed in austere environments. The system 100 includes a controller 120 and some number of (usually 1, 2 or 3) sets of stands 105 (i.e., the stands 105A, 105B, and 105C). In some embodiments, the stands 105 are nominally aligned along a line, instead of a 2-D array. The controller 120 may be implemented by one
or more general purpose computing devices such as the computing device 1000 illustrated with respect to FIG. 10
[0033] As shown by the stand 105C, each stand 105 may include a plurality of pins 106 (i.e., the pins 106A, 106B, 106C, 106D, and 106E). More or fewer pins 106 may be included in each stand 105. The extension of each pin 106 is adjustable, ideally in an automated and computer-controlled manner by the controller 120.
[0034] The sheet metal 150, which lies in the x-y plane would be pulled back and forth in the x direction. With each pass through the system 100 some or all of the pins 105 may be advanced in the z direction to begin approximating the shape of the desired component.
[0035] FIG. 5 shows a concept for one stand 105 of this system 100. Here we see a series of pins 106(i.e., the pins 106A-106GG) attached to a main support, all of which are adjustable in the z direction (and may be staggered in x to allow better adjustable engagement with the main support). The end of each pin 106 has a low friction rounded end or roller. Low friction is desired at the pin 106 ends. This can be accomplished with lubrication, rollers, and standard means such as ultrasonic vibration may also reduce friction. The sheet metal 150 lies in the x-y plane and is pulled through the pins 106 in the X direction. The pins 106 may start at the first pass where they all are placed along a line. With each pass the shapes can be developed. The focus could be on producing only one feature (such as one bend in a multi-bend configuration, such as the in the flower diagram in FIG. 3C, or the whole component could be developed at once).
[0036] A turret of rollers could also be used to allow easy change of the roller types. A piece of sheet metal 150 is introduced to the array of points when both the sheet 150 and point 106 ends are nearly linearly arrayed in the y direction. The sheet 150 will typically be much longer in the x-direction than y and is moved (usually pulled) through the pin array in
the x-direction from one end to the next. The pins 106 are moved in a programmed way to cause the sheet to deform gradually and incrementally to take on the shape of the pin 106 array, which usually becomes increasingly complex with increased z displacements. The pins 106 can be advanced manually via simple methods such as screw threads, and this process may be automated by the controller 120 using stepper motors, for example.
[0037] There are multiple strategies that can be used to move from one shape to the next. Examples are shown in the Flower diagram of FIG. 3C. As the main mode of deformation is bending, rather than intended thickness reduction, and small deformation per pass is anticipated, the pulling and z-direction forces on the press stand can be relatively small and are reduced by reduced pin displacement from one pass to the next. Higher productivity is developed with larger per-pass deformation.
[0038] FIGS. 6A and 6B show how a single primary bend can be created either by pins 106 or rollers 121. FIG. 6A shows an embodiment using pins 106 (i.e., the pins 106A, 106B, and 106C). FIG. 6B shows an embodiment using rollers 121 (i.e., the rollers 121A and 121B). The sheet 150 is processed repeatedly by motion in the x-direction with an increase in the bend depth d after each pass. Dimensional measurements after each pass (allowing for relaxation by springback) can be used to program the next pass or determine when sufficient deformation is developed. Use of this repeated primary mode of deformation may be sufficient, used in a repeated way to develop many of the wide variety of components that are available by roll forming.
[0039] The system in FIGS 6A and 6B will generally produce a relatively sharp corner, depending on factors such as the strain hardening ability of the sheet 150. Radiused rollers 121 can also be used to control the radius of curvature, but a larger tool set is required. If a constant radius of curvature is desired, an incremental 4-pin system can be used such as
that shown in FIG. 7. This will produce a nominally constant radius of curvature over the bent region that is set by the displacement of the pins 106 and the properties of the sheet metal 150.
[0040] Often closed, or nearly closed, sections are desired in a sheet 150 from roll forming operations. These typically require force in the y-direction in addition to the z- direction. There are numerous ways to use this approach to make sections of this type. The simplest way is to re-orient the part (e.g., sheet 150) by a 90° rotation, or a second die set could be used to do this simultaneously in two pin stands 105 that are adjacent to one another. This approach is shown in FIG. 8. The approach can be generalized to provide forces in varied directions relative to the part. This will allow the setting of corners, for example.
[0041] FIG. 8 shows a stand 105A and a stand 105B that may be adjacent to one another in a system 100. The stand 105B is offset from the stand 105A by 90°. The stand 105C is generated by combining the stands 105A and 105B.
[0042] There are several observations from roll forming that can be easily adapted here. First, for asymmetric parts, twisting is often a problem, and this is combatted by opposed twisting force between roll stands 105. This can be treated by using two pin 106 arrays with a relative twist between them to cancel out any twist developed in asymmetric forming. Also, this could be used to impart twist that is a design objective.
[0043] Programmed curvature or bends along the long direction of the part (or development of straight sections in asymmetric components) can be accomplished using three separate and sequential pin 106 array stands 105 and the relative position of these can be used to curve the component about the y or z directions, similar operations are common post roll-forming procedures with 3-roller arrays.
[0044] In all these cases, a dimensional feedback system, such as a camera, coordinate measuring or other dimensional measurements can be used to feedback the current state and this can be used to control cross section, twist, bend and so forth. Control or physical stops are often required to assure that the deformation action is along the proper line in the sheet 150. This is usually along a fixed y coordinate, but in advanced applications, this may vary systematically.
[0045] One important practical consideration is the development of systems that are sufficiently stiff and strong. Traditional engineering design of the pins 106 and supports can accomplish this, finding the optimal combination of mass and performance. Also, tongue and groove contacts between the pin segments is possible to give more lateral stiffness to the pin 106 sections.
[0046] What is described here are the relatively simple applications of this 2-D pin array with repeated sheet 150 motion. There are obvious finishing steps. All the common postprocessing steps in roll forming are possible including piercing, shearing, and using rollers to emboss or develop texture. Further, it is possible to move the pins while the workpiece is in motion. This takes the current approach beyond what can be done with roll forming. This will allow for the fabrication of much more complex shapes where the cross section varies along the x direction.
[0047] This invention of forming metal 150 by repeatedly moving a sheet through a stand 105 of pins 106 that progress with each pass is lightweight, can be low-cost, will have increasing utility as control systems become more sophisticated and can process material relatively quickly with relatively little power and energy. Accordingly, it has several places where it may be of considerable use:
[0048] In space manufacturing, low earth orbit, lunar or deep space this can be used to
create arbitrarily long columns from rolls of metal that are easy to store. Without gravity it becomes very simple to move the columns from end to end without support. Metal coils are efficient from a volume point of view, and this requires little energy to process and shape can be varied along the x direction for attachment points, etc.
[0049] In traditional terrestrial manufacturing, this system is well suited for rapid local manufacturing as only incoming metal is needed. This can speed development of many projects.
[0050] FIG. 9 is an illustration of a method 900 for iteratively deforming a sheet of metal. The method 900 may be implemented by the system 100, for example.
[0051] At 910, a desired design is received. The desired design may be received by the controller 120 of the system 100. The desired design may be an object or other structure that a user or administrator has selected for the system 100 to apply to a sheet of metal 150. For example, the desired design may be panel of certain dimension and thickness that the user or administrator would like to create from the sheet of metal 150. Other designs may be used.
[0052] The system 100 may include the controller 120 and a plurality of stands 105. Each stand 106 may include a plurality of pins 106 that are selectively moved (e.g., extended or retracted) to cause the sheet of metal 150 to be selectively deformed as it moves through the system 100. As will be described further below, the system 100 may repeatedly process the sheet of metal 150 using different pin 106 configurations until the sheet of metal 150 conforms to the desired design.
[0053] At 920, the sheet of metal is received. The sheet of metal 150 may be received by the system 100. The sheet of metal 150 may be a variety of metals including, but not limited to to, steel, aluminum, and titanium. Other types of metals may be used.
[0054] At 930, physical properties of the sheet of metal are determined. The properties may be determined by the controller 120 of the system 100 using a camera, for example. The properties of the sheet of metal 150 may include its overall dimensions, thickness, and any bends or curves that may be present in the sheet of metal 150. Other properties may be included. In some embodiments, determining the physical properties may include determining a shape of the sheet of metal.
[0055] At 940, the determined physical properties are compared to the desired design. The determined physical properties may be compared to the desired design by the controller 120. The controller 120 may then, based on the comparison, determine what changes to make to the sheet of metal 150 to better conform to the desired design.
[0056] At 950, at least some pins are adjusted. The controller 120 of the system 100 may adjust some of the pins 106 based on the determined changes that have to be made to the sheet of metal 150 to better conform to the desired design. In some embodiments, the controller 120 may determine the bends or deformations that should be made to conform to the desired design and may adjust at least some of the pins 106 so that at least some of the bends and or deformations are applied to the sheet of metal 150 when the sheet of metal 150 is passed through the system 100.
[0057] At 960, the sheet of metal is passed through the stands. The sheet of metal 150 may be passed through the stands 105 (including pins 106) of the system 100. Any method for moving the sheet of metal 150 through the system 100 may be used.
[0058] At 970, revised physical properties of the sheet of metal are determined. The revised properties may be determined by the controller 120 of the system 100 using the camera, for example. The properties of the sheet of metal 150 have changed due to the passing of the sheet of metal 150 through the pins 106 of the stands 105. The revised
physical properties may be a revised shape.
[0059] At 980, the determined revised physical properties are compared to the desired design. The determined revised physical properties may be compared to the desired design by the controller 120. The controller 120 may then, based on the comparison, determine what additional changes to make to the sheet of metal 150 to better conform to the desired design.
[0060] At 990, at least some pins are adjusted. The controller 120 of the system 100 may adjust some of the pins based on the determined additional changes that have to be made to the sheet of metal 150 to better conform to the desired design.
[0061] At 995, the sheet of metal is again passed through the stands. The sheet of metal 150 may be passed through the stands 105 (including pins 106) of the system 100. The method 900 may then continue at 970 and repeat steps 970-995 until it is determined that the sheet of metal 150 substantially conforms to the desired design.
