Definitions
- the invention relates to a method for improving a production plan for producing a three-dimensional component from sheet metal
- the invention further relates to a computer program product for improving a production plan for producing a three-dimensional component from sheet metal.
- a component can be manufactured from sheet metal in various ways.
- the two-dimensional development of the component can differ. It follows that different edges of the component must be bent or welded.
- the different production methods differ in their costs.
- the object of the invention is to provide a method and a computer program product which improve an existing production plan. This enables the three-dimensional component to be produced more quickly and/or more cost-effectively.
- This object is achieved according to the invention by a method for improving a production plan for producing a three-dimensional component from sheet metal, the component being manufactured from the sheet metal according to the production plan by means of cutting and bending and/or welding, the production plan comprising a first two-dimensional construction plan , the first construction plan having an outer contour for cutting out the component from sheet metal, the first construction plan having at least one bending edge and optionally one or more weld seams, the first construction plan being divided into surfaces along bending edges and weld seams, wherein the surfaces are rearranged to form at least one second two-dimensional construction plan, with the three-dimensional component being able to be manufactured from the second construction plan, with the construction plans being evaluated according to the length of the outer contour, the length of the weld seams and/or the number of bends, with at least one second construction plan being used the improved crafting plan is created when the rating of the second blueprint is better than the rating of the first blueprint.
- the two-dimensional construction plan includes a two-dimensional development of the component.
- the unfolding describes the shape that is to be cut out of the sheet metal.
- the mold includes an outer contour and optionally recesses within the outer contour. The recesses can be produced, for example, by means of cutting or punching.
- the construction plan includes bending edges with bending directions and bending angles. If one or more welds are provided, the construction plan also indicates which edges of the sheet metal are to be welded. Bending edges are located within the outer contour, weld seams along two areas of the outer contour that are to be welded together.
- the production plan can also contain information about the material to be used and/or the sheet thickness.
- connection of the surfaces to one another is retained when arranging them into a second construction plan.
- the type of connection between the first construction plan and the second construction plan can differ.
- the rating of the blueprints provides a measure of the cost and/or manufacturing time of the component.
- the evaluation metrics can be adaptable by the user of the method. For example, the user may incur costs and/or time for performing a welding operation of a certain length, a cutting operation of a certain length, and/or a bending operation to pretend Furthermore, the evaluation metrics can depend on the material and/or the sheet thickness.
- the second construction plan is optionally combined with information from the first production plan that is not contained in the second construction plan.
- information can, for example, be information about the material to be used and/or the sheet thickness.
- a graph is preferably created from the first construction plan, with the corners of the graph representing the surfaces of the construction plan and the edges of the graph representing the connections between the surfaces, an edge in the graph being able to represent a weld seam, a bending edge, a material connection or a missing connection , wherein the connection represented is changed at least for a part of the edges of the graph in order to generate the second construction plan.
- Using the graph ensures in a very simple way that the connection of the surfaces is maintained when arranging the surfaces to form a second construction plan. Changing the representation of the edges in the graph can change the way the surfaces are connected.
- an edge in the graph can only represent a material connection between surfaces that lie in the same plane and adjoin one another. Faces that are adjacent but not on the same plane can be connected by a weld, a flex line, or a missing connection. Faces that are adjacent and coplanar can be joined by a material bond, a weld, or a missing bond.
- a rectangle of minimum area enclosing the outer contour is preferably determined for the construction plans in each case and the area of the rectangle is included in the evaluation of the respective construction plan.
- a measure of the material consumption is determined by determining the minimum enclosing rectangle.
- the ratio of the area of the enclosing Rectangle to the area of the sheet metal used, i.e. a measure of the waste, go into the evaluation of the respective construction plan.
- the first construction plan has at least one attachment point, the area in which the attachment point lies being an attachment area, stability paths between the attachment areas being determined for each construction plan, with a stability path beginning on an attachment area and ending on an attachment area , whereby a stability path connects surfaces via bending edges and/or weld seams and/or material connections, whereby a second construction plan is evaluated as a stable construction plan if all surfaces that are connected to a fastening surface in the first construction plan via a stability path are also connected in the second construction plan via a Stability path are connected to a mounting surface.
- the three-dimensional dimensional stability of the component is checked with the stability paths. Faces swept by a stability path will maintain their relative location to the other parts in the manufactured part.
- the stability paths can therefore be used to determine which areas in the first construction plan should be stable to one another. In the second construction plan, the stability paths can be used to check whether the same surfaces will be stable to one another.
- a mounting surface contains at least one mounting point and is therefore inherently stable. If there is an attachment point, it can be assumed that the attachment surface is attached to another stable one Component is attached and will therefore have a stable position. All other surfaces must be swept by a stability path to be stable.
- a stability path begins at a mounting surface and ends at a mounting surface. Since the fastening surfaces in the manufactured component cannot change their position relative to one another, the surfaces covered by the stability path will also retain their position relative to the fastening surfaces. The stability paths thus guarantee that surfaces that are not attachment surfaces have a stable position relative to the attachment surfaces. Surfaces that are not covered by a stability path in the first construction plan are not taken into account when assessing whether the component is stable, since they do not have a stable relative position to the fastening surfaces in the first construction plan.
- a stability path preferably crosses each bending edge or weld seam at most once. This constraint improves blueprint stability checking. That is, the stability path will not leave a surface through the same bend line or weld that it used to enter the surface. A stability path that enters and exits a surface through the same bend edge or weld is indicative of the surface.
- the stability path is preferably determined in the graph. Determining the stability path is particularly easy in the graph. It should be noted that edges in the graph that represent a missing connection must not be crossed by the stability path.
- the first construction plan has at least two attachment points, with the at least two attachment points lying in a first area, with the first area being divided into two attachment areas between the two attachment points.
- Fastening points can be recognized automatically, e.g. if there are holes of a predetermined size in the surface.
- the holes can be produced by cutting or punching.
- the material connection is preferably changed to a missing connection. Since mounting surfaces are inherently stable, this change does not affect the stability of the part.
- a weld seam is preferably changed into a bending edge or a material connection. Changing a weld to a bend edge occurs on faces that were supposed to be welded at an angle in the first blueprint. Changing a weld to a material joint occurs on surfaces that should be welded in a plane in the first blueprint.
- a material connection is preferably changed to a missing connection when the second construction plan is created. This is particularly preferred when a surface is divided into multiple surfaces, as there are multiple attachment points in the surface.
- the three-dimensional component is manufactured according to the improved manufacturing plan using one or more machine tools.
- Machine tools are machines that can perform one or more of the cutting, punching, bending and welding operations. In this way, the component is produced particularly inexpensively and/or quickly.
- the method is preferably carried out as a computer-implemented method.
- the invention also includes a computer program product for carrying out a method according to the invention.
- Instructions for carrying out a method according to the invention using a computer are preferably stored on a non-volatile computer-readable storage medium.
- FIG. 2 shows a two-dimensional development of the component from FIG. 1;
- FIG. 3 shows a subdivided two-dimensional development of the component from FIG. 1;
- FIG. 4 shows a first graph created from the development shown in FIG. 3;
- FIG. 5 shows a second graph created from the graph shown in FIG. 4;
- Figure 6 shows a second plot generated from the graph shown in Figure 5;
- FIG. 7 is a schematic view of a component made from the development shown in FIG. 6;
- FIG. 8 shows the first development from FIG. 2 with two stability paths
- FIG. 9 shows the second development from FIG. 6 with two stability paths
- FIG 10 shows the two developments from FIGS. 2 and 6 in comparison.
- FIG. 1 shows a schematic view of a three-dimensional component 1.
- the three-dimensional component 1 consists of four surfaces. In a first face 11 there are three holes 21 . In a second surface 12 are two elongated holes 22 included. A third surface 13 and a fourth surface 14 are used for the stability of the component. Bent edges 23 are provided between the first surface 11 and the second surface 12 and between the first surface 11 and the third surface 13 and the first surface H of the fourth surface 14 . Weld seams 24 are provided between the second surface 12 and the third surface 13 and between the second surface 12 and the fourth surface 14 .
- FIG. 2 shows a two-dimensional first development of the component from FIG. 1.
- the construction plan is divided into areas along bending edges 23 .
- the three holes 21 are recognized as attachment points and in the second surface 12 the two elongated holes 22 are recognized as attachment points.
- the weld seams 24 are provided between the surfaces.
- FIG. 3 shows a subdivided two-dimensional development of the component from FIG. There is a respective material connection between the resulting surfaces 11a, 11b, 11c. Likewise, the second surface 12 is subdivided between the elongated holes 22 in such a way that each resulting surface 12a, 12b contains only one attachment point 21. There is a respective material connection between the resulting surfaces 12a, 12b. The resulting five surfaces 11a, 11b, 11c, 12a, 12b are attachment surfaces.
- FIG. 4 shows a first graph 4 created from the development 2 shown in FIG. 3.
- the nodes of the graph 4 represent the surfaces of the component 1.
- the edges of the graph 4 represent the connections between the surfaces.
- the first surface 11 was divided into three fastening surfaces 11a, 11b, 11c, so that a material connection 25 is represented between each of these fastening surfaces 11a, 11b, 11c.
- the second surface 12 was divided into two fastening surfaces 12a, 12b, so that a material connection 25 is represented between each of these fastening surfaces.
- the further edges of the graph 4 represent the corresponding bending edges
- Second construction plans are generated from the graph of the first construction plan 1 shown in FIG. 4 by changing the types of connections represented. Typically, bent edges are cheaper and quicker to produce than welds, so welds are preferably changed to bent edges. Material connections between mounting surfaces can often be replaced by missing connections.
- FIG. 5 shows a second graph 4 created from the graph shown in FIG. 4.
- the two weld seams 24 have been replaced by bending edges 23.
- the bending edges 23 between the first surface 11 and the second surface 12 have been replaced by missing connections 26.
- the material connection 25 between the two fastening surfaces 12a, 12b created from the second surface 12 has been replaced by a missing connection 26.
- FIG. 6 shows a second development 2 created from the second graph 4 shown in FIG. 5.
- the first development shown in FIG are each connected to the third surface 13 and the fourth surface 14 via bending edges 23 .
- a comparison of the developments 2 from FIG. 2 and FIG. 6 shows that the development 2 from FIG.
- Each parameter is preferably evaluated individually, with the weighting of the parameters being adjustable. The sum of the individual ratings gives the Evaluation of the construction plan.
- the evaluation of the second development and thus of the second construction plan from FIG. 6 is therefore better than the evaluation of the first development from FIG. 2.
- An improved production plan is therefore created based on the second development 2. With this manufacturing plan, the three-dimensional component can be manufactured faster and more cost-effectively using one or more machine tools than with the original manufacturing plan.
- FIG. 7 shows a schematic view of a component produced from the development shown in FIG.
- the second surface 12 is divided into two fastening surfaces 12a, 12b. There is no connection between the two mounting surfaces. Likewise, there is no connection between the parts of the second surface 12 and the first surface 11. Between the third surface 13 and the second surface 12 and between the fourth surface 14 and the second surface 12 there are bending edges instead of weld seams.
- Figure 8 shows the first development from Figure 2 with two stability paths 30.
- a first stability path 30 leads from the first surface 11 via a bending edge 23 to the third surface 13 and via a weld seam 24 to the second surface 12.
- a second stability path 30 leads from the first surface 11 via a bending edge 23 to the fourth surface 14 and via a weld seam 24 to the second surface 12.
- the stability paths 30 thus meet the condition that they each begin and end on a fastening surface.
- the stability paths 30 also meet the condition that each bending edge 23 or weld seam 24 is crossed at most once. Since all surfaces are covered by a stability path, the entire component is rated as stable.
- the stability paths 30 guarantee that all swept surfaces 13, 14 maintain a stable position relative to the mounting surfaces 11, 12.
- Figure 9 shows the second development from Figure 6 with two stability paths 30.
- a first stability path 30 leads from the first surface 11 via a bending edge 23 to the third surface 13 and via a further bending edge 23 to a fastening surface 12a of the second surface 12.
- a second Stability path 30 leads from the first surface 11 via a bending edge 23 to the fourth surface 14 and via a further bending edge 23 to the other attachment surface 12b of the second surface 12.
- These stability paths 30 also meet the conditions described for FIG. 8, so that the entire component is rated as stable.
- the painted surfaces 13, 14 will also maintain a stable position relative to the fastening surfaces 11, 12 according to this construction plan.
- FIG. 10 shows the two developments from FIGS. 2 and 6 in comparison.
- the minimum rectangle 31 is shown for this.
- the minimum rectangle is an enclosing rectangle of minimum area. This means that the minimum rectangle encloses the development with minimum area.
- the area of the minimum rectangle 31 is used as a measure of the material consumption in the assessment of the respective building plan.
