Definitions
- the invention relates to a computer-implemented nesting method for generating a nesting plan by nesting workpiece parts with different two-dimensional workpiece part geometries on a workpiece panel with a two-dimensional workpiece panel geometry, wherein the nesting plan can be used for a laser cutting method for cutting out the workpiece parts nested according to the nesting plan from the workpiece panel placed on a workpiece support.
- a cutting method in which workpiece parts are cut out of a workpiece panel is preceded by nesting methods, for example using exact or heuristic methods are known from the prior art.
- Nesting refers to an allocation or placement of the workpiece parts to be cut on the workpiece board for the subsequent laser cutting process.
- the workpiece parts to be cut out are assigned unique positions on the workpiece board or their workpiece board geometry with their workpiece part geometry.
- This allocation or allocation which is referred to herein as nesting of the workpiece parts on the workpiece board, is saved in the nesting plan.
- the nesting plan can be called up in the laser cutting process and by tracing the cutting edges with a laser according to the contours of the workpiece parts on the workpiece board, the workpiece board can be cut in order to obtain the individual workpiece parts.
- the purpose of the nesting process is to create a nesting plan by means of which it is possible to use the workpiece board as efficiently as possible so that as little waste as possible is generated.
- One challenge with the nesting process is that during laser cutting, a lot of laser energy is emitted towards the workpiece support with the workpiece panel resting on it, since only part of the laser energy is absorbed by the material of the workpiece panel to be cut.
- the workpiece support is therefore typically considered a wearing part that must be replaced frequently.
- Such a workpiece support typically consists of vertical support strips that support the parts on evenly distributed tips.
- a problem with Such workpiece supports in turn have the disadvantage that the cut-out workpiece parts can tend to tip over, which creates a risk of collision between the tilted workpiece part and the laser cutting head used for the laser cutting process.
- One way of minimizing this risk is to use a uniform minimum workpiece part distance between two adjacent workpiece parts in the nesting plan, which can be selected in particular depending on the radius of the laser cutting head or its nozzle, so that a currently cut and tilted workpiece part can be passed without collision when the next workpiece part is cut.
- a workpiece part-spanning or uniform and conservative workpiece part distance of, for example, 15 mm between workpiece parts is therefore selected.
- the invention is based on the object of proposing a nesting method with which particularly efficient nesting plans can be generated. The object is achieved by a computer-implemented nesting method according to claim 1.
- a computer-implemented nesting method for generating a nesting plan by nesting workpiece parts with, in particular, different, two-dimensional workpiece part geometries on a workpiece panel with a two-dimensional workpiece panel geometry, wherein the nesting plan can be used for a laser cutting process for cutting out the workpiece parts nested according to the nesting plan from the workpiece panel placed on a workpiece support, in particular on a support grid, and wherein the nesting process has the following process steps: (a) reading in geometry data of the workpiece parts, (b) determining individual geometry characteristics of at least some of the workpiece parts from their geometry data, (c) determining individual workpiece distances between adjacent workpiece parts on the workpiece panel based on their individual geometry characteristics, and (d) nesting the workpiece parts with their individual workpiece distances on the workpiece panel.
- the nesting process according to the invention enables a significantly more efficient use of the workpiece panel by nesting with individual workpiece distances instead of a conservative, uniform workpiece distance. Because of the individual workpiece spacing, smaller workpiece spacings can be selected between at least some or all of the workpiece parts, so that space or area on the workpiece board is saved, which in turn can be used to arrange or nest further workpiece parts on it. In this way, the material of the workpiece board is reduced by the residual skeleton remaining after cutting, or the waste is reduced. Such increased material efficiency through closer nesting of the workpiece parts can be achieved according to the invention, as described in more detail below. is achieved with the same high level of process reliability with regard to the laser cutting process.
- the individual workpiece distances are not chosen randomly.
- the individual workpiece distances are determined based on geometry data that is read in beforehand. For this purpose, individual geometry characteristics of some or all workpiece parts that are nested on the workpiece board are determined from the read-in geometry data. This makes it possible to use the geometries of the individual workpiece parts as a basis for determining the workpiece distances and thus to select individual workpiece distances depending on the geometry. Individual means in particular that an individual workpiece distance is selected for each workpiece part. This does not mean that all workpiece distances must be different from neighboring workpiece parts.
- the individual workpiece distances can be freely selected or come from a group of at least two or more defined workpiece distances in order to speed up the nesting process.
- the individual workpiece distances can be determined, for example, using an algorithm, artificial intelligence, a look-up table, etc.
- the nesting process can generate a nesting plan for the first time or can be based on an already generated one.
- Nesting plan can be applied so that it is partially re-nested (in process step (d)).
- the nesting problem of efficiently nesting workpiece parts on a workpiece board can basically be divided into three sub-problems. Firstly, it can be determined which workpiece part should be placed or nested on which workpiece board.
- the nesting method according to the invention can, if required, implement various of the known methods for efficient nesting. In the present case, however, the only mandatory requirement with regard to nesting is that the individual workpiece spacings are used for nesting the workpiece parts. In other words, the nesting method according to the invention can of course implement other methods which, in addition to the individual workpiece spacing, specify the position, orientation, etc. of the individual workpiece parts on the workpiece board in order to allow efficient nesting.
- method step (b) is carried out for at least some of the workpiece parts to be nested means that it is also possible to determine the workpiece spacing for at least one or more workpiece parts using a different method, for example by means of a fixed workpiece spacing. Nevertheless, it can of course be provided that individual workpiece spacings are determined for all of the workpiece parts to be nested on the workpiece board in order to carry out the nesting. In addition, method steps (a) to (d) are carried out in the order given. In particular, it can be provided that the individual geometry characteristics are determined by comparing the read-in geometry data with at least one predetermined geometry parameter. The advantage of this is that the geometry data is evaluated in a defined manner in order to obtain the individual geometry characteristics from it.
- the at least one geometry parameter is specified in such a way that it is indicative of a process risk of the laser cutting process.
- the process risk includes a process stability of the laser cutting process, a tipping probability of the workpiece parts on the workpiece support, a collision probability of the workpiece parts with a cutting head used in the laser cutting process and/or a fall probability for the workpiece parts to fall through the workpiece support, in particular the support grid.
- a small individual workpiece spacing can be determined. This can ensure that large workpiece spacings are only used on the workpiece board or in the nesting plan where there is a process risk, in particular of a type defined by the above process risk parameters. Where, however, the process risk is low, the workpiece spacing can be kept to a minimum or even disappear completely. However, a certain minimum workpiece spacing is typically desired for high cutting quality, so that a minimum workpiece spacing is preferably maintained in the nesting plan, even if individual workpiece spacings are determined.
- the individual geometry characteristics can each indicate a value for at least one of the aforementioned process risk parameters of process stability, tipping probability, collision probability and fall probability.
- the at least one geometry parameter is at least one of the following geometry parameters: a support surface, a center of gravity and an extension along at least one coordinate in a two-dimensional coordinate system.
- the aforementioned geometry parameters have a decisive influence on relevant process risk parameters in the laser cutting process, in particular on the aforementioned process parameters of process stability, tipping probability, collision probability and fall probability. For example, it can be decisive whether the support surface of a workpiece part typically rests on more or fewer than three support pins of the workpiece support. It can also be decisive whether a workpiece part typically rests on two support pins of the workpiece support along the two coordinates or axes of the two-dimensional coordinate system. These factors and, for example, the center of gravity of the workpiece part, as geometry parameters, determine the process risk for a workpiece part, in particular its tipping and collision probability.
- the workpiece support comprises support areas which are formed in particular by support webs and/or support pins.
- the support pins can be arranged on the support webs, wherein the support webs are arranged parallel to one another.
- the expected position can include information about which support areas, for example support pins, of the workpiece support the workpiece parts rest on and this information is taken into account when determining the individual workpiece distances.
- the expected position can be determined, for example, by appropriate sensors and/or cameras on the corresponding processing machine.
- at least one cutting parameter of the laser cutting process, a machine parameter of a processing machine for processing the workpiece panel and/or a material parameter of the workpiece panel is taken into account when determining the individual workpiece distances.
- the cutting parameter can in particular be a gas pressure and/or a cutting gap width.
- the material parameter can be, for example, a material thickness and/or a material weight, in particular a specific weight per volume.
- a process risk of the laser cutting process can be specified in a separate process step and included when determining the individual workpiece distances. In this way, a level of material efficiency and process reliability of the nesting process, which are the objectives of the Nesting process, the workpiece parts that are at least partially opposite one another can be specified in each case by determining the individual workpiece distances accordingly.
- the workpiece parts are classified into at least two geometry classes based on their geometry data and that individual geometry characteristics are only determined for those workpiece parts that fall into a predefined one of the two geometry classes.
- One of the at least two geometry classes can be selected in such a way that workpiece parts that have a (minimum) process risk are classified into this geometry class. This allows a pre-selection of workpiece parts based on their process risk. If, for example, workpiece parts can be seen from their geometry data to typically rest very stably on the workpiece support, for example because they are very large and rest on many support points on the workpiece support, the process risk of these workpiece parts tipping over and colliding with the cutting head is very low.
- a predefined minimum workpiece distance can be selected for each of these workpiece parts, which can be a minimum value for a desired cutting quality.
- workpiece parts that are very small and would therefore fall through the workpiece support and therefore cannot collide with the cutting head can be classified into another geometry class.
- Such workpiece parts are typically nested in such a way that they remain on the residual skeleton after laser cutting with microjoints. For these workpiece parts, too, it is not necessary to carry out the entire nesting process with steps (a) to (d).
- the nesting process can concentrate on the critical workpiece parts through intelligent preselection. This is because the individual geometric characteristics are only determined for those workpiece parts that fall into the predefined geometry class for which there is a process risk. Furthermore, it can be provided that the nesting process also includes the process step of determining individual workpiece orientations on the workpiece table for at least some of the workpiece parts based on their individual geometric characteristics. Now, the determined individual workpiece orientation can be used to determine whether the process risk of a workpiece part can be reduced by reorientation, particularly if the relative position of the workpiece part on the support areas of the workpiece support is known.
- the object mentioned at the outset is further achieved by a computer program product according to claim 13.
- the computer program product comprises instructions which, when the program is executed by a computer, cause the nesting method according to the invention to be carried out.
- the computer program product can, for example, be a computer program code per se or a product which contains the computer program, for example a data carrier or a data memory.
- the object mentioned at the outset is also achieved by a processing method according to claim 14.
- the processing method is set up for processing a workpiece panel, the processing method comprising: - the nesting method according to the invention for generating a nesting plan for a nesting of workpiece parts with different two-dimensional workpiece part geometries on a workpiece panel with a two-dimensional workpiece panel geometry, and - a laser cutting method for cutting out the workpiece parts nested according to the nesting plan from the workpiece panel, in particular by means of a laser cutting beam emerging from a cutting head, wherein, in order to cut out the workpiece parts, the laser cutting beam is used to trace cutting contours of the workpiece part geometries of the workpiece parts nested according to the nesting plan on the workpiece panel.
- the system is designed for machining a workpiece panel, the system comprising: - a computer for executing the nesting method of the machining method according to the invention, and - a laser cutting device for carrying out the laser cutting method of the (inventive) processing method.
- the computer which can be designed in particular as a control unit or as part of the control unit, can also be used to control the cutting device.
- the computer can have the computer program product according to the invention.
- the computer and the laser cutting device can be spatially offset from one another or spatially close to one another. They can be connected to one another, for example, by wireless or wired communication or at least be set up for such a communication connection.
- the computer can be in a remote cloud and wirelessly send the generated nesting plan to the laser cutting device, in particular a processing machine with the laser cutting device.
- the processing machine can generate the nesting plan locally with the computer.
- the system can in particular have a processing machine, wherein the laser cutting device can be part of the processing machine.
- Such a processing machine can of course also have other components that are necessary or beneficial for the processing process, such as a workpiece support, a workpiece part collecting device, a (linear) robot for moving the cutting head, etc.
- the System can be formed in particular by the processing machine. Additional features described herein with respect to the nesting method apply equally with respect to the computer program product, the processing method and the system, and vice versa.

- a workpiece panel 40 to be cut (as raw or starting material) can be placed and stored on a pallet 38 and introduced into the housing of the laser cutting device 20 for the laser cutting process.
- the pallet 38 can be moved out of the laser cutting device 20 with a processed workpiece panel 40, as shown in Fig. 1, so that workpiece parts 44 cut according to the nesting plan 46 can be sorted from the remaining workpiece of the workpiece panel 40 and removed from the processing machine.
- Figure 2 shows a laser cutting process 300 in the laser cutting device 20.
- a cutting head 24, which is controlled by the computer 50 and emits the laser cutting beam 1 for cutting out the workpiece parts 44 from the workpiece panel 40 onto the workpiece panel 40, can be freely positioned in the cutting area so that the laser cutting beam 1 can be guided essentially along any two-dimensional cutting contours 42 over the workpiece panel 40 to be cut.
- a cutting contour 42 for the laser cutting beam 1 is specified in the computer 50 based on the nesting plan 46 in order to cut out the workpiece parts 44 from the workpiece panel 40.
- the computer 50 is shown here as an example as a fixed part of the processing machine, but can alternatively be connected wirelessly to the processing machine and thus form the system 10.
- a computer 50 beyond the computer 50 shown can also be used for Nesting can be used.
- the nesting plan 46 indicates the arrangement of the individual workpiece parts 44 on the workpiece panel 40, as can be seen in Fig. 1.
- the nesting plan 46 can include the specification of piercing points and predetermined cuts for piercing the laser cutting beam 1 and guiding the laser cutting beam 1 along the cuts to the cutting contour 42 (not shown).
- the laser cutting beam 1 heats the metal of the workpiece panel 40 along the predetermined cutting contours 42 until it melts.
- a cutting gas jet in particular made of nitrogen and/or oxygen, can emerge from the cutting head 24 in the area of the laser cutting beam 1 and press the molten material of the workpiece panel 40 downwards and out of the gap that is formed.
