Description

Technical Field

[0001] This application relates to the field of machining technology, and particularly to an automatic part layout method, system, computer device, and medium. Background Art

[0002] In the field of machining such as automobile manufacturing and die manufacturing, it is often necessary to perform CNC (Computer Numerical Control Machine Tool) machining on various parts. These enterprises usually face the problem of part layout. Especially when producing large quantities or complex parts, the layout efficiency and quality directly affect the production efficiency and cost.

[0003] When performing part layout, operators mainly rely on personal experience and intuition to determine the position and orientation of parts on the machining plane. Due to different experiences and habits of each person, the layout results often lack unified standards and rules, resulting in chaotic layout. For example, the spacing between parts is inconsistent, or the orientation of parts is random. Operators need to repeatedly adjust the position and orientation of each part to ensure their reasonable distribution on the machining plane. And during the manual layout process, it is difficult to rearrange the positions of parts according to the existing shape and size of the leftover material, resulting in low utilization rate of the leftover material. For complex parts or large batch orders, this manual layout method is very inefficient, causing material waste and unable to meet production requirements, which will affect the subsequent machining efficiency and quality.

[0058] In the field of machining such as automotive manufacturing and die manufacturing, CNC machining of various parts is often required. These enterprises usually face the problem of part layout. Especially when producing large quantities or complex parts, the efficiency and quality of layout directly affect production efficiency and cost.

[0059] When arranging parts, operators mainly rely on personal experience and intuition to determine the position and orientation of parts on the machining plane. Due to different experiences and habits of each person, the layout results often lack unified standards and rules, leading to chaotic layout. For example, the spacing between parts is inconsistent, or the orientation of parts is random. Operators need to repeatedly adjust the position and orientation of each part to ensure their reasonable distribution on the machining plane. And during manual layout, it is very difficult to rearrange the positions of parts according to the existing shape and size of the remaining material, resulting in a low utilization rate of the remaining material. For complex parts or large-volume orders, this manual layout method is very inefficient, causing material waste and unable to meet production requirements, which will affect subsequent machining efficiency and quality.

[0060] To solve the above problems, this embodiment provides an automatic part layout method, system, computer device, and medium. First, obtain the part dimensions, part quantities, and processing requirements of the parts to be laid out, so as to determine the technical requirements, tolerance requirements, etc. of the parts to be processed through the processing requirements. Then, compare the part dimensions, part quantities, and processing requirements with the preset waste material layout conditions to screen out the first part set that meets the waste material layout conditions and the second part set that does not meet the waste material layout conditions, facilitating subsequent processing of different types of parts. For the first part to be laid out in the first part set, this application embodiment directly layouts all the first parts to be laid out through the preset waste material blank plate, thereby improving the utilization rate of waste material layout and avoiding material waste; for the second part to be laid out in the second part set, that is, the part that does not require waste material layout, this application embodiment determines the target layout rule according to the part shape of the second part to be laid out and layouts the second part to be laid out based on the target layout rule, thereby being able to meet various types of layout requirements, adapt to various layout functions, further meet various production requirements, and improve the processing efficiency and processing quality.

[0061] Please refer to Figure 1 , Figure 1 is the flowchart of the specific method of the automatic part layout method provided by this application embodiment. In some embodiments, the method includes but is not limited to steps S101 to S104.

[0062] Step S101, obtain the part dimensions, part quantities, and processing requirements of the parts to be laid out.

[0063] In step S101 of some embodiments, this application embodiment obtains the part dimensions, part quantities, and processing requirements of all the parts to be laid out, facilitating subsequent selection of a suitable method for automatic layout based on the different dimensions and requirements of the parts.

[0064] It should be noted that the processing requirements in this application embodiment include but are not limited to the technical requirements, tolerance requirements, etc. for processing the parts to be laid out, and this application embodiment does not make specific limitations.

[0065] Step S102, compare the part dimensions, part quantities, and processing requirements with the preset waste material layout conditions, and screen out the first part set that meets the waste material layout conditions and the second part set that does not meet the waste material layout conditions.

[0066] In step S102 of some embodiments, the part dimensions, the number of parts, and the processing requirements are compared with the preset leftover material layout conditions to screen out different types of part sets. Specifically, a first part set that meets the leftover material layout conditions and a second part set that does not meet the leftover material layout conditions are screened out, facilitating subsequent selection of corresponding layout rules for different types of parts to meet various types of layout requirements.

[0067] It should be noted that the leftover material layout conditions in the embodiments of the present application can be set by the user according to their needs. For example, the leftover material layout conditions are that the part dimensions are between 120mm * 80mm * 10mm and 140mm * 100mm * 20mm, the number of parts is between 4 and 8, and the processing requirement is a thickness tolerance of +0.02 - 0.05mm, etc. The embodiments of the present application do not make specific limitations.

[0068] Step S103: For the first parts to be laid out in the first part set, all the first parts to be laid out are laid out using the preset leftover material blank plate.

[0069] In step S103 of some embodiments, for the first parts to be laid out in the first part set, that is, the parts that need to be laid out using leftover materials, in the embodiments of the present application, all the first parts to be laid out are laid out using the preset leftover material blank plate, which can ensure that the layout of the first parts to be laid out on the leftover material blank plate is more compact, improve the utilization rate of leftover materials, and avoid waste of leftover materials.

[0070] It should be noted that the leftover material blank plate in the embodiments of the present application refers to a blank plate with a certain allowance reserved.

[0071] Step S104: For the second parts to be laid out in the second part set, determine the target layout rule according to the part shape of the second parts to be laid out, and lay out the second parts to be laid out based on the target layout rule.

[0072] In step S104 of some embodiments, for the second parts to be laid out in the second part set, that is, the parts that do not need to be laid out using leftover materials, in the embodiments of the present application, determine the target layout rule according to the part shape of the second parts to be laid out, so as to be able to determine the layout rules corresponding to different types of parts, and lay out the second parts to be laid out based on the target layout rule, realizing multi-type layout of parts, thus being able to meet various types of layout requirements and adapt to various layout functions.

[0073] Please refer to Figure 2 , Figure 2 is the specific flowchart of laying out all the first parts to be laid out using the preset leftover material blank plate provided by the embodiments of the present application. In some embodiments, the method includes but is not limited to steps S201 to S203.

[0074] Step S201, set the first dimension of the surplus blank plate according to the processing requirements of the first parts to be typeset, and set the first part spacing according to the first part dimensions and the first part quantities of all the first parts to be typeset.

[0075] Step S202, perform a typesetting test on all the first parts to be typeset according to the first dimension, the first part spacing, and the first part quantities.

[0076] Step S203, when all the first parts to be typeset pass the typesetting test, typeset all the first parts to be typeset on the surplus blank plate according to the first dimension and the first part spacing.

[0077] In steps S201 to S203 of some embodiments, during the process of typesetting all the first parts to be typeset by using a preset surplus blank plate, in this application embodiment, first set the first dimension of the surplus blank plate according to the processing requirements of the first parts to be typeset, where the first dimension includes the X-axis dimension and the Y-axis dimension of the surplus blank plate, so as to realize the rational utilization of the surplus blank plate, avoid material waste, and set the first part spacing according to the first part dimensions and the first part quantities of all the first parts to be typeset, so as to improve the space utilization rate of the surplus blank plate, ensure that the first parts to be typeset can be rationally typeset on the surplus blank plate, and avoid the situation that the parts are too compact or too loose. Then, perform a typesetting test on all the first parts to be typeset according to the first dimension, the first part spacing, and the first part quantities, so as to verify whether all the first parts to be typeset can be rationally typeset on the surplus blank plate, avoid typesetting errors or surplus waste, and further improve the surplus utilization rate. When all the first parts to be typeset pass the typesetting test, it means that all the first parts to be typeset can be rationally typeset on the surplus blank plate, and all the first parts to be typeset can be typeset on the surplus blank plate according to the first dimension and the first part spacing, which can ensure that the layout of the first parts to be typeset on the surplus blank plate is more compact, improve the surplus utilization rate, and avoid the situation of surplus waste.

[0078] It should be noted that the first part spacing in this application embodiment is the interval distance between adjacent first parts to be typeset.

[0079] It can be understood that in the embodiment of the present application, the part size of the first part to be typeset is 120mm * 80mm * 10mm, the thickness tolerance is +0.02 - 0.05mm, and the number of parts is 4 as an example for illustration. If the first part to be typeset has thickness tolerance requirements, in order to prevent deformation after processing and not meeting the tolerance requirements, the embodiment of the present application selects a blank plate with a thickness of 12mm. If the typesetting spacing is 11mm, the typesetting blank size is 360 * 130 * 12mm; if the first part to be typeset has no tolerance requirements, a blank plate with a thickness of 10mm can be selected, and the typesetting size is 360 * 130 * 10mm.

[0080] Please refer to Figure 3 , Figure 3 which is a specific flowchart of the part automatic typesetting method provided by another embodiment of the present application. The method includes but is not limited to steps S301 to step S302.

[0081] It should be noted that steps S301 to step S302 occur after typesetting tests are performed on all the first parts to be typeset according to the first size, the first part spacing, and the first number of parts.

[0082] Step S301, when any one of the first parts to be typeset fails the typesetting test, set the second size of the surplus blank plate according to the processing requirements of the first part to be typeset, and set the second part spacing according to the first part size and the first number of parts.

[0083] Step S302, perform typesetting tests on all the first parts to be typeset according to the second size, the second part spacing, and the first number of parts until all the first parts to be typeset pass the typesetting test.

[0084] In steps S301 to S302 of some embodiments, after typesetting and testing all the first parts to be typeset according to the first size, the first part spacing, and the first number of parts, there may be a situation where the space of the leftover blank plate is insufficient, that is, there is a situation where some of the first parts to be typeset are not successfully displayed on the leftover blank plate. For example, only a part of the first part to be typeset can be displayed on the leftover blank plate or it cannot be displayed at all. When any one of the first parts to be typeset fails the typesetting test, for example, there is a situation where a part of the first part to be typeset is incomplete on the leftover blank plate, at this time, set the second size of the leftover blank plate according to the processing requirements of the first part to be typeset, that is, reset the sizes of the X-axis and Y-axis of the leftover blank plate, and set the second part spacing according to the first part size and the first number of parts, that is, reset the spacing distance between two adjacent first parts to be typeset. Then, typeset and test all the first parts to be typeset according to the second size, the second part spacing, and the first number of parts, that is, verify again whether the size of the current leftover blank plate can meet the typesetting requirements of all the first parts to be typeset until all the first parts to be typeset can pass the typesetting test, ensuring a more reasonable layout of the parts on the material, thereby improving the utilization rate of the leftover materials and avoiding the waste of leftover materials.

[0085] Please refer to Figure 4 , Figure 4 which is a specific flowchart for determining the target typesetting rule according to the part shape of the second part to be typeset provided by the embodiments of the present application. The method includes but is not limited to steps S401 to S407.

[0086] Step S401: Compare the part shape of the second part to be typeset with the preset standard sheet metal shape.

[0087] Step S402: When the part shape of the second part to be typeset meets the preset standard sheet metal shape, determine the array typesetting rule as the target typesetting rule.

[0088] Step S403: When the part shape of the second part to be typeset does not meet the preset standard sheet metal shape, compare the part shape of the second part to be typeset with the preset non-standard sheet metal shape.

[0089] Step S404: When the part shape of the second part to be typeset meets the non-standard sheet metal shape, determine the alignment typesetting rule as the target typesetting rule.

[0090] Step S405: When the part shape of the second part to be typeset does not meet the non-standard sheet metal shape, compare the part shape of the second part to be typeset with the preset irregular sheet metal shape.

[0091] Step S406: When the part shape of the second part to be typeset meets the shape of an irregular sheet metal, determine the position typesetting rule as the target typesetting rule.

[0092] Step S407: When the part shape of the second part to be typeset does not meet the shape of an irregular sheet metal, determine the free typesetting rule as the target typesetting rule.

[0093] In steps S401 to S407 of some embodiments, in the process of determining the target typesetting rule according to the part shape of the second part to be typeset, the embodiments of the present application first compare the part shape of the second part to be typeset with a preset standard sheet metal shape. When the part shape of the second part to be typeset meets the preset standard sheet metal shape, it indicates that the second part to be typeset at this time is a standard part with a regular shape, and the array typesetting rule can be directly determined as the target typesetting rule to realize the selection of the array typesetting rule, which is convenient for subsequent typesetting directly through the array typesetting rule. When the part shape of the second part to be typeset does not meet the preset standard sheet metal shape, it indicates that the part shape of the second part to be typeset at this time may be a special case. For example, there is a notch or a protrusion in the second part to be typeset, etc. At this time, the part shape of the second part to be typeset is compared with a preset non-standard sheet metal shape to determine whether the part shape of the second part to be typeset meets other standard requirements. When the part shape of the second part to be typeset meets the non-standard sheet metal shape, the alignment typesetting rule can be directly determined as the target typesetting rule, which can reduce the path change in the processing process and reduce the number of rotations and recalibrations of the part during the processing. When the part shape of the second part to be typeset does not meet the non-standard sheet metal shape, it indicates that the part shape of the second part to be typeset may be an unconventional shape, that is, a strange shape. For example, the second part to be typeset is a pentagram shape, a wedge shape, etc. At this time, the part shape of the second part to be typeset is compared with a preset irregular sheet metal shape. When the part shape of the second part to be typeset meets the irregular sheet metal shape, the position typesetting rule is determined as the target typesetting rule, which can ensure the position accuracy during the typesetting process and ensure that the parts are aligned with each other. When the part shape of the second part to be typeset does not meet the irregular sheet metal shape, the free typesetting rule can be most directly determined as the target typesetting rule, that is, the second part to be typeset is freely and simply typeset to improve the typesetting efficiency. In the embodiments of the present application, the second part to be typeset is respectively compared with different typesetting conditions to determine the corresponding typesetting rule, realizing multi-type typesetting of the parts, so as to meet various types of typesetting requirements and adapt to various typesetting functions.

[0094] It should be noted that the shape of the standard sheet material in the embodiments of the present application can be set according to the needs of the user. For example, the shape of the standard sheet material is a standard sheet material that is square, a standard material that is a perfect circle, etc. The shape of the non-standard sheet material can be set according to the needs of the user. For example, the shape of the non-standard sheet material has notches, bosses, etc. around the part. The shape of the irregular sheet material can be set according to the needs of the user, and the embodiments of the present application do not make specific restrictions.

[0095] In some embodiments, when the target layout rule is the free layout rule, the embodiments of the present application first set the sixth part spacing according to the second part sizes and the second part quantities of all the second parts to be laid out, and then perform automatic layout according to the sixth part spacing, thereby improving the layout efficiency.

[0096] Please refer to Figure 5 , Figure 5 which is a specific flowchart for laying out the second parts to be laid out based on the target layout rule provided by the embodiments of the present application. The method includes but is not limited to steps S501 to step S502.

[0097] Step S501, when the target layout rule is the array layout rule, set the third part spacing and the arrangement quantity according to the second part sizes and the second part quantities of all the second parts to be laid out.

[0098] Step S502, perform array layout on the second parts to be laid out according to the third part spacing and the arrangement quantity.

[0099] In steps S501 to S502 of some embodiments, during the process of laying out the second parts to be laid out based on the target layout rule, when the target layout rule is the array layout rule, at this time, set the third part spacing and the arrangement quantity according to the second part sizes and the second part quantities of all the second parts to be laid out, where the arrangement quantity is the number of parts laid out on the X-axis and the number of parts laid out on the Y-axis, to avoid the situation that the distance between parts is too large or too small during the layout process, and at the same time avoid the situation that there are too many or too few parts in the X-axis or Y-axis direction during the layout process, and then perform array layout on the second parts to be laid out according to the third part spacing and the arrangement quantity, so as to achieve reasonable layout of the second parts to be laid out with standard and regular shapes and improve the layout efficiency.

[0100] Please refer to Figure 6 , Figure 6 which is a specific flowchart for laying out the second parts to be laid out based on the target layout rule provided by another embodiment of the present application. In some embodiments, it includes but is not limited to steps S601 to S603.

[0101] Step S601, when the target layout rule is the alignment layout rule, set the fourth part spacing according to the second part sizes and the second part quantities of all the second parts to be layouted.

[0102] Step S602, select an alignment reference part and a part to be moved from the second parts to be layouted, and set the alignment direction and the alignment angle.

[0103] Step S603, control the part to be moved to move based on the alignment reference part according to the fourth part spacing, the alignment direction, and the alignment angle.

[0104] In steps S601 to S603 of some embodiments, when the target layout rule is the alignment layout rule, at this time, set the fourth part spacing according to the second part sizes and the second part quantities of all the second parts to be layouted, that is, the spacing distance between adjacent second parts to be layouted, to avoid the spacing distance between adjacent parts being too far or too close. After that, select an alignment reference part and a part to be moved from the second parts to be layouted, where the alignment reference part is the part used as a reference, and the part to be moved is the part that needs to be moved, and set the alignment direction and the alignment angle. Among them, the alignment direction includes the directions of the X-axis, Y-axis, and Z-axis, and the alignment angle is the offset angle during the movement of the part. Then, according to the fourth part spacing, the alignment direction, and the alignment angle, control the part to be moved to move based on the alignment reference part, that is, align and move the part to be moved with reference to the alignment reference part, so as to achieve the alignment between the second parts to be layouted, improve the layout efficiency and neatness, and facilitate the subsequent unified processing of parts that meet the shape of non-standard sheet materials.

[0105] It can be understood that aligning the parts for layout can simplify the machining path of the tool, reduce the moving distance and direction change of the tool, and thus improve the machining efficiency. For example, if the notches or bosses of the parts are aligned, the tool can machine along a straight line or a simple curved path instead of frequently changing directions.

[0106] Please refer to Figure 7 , Figure 7 which is the specific flowchart of the automatic part layout method provided by another embodiment of the present application. The method includes but is not limited to steps S701 to S703.

[0107] Step S701, when the target layout rule is the position layout rule, set the fifth part spacing according to the second part sizes and the second part quantities of all the second parts to be layouted.

[0108] Step S702, select a position reference part and a part to be adjusted from the second parts to be layouted, and determine the reference plane of the position reference part.

[0109] Step S703: Control the part to be adjusted to perform position adjustment with the reference plane as the reference according to the fifth part spacing.

[0110] In steps S701 to S703 of some embodiments, when the target layout rule is the position layout rule, set the fifth part spacing according to the second part sizes and the second part quantities of all the second parts to be laid out, that is, the spacing distance between adjacent second parts to be laid out, to avoid the spacing distance between adjacent parts being too far or too close. Then, select a position reference part and a part to be adjusted from the second parts to be laid out, and determine the reference plane of the position reference part. Here, the position reference part is the part used as a reference, and the part to be adjusted is the part that needs to perform position adjustment. Then, determine the reference plane of the position reference part, and then control the part to be adjusted to perform position adjustment with the reference plane as the reference according to the fifth part spacing. Through reasonable position layout, the stability and consistency of the parts during the processing can be ensured, and the dimensional errors and shape deformations caused by clamping and processing errors can be reduced.

The re-layout module is configured to, when any one of the first parts to be laid out fails the layout test, set the second size of the leftover material blank plate according to the processing requirements of the first part to be laid out, and set the second part spacing according to the first part sizes and the first part quantities; and perform a layout test on all the first parts to be laid out according to the second size, the second part spacing, and the first part quantities until all the first parts to be laid out pass the layout test.
