[0057] CNC (Computer Numerical Control, CNC) technology, also known as computer numerical control technology, is a technology that uses computers to achieve digital program control. CNC equipment is equipment that uses CNC technology to achieve automated processing. With the development of computer technology, the application of CNC equipment is becoming more and more extensive.

[0058] At present, in the process of CNC equipment processing, it is necessary to use CNC machine tools to carry out quality inspection on products. Usually, the inspection file is copied to the hard disk of the CNC machine tool through a USB flash drive. The CNC machine tool reads the hard disk content and executes the inspection program to obtain the inspection result. Finally, the inspection result is copied to the analysis system through the USB flash drive for analysis to generate an inspection report. The manual data copying process is complicated and requires manual monitoring and processing, resulting in low inspection efficiency and increased error rate, which is not suitable for the current industry trend of intelligent manufacturing.

[0059] In order to solve the problems existing in the above-mentioned prior art, the embodiments of the present application provide an automated product detection system and detection method. In the present application, a plurality of point data of a product is generated by a point data generation system, and the point generation system sends the plurality of point data to an execution system. The execution system processes the point data to generate a program file executable by a CNC machine tool, and sends it to the control CNC machine tool to execute the program file. The execution system performs product detection and analysis based on the theoretical and actual deviation results generated after the execution of the CNC machine tool and generates a detection report. The above process realizes the refined management of the production process in a digital and automated manner. Every step from data collection to quality inspection depends on accurate data and an automated system. The above-mentioned automated detection method does not rely on manual participation, automatically completes the detection of processed products, and the detection process is simple, thereby improving the detection efficiency of products.

[0060] See also Figure 1 , is a flow chart of the detection method provided in the embodiment of the present application. As an example but not limitation, the method may include the following steps:

[0061] S101, obtaining a plurality of point data of a processed product, where the point data is coordinate information of a detection position of the processed product.

[0062] In the embodiment of the present application, obtaining multiple point data of the processed product refers to using various technical means to obtain the coordinate information (x, y, z, i, j, k) of a specific detection position on the processed product. These coordinate information are usually position data in three-dimensional space, which is crucial for manufacturing processes such as CNC machining. In modern manufacturing processes, in order to accurately control machine tools to process and detect parts, it is necessary to know the precise position of each processing target. This includes not only the coordinates of the detection starting point and / or end point, but also the position information (point data) of each point on the detection path.

[0063] Methods for obtaining point data may include:

[0064] Measurement: Use various measuring equipment, such as coordinate measuring machine (CMM), on-machine measurement, laser scanner, etc. to directly measure points on the part;

[0065] Modeling: Extract point data from CAD models. CAD software can generate mathematical models of parts, from which point information for testing can be extracted, or point data can be generated directly through the digital product development system (Next Generation, NX);

[0066] Calculation: Through complex mathematical algorithms and simulations, the point data of the machine tool movement is calculated. This is usually done in CAM software.

[0067] In one embodiment, see Figure 2 , is a schematic diagram of the process of obtaining point data provided by an embodiment of the present application, such as Figure 2 As shown, one implementation of step S101 includes:

[0068] S201, obtaining a processing model of a processed product;

[0069] In the embodiments of the present application, the processing model is a key concept, also referred to as a detection model or a 3D model, which generally refers to a digital model used to guide machine tool processing. This model contains all necessary information such as the geometric information of the part, the processing and / or detection path, the cutting parameters, etc., so that the machine tool can perform processing and detection according to predetermined requirements. In actual operation, obtaining the processing model of the processed product is accomplished by using professional CAM software. These software are usually compatible with specific machine tools and controllers, can generate accurate CNC programs, and realize efficient machine tool automation processing.

[0070] S202, generating a plurality of point data of the processed product according to the processing model.

[0071] In an embodiment of the present application, generating multiple point data of the processed product based on the processing model refers to converting the feature type and processing parameters defined in the CAM software into specific position coordinate information, which represents the position of each point that needs to be reached during the machine tool detection process.

[0072] In one embodiment, step S202 includes:

[0073] Acquire multiple detection positions of the processing model; acquire coordinate data of each of the multiple detection positions according to the multiple detection positions; and generate each set of point data of the processed product according to each set of coordinate data.

[0074] In the embodiment of the present application, when using the processing model point data, it is necessary to set the detection position to be detected in advance, and obtain multiple point data of the processed product according to the detection position, so as to detect the processed product using the multiple point data.

[0075] Exemplarily, CAM software can be used to obtain multiple point data of processed products. Specifically, it can be: obtain the detection position of the processing model: in the CAM software, it is first necessary to define the detection position of the processing model. These positions are usually key points on the processing path, such as the starting point, end point, inflection point, etc. of the cutting path. Multiple detection positions can be selected arbitrarily; obtain the coordinate data of the detection position: according to the defined detection position, the CAM software will calculate the precise coordinates of each position in the processing coordinate system. The acquisition of coordinate data is usually completed through the calculation function of the CAM software, which will combine the geometric information in the processing model with the parameters of the detection position to calculate the coordinates of each position; generate point data: organize the acquired coordinate data into a point data list. These data lists usually contain information such as the coordinates (x, y, z, i, j, k) of each detection position, tool number, processing parameters, etc., and the generation of point data can be realized through the data output function in the CAM software. The software will output the calculated coordinate data in a certain format to facilitate subsequent detection operations.

[0076] In the above method, the point data can provide accurate coordinate information, which can improve the detection accuracy of the detection method.

[0077] S102, generating a program file according to a plurality of point data.

[0078] In the embodiment of the present application, the program file is usually a text file in the field of CNC machining, which contains G codes and M codes for controlling CNC machine tools. These code instructions tell the machine tool how to move and what operations to perform. For example, G codes are used to control the movement and processing mode of the machine tool, while M codes are used to control the auxiliary functions of the machine tool, such as starting the coolant, shutting down the machine tool, etc.

[0079] In one embodiment, step S102 includes:

[0080] In an embodiment of the present application, a detection path for a processed product is generated based on a plurality of point data; a control language recognizable by a processing device is acquired; and a program file is generated from the detection path based on the control language.

[0081] In the embodiment of the present application, the point data generally includes the position information of each point on the product that needs to be detected. By processing the position information of these points, a detection path can be generated, that is, the path that the probe needs to move during the detection process. This includes determining the order of processing, cutting path, cutting depth, etc. In some cases, path optimization may also be required to improve detection efficiency and quality. The above detection path is used to control the processing equipment to detect the product.

[0082] Different processing equipment (such as CNC machine tools, wire cutting machines, milling machines, grinders, etc.) may use different control languages. The control language is a set of instructions used to tell the equipment how to perform specific operations. For example, CNC machine tools usually use G codes and M codes, which correspond to different motion control and function control commands. In this step, the instruction set needs to be prepared according to the control language of the processing equipment. Once the control language and detection path are determined, the next step is to convert the detection path into an instruction set that the execution equipment can understand, that is, to generate a program file. This process usually involves the use of CAM software, which can convert high-level processing and / or detection descriptions into low-level control instructions. The generated program file is usually a text file that contains all the instructions required by the equipment. This file can be directly read and executed by the processing equipment (CNC machine tool).

[0083] In another embodiment of the present application, the system generates a detection path for the processed product based on multiple point data, feature types, theoretical values, and starting positions; obtains a control language recognizable by the processing equipment; and generates a program file for the detection path based on the control language.

[0084] Specifically, the multiple point data can be P1, P2, P3, and P4, and the corresponding coordinate information is P1 (x1, y1, z1, i1, j1, k1), P2 (x2, y2, z2, i2, j2, k2), P3 (x3, y3, z3, i 3, j3, k3), and P4 (x4, y4, z4, i4, j4, k4). The feature type is circle, the theoretical value is 6 mm in diameter, and the starting position is P0 (x0, y0, z0, i 0, j0, k0). The system automatically generates a detection path for the processed product based on this information, and generates a program file for the detection path according to the control language recognizable by the processing equipment. The processing equipment executes the path program file, the probe jumps to the starting position P0, and performs the detection task according to the program, and generates a detection report for the processed product.

[0085] In the above method, the feature type can be circle, cylinder, hole, slot, etc., and the corresponding point data is also different. The point data can be adjusted according to actual needs. The theoretical value is the design reference value, and the starting position is the initial position of the processing equipment to detect this feature type, which can be adjusted according to actual needs.

[0086] In the above method, the detection requirements starting from the point data are converted into an instruction set that the execution device can understand, and finally a program file is generated. This file guides the execution device on how to complete the detection task accurately and efficiently. The automation of this process greatly improves the detection efficiency of the product.

[0087] S103, controlling the processing equipment to inspect the processed products according to the program file, and obtaining the theoretical and actual deviation values ​​corresponding to each point data.

[0088] In the embodiment of the present application, in CNC machining or similar precision manufacturing processes, the program file usually contains a series of instructions that tell the processing equipment (such as CNC machine tools) how to move and what operations to perform to process and / or detect the processed products. In the actual processing and / or detection process, due to various factors (such as machine tool accuracy, tool wear, material properties, etc.), the actual detection position may deviate from the expected detection position. These deviation values ​​are crucial to ensure product quality and accuracy.

[0089] Specifically, the processing equipment operates according to the instructions in the program file, including the probe to a specific point for detection. During the detection process, various measurement systems (such as photoelectric sensors, laser rangefinders, three-coordinate measuring machines, etc.) are usually used to monitor the detection position in real time. These systems will collect actual data of the current detection position.

[0090] The actual data collected needs to be compared with the theoretical position preset in the program file. This usually involves the following steps: compare the actual measured position data with the theoretical position data (point data), and calculate the deviation value of each point data, that is, the difference between the actual position and the theoretical position (theoretical and actual deviation values). The deviation value of each point data will be recorded and analyzed. This helps to identify potential problems in the processing process, such as machine tool errors, tool wear, etc., and allows the operator to make adjustments.

[0091] In one embodiment, the deviation values ​​corresponding to each point data can be directly read into the graph by UG through the TXT file, and the deviation values ​​corresponding to each point data can be directly displayed on the graph. For example, the deviation data of point A can be directly read into the graph by UG through the TXT file, and the deviation data of point A can be directly displayed on the corresponding point. The deviation value above the range is a color (such as red), the deviation value within the range is a color (such as green), and the deviation value below the range is a color (such as gray).

[0092] In the above method, obtaining the theoretical and actual deviation values ​​of the point data can provide data support for product documentation and traceability. When quality problems occur, it is possible to quickly locate the link where the problem occurred and take corresponding corrective measures.

[0093] S104, performing quality inspection on the processed product according to the theoretical and actual deviation values ​​corresponding to the plurality of point data to obtain the inspection result.

[0094] In the embodiment of the present application, step S104 may be implemented as follows:

[0095] The theoretical and actual deviation values ​​corresponding to each set of point data are compared with the preset error; if the theoretical and actual deviation values ​​corresponding to each set of point data are not greater than the preset error, the processed product is judged to be qualified; if there is at least one set of point data whose theoretical and actual deviation values ​​are greater than the preset error, the processed product is judged to be unqualified.

[0096] In the embodiment of the present application, the quality of the product is evaluated according to the deviation value and the pre-set quality standard. The smaller the deviation value, the higher the quality of the product. If the deviation value is within an acceptable range (preset error, generally ± 0.01 or ± 0.02), the product can be considered qualified. If the deviation value exceeds the quality standard, it is necessary to identify the problems that may cause the deviation. This may include machine tool accuracy problems, tool wear, material inhomogeneity, etc.

[0097] In the above method, by strictly comparing the theoretical and actual deviation values, it can be ensured that the processed products meet the precise quality requirements and meet the high-precision production standards.

[0098] In one embodiment, the method further comprises:

[0099] A test report of the processed product is generated based on the test results of the quality test on the processed product; and permissions are allocated to access users based on the test report so that the users who have obtained permissions can view the test report.

[0100] In the embodiment of the present application, after the processing of the product is completed, a series of quality inspections will be carried out, including dimensional measurement, performance testing, etc. The inspection results will be recorded and organized into a report format, usually including product information, inspection methods, results, deviation analysis, etc. The report may be in paper form or in an electronic document, such as PDF or a report in a specific quality management software.

[0101] It should be noted that test reports may contain sensitive information, such as product defects, problems in the production process, etc. This information needs to be properly protected. Not all employees need to access all quality test reports, so permissions need to be assigned based on responsibilities and needs.

[0102] Depending on the content and importance of the test report, the system administrator or quality management personnel will define different access levels and permissions. Permission allocation may be based on factors such as the user's role, department, and position. For example, production line workers may only be able to view reports related to their work, while quality management personnel may have broader access rights. When users try to access test reports, the system will verify their permissions. If users do not have sufficient permissions, they will not be able to view the report or can only view part of the content. Users who have obtained permissions can access the test report through the interface of the quality management system, the electronic document management system, or other authorized channels. Users can analyze and process the report as needed, such as taking corrective measures and improving processes.

[0103] In the above method, permissions are assigned to access users based on the test report to ensure that only users with appropriate permissions can review and process the test report, thereby protecting the sensitivity of quality information and promoting timely resolution and continuous improvement of quality issues.

[0104] In one embodiment, see Figure 3 , is a schematic diagram of the detection system provided in the embodiment of the present application, see Figure 3 ,The detection system includes a service device and a control device;

[0105] A service device, used for acquiring multiple point data of the processed product and sending the multiple point data to the control device;

[0106] The control device is used to generate a program file according to the multiple point data after receiving the multiple point data sent by the service device;

[0107] The control device is also used to control the processing equipment to detect the processed products according to the program file, and obtain the theoretical and actual deviation values ​​corresponding to each point data;

[0108] The control device is also used to receive the theoretical and actual deviation values ​​corresponding to each point data generated after the processing equipment executes the program file;

[0109] The control device is also used to perform quality inspection on the processed product according to the theoretical and actual deviation values ​​corresponding to each point data after receiving the theoretical and actual deviation values ​​corresponding to each point data sent by the processing equipment to obtain the inspection result.

[0110] In the embodiment of the present application, the service device may be a digital product development system (Next Generation, NX), which is a comprehensive software platform that integrates computer-aided design (CAD), computer-aided engineering (CAE), computer-aided manufacturing (CAM) and other tools. The NX system is used to generate a 3D model (also called a processing model or a detection model) of a processed product, and arbitrarily select point data of multiple detection positions according to the 3D model (also called a processing model or a detection model).

[0111] The control device can be a manufacturing execution system (MES). The MES system is connected to the NX system and the processing equipment respectively. The MES system is a production management and control system at the workshop level, which is responsible for monitoring, controlling and optimizing the entire manufacturing process from raw materials to finished products. The MES system ensures the efficiency, transparency and traceability of the production process through functions such as real-time data acquisition, production scheduling, quality control, and equipment management. The MES system is used to obtain multiple point data sent by the NX system, and generate program files based on multiple point data and send the program files to the machine tool (processing equipment) to drive the machine tool to execute the program files. After the machine tool executes the program files, the test results (theoretical and actual deviation values) are generated. Since the machine tool communicates with the MES system, the MES system collects the test results and analyzes them, generates a test report, and assigns permissions to the test report so that personnel with designated permissions can review the test report on the MES system.
