[0036] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only the parts related to the present application, rather than all structures, are shown in the accompanying drawings.

[0037] Figure 1 A flow chart of the electrode program design method provided in the embodiment of the present application is provided. The present embodiment is applicable to the case where the electrode program is designed before machine tool processing. The method can be executed by an electrode program design device, which can be implemented in the form of hardware and / or software and integrated in an electronic device that executes the method. Preferably, the electronic device in the embodiment of the present application can be a server, or a computer device, etc.

[0038] refer to Figure 1The electrode programming method of this embodiment includes but is not limited to the following steps:

[0039] S110 , loading a target model file, and determining parameter information of a target workpiece from the target model file.

[0040] The target model file is an electronic file related to the production target workpiece. The current electronic file may record a three-dimensional structure diagram or a two-dimensional structure diagram of the target workpiece, and the parameter information required for the production of the target workpiece is marked in the three-dimensional structure diagram or the two-dimensional structure diagram. Optionally, the target model file may also include a front view, a top view, and a side view of the target workpiece, so as to facilitate the analysis of the structure of the target workpiece from different angles, which is helpful to improve the production accuracy of the target workpiece in subsequent production.

[0041] The application scenario of this solution can be that after executing the solution provided by this embodiment on the client side to generate the electrode processing file of the target workpiece in the subsequent step S140, the electrode processing file can be packaged and sent to the manufacturer, and the manufacturer imports the electrode processing file into the operating system of the processing machine tool, so that the operating system automatically loads the electrode processing program in the electrode processing file to realize automated production. This process does not require the machine tool operator to manually set the processing parameters in the operating system of the processing machine tool, reduces the operator's operating steps, and improves the accuracy of workpiece production.

[0042] Generally, the file format of the target model file is related to the implementation software of the drawing model file. When designing an electrode program, it can be implemented on the application software of the client's electronic device. Then, the method of loading the target model file on the current application software can be to export the target model file into a format that the current application software can recognize, so that after loading the target model file on the current application software, the parameter information of the target workpiece can be obtained; or an application programming interface (Application Programming Interface, referred to as API) can be provided for the implementation software corresponding to the target model file in the current application software, so that the parameter information of the target workpiece can be obtained on the current application software through interface calls. The specific method of loading the target model file is not limited here.

[0043] In this embodiment, the parameter information includes at least shape parameters, structure parameters, size parameters and process parameters.

[0044] Among them, shape parameters are used to determine the composition structure of the target workpiece, such as round, square, spherical; complex structures such as curved surfaces, grooves or protrusions can also be determined; structural parameters are used to determine the components in the target workpiece, and the matching relationship, constraints, and assembly sequence between the components can be obtained through structural parameters. For example, the position, quantity and specifications of bolt connections, the size and shape of welding parts, etc., can also be used through the explosion view function to more clearly observe the structure of the assembly and determine the relative position and spatial relationship of each component; size parameters are used to determine the production specifications of the target workpiece, such as the length, width, height, diameter, radius, angle, dimensional tolerance and other parameters of the target workpiece; process parameters are used to determine the attribute information and precision information of the target workpiece, such as workpiece material, processing technology, surface treatment and roughness.

[0045] S120, determining the number of electrodes of the processing electrodes, and dividing the target workpiece into at least one processing area according to the number of electrodes.

[0046] Machining electrodes are tools used in machining machine tools to process workpieces. In actual production, due to the differences in specifications, complexity and production processes of various workpieces, the number of machining electrodes required to produce the target workpiece varies to a certain extent.

[0047] When determining the number of electrodes for machining, the complexity of the structure can be determined based on the shape parameters and structural parameters. For example, the workpiece can be analyzed to determine the number of electrodes based on the complexity of the structure, such as grooves of different depths, complex curved surfaces, small holes, etc., so that different parts can be machined separately using electrodes of different shapes to ensure machining accuracy and efficiency. The number of electrodes can also be determined based on the accuracy requirements, so that areas of different accuracy can be machined using the corresponding electrode processing methods, such as rough machining, semi-finishing and finishing.

[0048] A preferred embodiment, in order to improve the accuracy of the number of electrodes required for processing different workpieces, this embodiment determines the number of electrodes for processing electrodes through an algorithm optimization method, specifically: determining constraints based on processing cost and processing time, and constructing an objective function based on processing efficiency and processing accuracy; solving the objective function under the constraints, and when the objective function reaches the maximum value, determining the number of electrodes based on the processing cost.

[0049] In this embodiment, the increase in the number of electrodes will increase the processing cost and processing time, but it may also improve the processing efficiency and accuracy. This solution comprehensively considers multiple important factors such as processing cost, processing time, processing efficiency and processing accuracy, and can more comprehensively evaluate the rationality of the number of electrodes, while ensuring the processing quality, and minimize the number of electrodes. Then, under the condition of the lowest processing cost, the algorithm model further outputs the number of electrodes for the processing electrodes based on the shape parameters and structural parameters of the workpiece.

[0050] After determining the number of electrodes, the target workpiece needs to be further divided into at least one processing area according to the current number of electrodes to clarify which processing area of ​​the workpiece corresponding to each electrode needs to be processed in subsequent production.

[0051] The method of dividing the target workpiece into at least one processing area according to the number of electrodes is to divide it according to production experience, or to divide it according to production complexity. The specific method of dividing at least one processing area according to the number of electrodes is not limited here.

[0052] In another preferred embodiment, the method of dividing the target workpiece into at least one processing area according to the number of electrodes in the present scheme is: the precision information of the target workpiece determines the processing allowance; while meeting the demand for processing allowance, the target workpiece is divided according to the shape parameters, structural parameters and number of electrodes of the target workpiece to obtain at least one processing area.

[0053] The precision information of the target workpiece can be understood as the tolerance requirement of the workpiece size in the target model file. The smaller the tolerance, the higher the dimensional accuracy requirement. For example, for some precision mold parts, the dimensional tolerance may be required to be within ±0.01mm.

[0054] Machining allowance refers to the thickness or volume of a part of the material that is left on the basis of the size of the part blank in order to ensure the size, shape, position accuracy and surface quality of the workpiece after machining. In this embodiment, the machining allowance is obtained by comprehensively determining various machining errors. Among them, various machining errors may include discharge machining error, electrode loss error and machine tool accuracy error. The machining allowance is set to be greater than the sum of various machining errors to ensure that the size of the workpiece after production is within the tolerance range.

[0055] Among them, the discharge machining error refers to the existence of a discharge gap in the machining process of the machining machine, which will cause a difference between the actual machining size and the electrode size. According to experience and machine tool parameters, the size of the discharge gap is estimated to be between a few microns and tens of microns; the electrode loss error refers to the gradual loss of the machining electrode during the machining process, especially when machining for a long time or machining materials with higher hardness, the electrode loss will affect the accuracy of the machining size, and a certain margin needs to be reserved to compensate for the electrode loss; the machine tool accuracy error refers to the accuracy of the machine tool itself. It will also affect the machining size. Understand the accuracy indicators of the machine tool, such as positioning accuracy, repeated positioning accuracy, etc.

[0056] Optionally, when determining the machining allowance based on the precision information of the target workpiece, on the basis of considering the influence of discharge machining error, electrode loss error and machine tool precision error on the machining allowance, the influence of machining time and number of machining times on the machining allowance can also be considered. Generally, the longer the machining time, the greater the electrode loss. If the machining time of the workpiece is long, more machining allowance needs to be reserved to compensate for the electrode loss. For workpieces that need to be processed multiple times, each machining will cause certain loss to the electrode. Taking into account the cumulative loss of multiple machinings, the allowance for each machining is reasonably set. The specific method of determining the machining allowance in this embodiment is not limited here.

[0057] Finally, when dividing the target workpiece, on the basis of reserving the machining allowances of each target workpiece, the shape diversity corresponding to the shape parameters of the target workpiece and the structural complexity corresponding to the structural parameters are analyzed, so as to divide the target workpiece according to the determined number of electrodes, thereby dividing the corresponding machining area for each machining electrode. The target workpiece division scheme provided in this embodiment can meet the machining accuracy requirements and machining costs.

[0058] S130. For any processing electrode, determine the electrode shape according to the shape parameters and structural parameters corresponding to the processing area, and determine the electrode subroutine according to the size parameters and process parameters corresponding to the processing area.

[0059] The electrode shape affects the final processing of the target workpiece. For example, when the electrode shape closely matches the shape of the workpiece, effective discharge processing can be performed in various parts to achieve higher processing accuracy. On the contrary, if the electrode shape does not match the workpiece, it may cause uneven processing allowances, affecting dimensional accuracy and surface quality. The electrode shape determines the size of the discharge area. For large-area planar processing, using a larger-sized planar electrode can quickly remove material and improve processing efficiency. The electrode shape affects the movement mode during the processing. Reasonable selection of electrode shape and movement mode can improve processing efficiency. For target workpieces with complex shapes, it may be necessary to use multiple small-sized electrodes for combined processing to improve processing efficiency.

[0060] Another preferred embodiment, in this embodiment, the method of determining the electrode shape according to the shape parameters and structural parameters corresponding to the processing area is as follows: determine the initial electrode shape according to the shape parameters corresponding to the processing area; correct the initial electrode shape according to the structural parameters corresponding to the processing area to obtain the electrode shape corresponding to the processing area.

[0061] The shape characteristics of the target workpiece are analyzed according to the shape parameters and structural parameters corresponding to the processing area, and the initial electrode shape is determined according to the shape characteristics: for example, for plane processing, a plane electrode can be selected; for circular holes, a cylindrical electrode can be selected; for complex curved surfaces, a spherical electrode or a special-shaped electrode customized according to the curved surface shape can be selected. The structural complexity (such as whether the structures contain nesting or complex connections, etc.) is further determined according to the structural parameters, so that the specific workpiece shape can be customized based on the initial electrode shape, and complex workpiece contours can be accurately processed.

[0062] The purpose of determining the electrode subroutine in this embodiment is to control the machining electrode by loading the corresponding electrode subroutine for the machining electrode when the machining machine is actually working. That is, the process of setting the machining electrode parameters is implemented in the client electronic device, and there is no need for the machine tool operator to perform manual operation in the machining machine, thereby reducing the operating steps of the machine tool operator, avoiding the risk of incorrect parameter input, and improving the machining accuracy of the machine tool.

[0063] When determining the electrode subroutine of each machining electrode according to the size parameters and process parameters corresponding to the machining area, the size parameters affect the control trajectory of the machining electrode, and the process parameters affect the production accuracy of the machining electrode on the workpiece. Specifically, this embodiment can determine the electrode subroutine of each machining electrode through the following steps:

[0064] a) Determine the electrode material according to the workpiece material of the target workpiece.

[0065] Different workpiece materials have different conductivity, hardness and melting points, and different electrode materials will be selected when processing different workpiece materials. For example, for workpiece materials with good conductivity, such as copper, aluminum, etc., you can choose electrode materials with good conductivity, such as graphite, copper-tungsten alloy, etc.; while for workpiece materials with higher hardness, such as cemented carbide, stainless steel, etc., you may need to choose electrode materials with higher hardness, such as tungsten steel, molybdenum, etc. The melting point of the workpiece material will also affect the selection of electrode materials. If the melting point of the workpiece material is high, you need to choose an electrode material with a higher melting point to avoid the electrode material from melting too early during the processing and affecting the processing quality.

[0066] b) Determine electrode parameters according to process parameters and electrode materials corresponding to the processing area;

[0067] In this embodiment, the process parameters in this embodiment include at least surface roughness parameters, tolerance parameters and processing feature parameters, etc. Among them, the surface roughness parameters are used to indicate the smoothness of the surface of the target workpiece, which has an important impact on the appearance and performance of the product; the tolerance parameters include dimensional tolerance and form and position tolerance, dimensional tolerance is used to specify the allowable deviation range of the target workpiece size, and the size of the dimensional tolerance directly affects the processing accuracy and assembly performance of the target workpiece; form and position tolerance can include shape tolerance (such as flatness, roundness, etc.) and position tolerance (such as parallelism, verticality, etc.), and form and position tolerance is used to control the geometric shape and position accuracy of the product; processing feature parameters can include hole feature parameters (such as hole diameter, depth, position, etc.), groove feature parameters (such as groove width, depth, length, etc.), thread feature parameters (thread specifications (such as diameter, pitch, etc., precision grade, etc.) and surface feature parameters (for complex curved surface parts, it is necessary to provide the equation of the surface, control point coordinates, etc.).

[0068] The electrode parameters in this embodiment include discharge current, pulse width and pulse interval. When determining the electrode parameters according to the process parameters and electrode materials corresponding to the processing area, different electrode materials will affect the selection of discharge parameters of the electrode. For example, graphite electrodes are generally suitable for processing with larger currents and longer pulse widths; copper electrodes are suitable for processing with smaller currents and shorter pulse widths. Select parameters considering the requirements of the processing technology. For example, a larger discharge current and a longer pulse width can be selected during rough processing to improve processing efficiency; a smaller discharge current and a shorter pulse width should be selected during fine processing to improve processing accuracy and surface quality.

[0069] c) Determine the electrode movement trajectory according to the size parameters and process parameters corresponding to the processing area.

[0070] The size parameters (length, width, depth, etc.) of the processing area directly affect the movement path density and coverage of the processing electrode in the area. For example, for a small-sized groove processing area, the processing electrode may need to perform fine reciprocating motion in a narrow space to ensure sufficient removal of excess material.

[0071] Different surface quality requirements in further process parameters will affect the choice of electrode motion trajectory. For areas requiring high surface quality, the electrode movement should be smoother to avoid severe acceleration and impact. For example, when processing optical molds, the electrode can use slow curve movement to obtain a smooth and flawless surface.

[0072] d) Generate an electrode subroutine according to the electrode parameters and electrode motion trajectory corresponding to the machining electrode.

[0073] The current step may be implemented by writing the obtained electrode parameters corresponding to the machining electrode and the trajectory parameters corresponding to the electrode motion trajectory into a preset program framework, thereby generating an electrode subroutine for the current machining electrode.

[0074] Accordingly, the solution provided in this embodiment, after determining the electrode shape according to the shape parameters and structural parameters corresponding to the processing area, further includes: determining the shaking mode of each processing electrode according to the electrode shape. The electrode shape will affect the discharge uniformity, processing accuracy, and electrode strength and stability, so different electrode shapes need to select an appropriate shaking mode.

[0075] Generally speaking, for cylindrical electrodes, the common shaking methods are circular shaking and linear shaking; square electrodes usually use rectangular shaking or diagonal shaking; the shaking method of special-shaped electrodes needs to be determined according to their specific shapes. Generally speaking, the shaking of special-shaped electrodes needs to consider factors such as the contact area between the electrode and the workpiece, the distribution of the discharge points, and the processing accuracy requirements.

[0076] Then, the electrode subprogram is generated according to the electrode parameters and electrode motion trajectory corresponding to the processing electrode: the electrode subprogram is generated according to the electrode parameters, electrode motion trajectory and shaking mode corresponding to each processing electrode. The relevant information affecting the operation of the electrode is written into the corresponding electrode subprogram, reducing the manual operation of the subsequent operator on the processing machine tool.

[0077] Optionally, after the number of electrodes in the target workpiece, the divided processing areas, the electrode shape corresponding to each electrode, and the electrode subroutine corresponding to each electrode are designed, experimental simulation can be carried out in advance before actual processing to verify the rationality of the simulation of the electrode subroutine for processing the target workpiece based on the experimental model. If it is unreasonable, the optimal electrode parameters and electrode motion trajectory can be determined by adjusting parameters such as discharge current, pulse width, pulse interval, etc., and observing the processing effects such as processing speed, surface roughness, electrode loss, etc.

[0078] S140, generating an electrode processing file according to the electrode subroutine corresponding to each processing electrode, so that the processing machine tool can control the processing electrode set to the corresponding electrode shape through the electrode processing file, so as to obtain the target workpiece after the processing machine tool ends its operation.

[0079] In this embodiment, the electrode processing file includes not only the electrode subroutine corresponding to each processing electrode, but also the parameter file corresponding to each processing electrode, which helps the manufacturer to further verify the relevant parameters according to the electrode processing file.

[0080] Optionally, the electrode processing file may also include a program for the electrode shape corresponding to each processing electrode. The purpose of this is that, according to the actual processing technology, the electrode shape corresponding to each processing electrode needs to be processed in advance using a processing device (processing equipment, such as a CNC milling machine, an electric spark wire cutting machine, etc.), the electrode material is processed to produce the electrode shape, and then the electrode shape is installed on the processing machine, so that the processing operation of the component in the corresponding processing area is realized according to the corresponding electrode subroutine through the processing electrode set to the electrode shape.

[0081] The processing machine tool reads the transmitted electrode processing file, and each processing file may include a file identifier, so that when the processing machine tool parses the electrode processing file, it can verify whether it is an electrode processing file for the target workpiece. Furthermore, on the processing machine tool operation interface, you can select options such as loading files or importing programs to find and select the transmitted processing code file. The machine tool control system parses the processing code and extracts the parameter information to be processed. These parameter information include discharge current, pulse width, pulse interval, electrode motion trajectory, shaking mode, and may also include processing depth, feed speed, spindle speed, etc. Confirm the parameter information. After the machine tool reads the parameter information, the relevant parameter information will be displayed on the operation interface. Carefully check whether these parameters are correct, and if necessary, adjust and modify them.

[0082] Specifically, in this embodiment, the processing machine tool processes the target workpiece in the following manner:

[0083] Parse the electrode processing file and obtain the processing program from the electrode processing file, wherein the processing program includes multiple electrode subprograms, and each electrode subprogram includes an electrode identification corresponding to each processing electrode; control each processing electrode to load the corresponding electrode subprogram according to the electrode identification, so that when receiving a preset instruction, each processing electrode is controlled to run according to the corresponding electrode subprogram, and after each electrode subprogram runs, a target workpiece is obtained.

[0084] When the number of electrodes is 2 or more, different machining electrodes correspond to different electrode shapes and different corresponding electrode subroutines. Therefore, after parsing the electrode machining file to obtain the machining program, the corresponding electrode subroutine needs to be loaded according to the electrode identification corresponding to each machining electrode to prevent the electrode subroutine from being loaded onto the wrong electrode. Then, when installing the electrode shape on the machining machine, the electrode shape on the machining machine also needs to be marked so that the machining electrode set to the current electrode shape can be loaded into the corresponding electrode subroutine. After the electrode subroutine corresponding to each machining electrode is loaded, the workpiece can be machined through the start instruction, so that after the program runs, the target workpiece that meets the precision requirements can be obtained.

[0085] The electrode program design method provided in this embodiment first loads the parameter information of the target workpiece according to the target model file; then divides the target workpiece into at least one processing area according to the determined number of electrodes; and finally generates the corresponding electrode subroutine according to the size parameters and process parameters in each processing area. When the electrode subroutine provided in this embodiment controls the operation of the processing electrode, the processing accuracy of the target workpiece can be improved. Before controlling the processing machine tool for processing, this embodiment also pre-determines the electrode shape according to the shape parameters and structural parameters corresponding to each processing area, so that the target workpiece is produced according to the electrode shape determined in this embodiment, which helps to improve the processing accuracy and quality requirements of the target workpiece in the subsequent processing process. The electrode program design scheme provided in this embodiment is implemented on an electronic device other than the processing machine tool. In actual application, it is only necessary to load the corresponding electrode processing file through the processing machine tool, which has the beneficial effect of reducing the operating steps of the operator on the processing machine tool and improving the processing accuracy of the workpiece.
