Description

Technical Field

[0001] This application belongs to the field of beveling technology, and more specifically, it relates to a parameter setting and laser processing control method, device, equipment and storage medium. Background Technology

[0002] To ensure welding quality, the areas to be welded on the workpieces are machined before welding, creating a bevel. Beveling can be done using a beveling machine. Compared to a planar machining machine, a beveling machine has a more complex structure and control technology. It adds A-axis and B-axis axes that allow the machining head to swing at specific angles. For example, when a 30° bevel needs to be machined on a sheet metal, the machining head can be swung to a 30° angle with the normal to the plane to be machined.

[0003] Therefore, in order for the beveling machine to adapt to the processing requirements of different beveling angles, multiple beveling process parameters corresponding to different processing angles are usually preset on the beveling machine. Research and development personnel need to spend a lot of time debugging the process parameters. Summary of the Invention

[0005] The technical solution adopted in this application is: a parameter setting method, characterized by comprising the following steps:

[0006] Multiple preset processing angles are preset, and each preset processing angle corresponds to a set of process processing parameters. The processing angle refers to the angle between the axis of the processing head and the normal of the processing surface in the workpiece to be processed.

[0007] An angle range is set according to the preset machining angle, and the machining parameters corresponding to a certain machining angle within the angle range are calculated based on the machining parameters corresponding to the preset machining angles at the two endpoints of the angle range. Here, a certain machining angle within the angle range can be defined as the calculated machining angle.

[0008] The calculated machining angle is determined according to the angle definition logic, which determines the corresponding machining parameters of the process.

[0009] As can be seen, in the laser processing parameter setting method of this application, multiple preset processing angles and their corresponding process processing parameters are preset. An angle range is set by the preset processing angles. Then, the process processing parameters corresponding to a certain processing angle in the angle range are calculated according to the process processing parameters corresponding to the preset processing angles at the two endpoints of the angle range. Then, the calculated processing angle corresponding to the calculated process processing parameters is determined according to the angle definition logic, so that a process processing parameter corresponding to a cutting angle is generated in the set angle range, which can improve the processing accuracy of the equipment for workpieces with different processing requirements.

[0022] The process parameters include the processing air pressure, and the preset calculation formula includes:

[0023] Pr c =(Pr a +Pr b ) / 2, where Pr a and Pr b The processing air pressures Pr and Pr are the preset processing angles corresponding to the two endpoints of the angle range, respectively. c The processing air pressure corresponding to the calculated processing angle within the aforementioned angle range;

[0024] The processing parameters include processing power, and the preset calculation formula includes:

[0025] P c =(P a +P b ) / 2, where P a and P b The processing power P corresponds to the preset processing angle at each of the two endpoints of the angle range. c The processing power corresponding to the calculated processing angle within the aforementioned angle range;

[0026] The processing parameters include the processing follow-up height, and the preset calculation formula includes:

[0048] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0049] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0050] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0052] This application provides a parameter setting method for setting the process parameters required when laser processes a workpiece. For example, it can set the process parameters required when laser cuts or welds a workpiece, and in particular, it can set the required process parameters for laser processing of workpieces with processing angle requirements.

[0053] Taking laser cutting of a workpiece as an example, laser cutting uses a fiber laser to generate a laser source, which is then irradiated onto the surface of the workpiece through a laser cutting head. This causes the workpiece surface to melt rapidly, and simultaneously, auxiliary gas blown out coaxially with the laser beam assists in oxidation or removes the molten material, thereby forming a cut of the desired shape on the workpiece. Laser cutting has advantages such as high and concentrated laser energy, minimal deformation of the workpiece, smooth and slag-free cut surface, and minimal need for subsequent processing of the cut workpiece.

[0054] In laser cutting, laser beveling machines have been developed to better suit industries such as engineering welding and shipbuilding. The beveling process requires a control system to move the laser cutting head along the cutting trajectory to create a bevel on the workpiece. However, the control technology and beveling process of laser beveling machines are relatively complex. The process parameter interface requires setting multiple windows, and different beveling process parameters need to be manually adjusted and input based on the bevel cutting angle.

[0055] See Figure 1 This application provides a method for setting laser processing parameters, including the following steps:

[0056] Step S100: Preset multiple preset machining angles, each preset machining angle corresponding to a set of process parameters.

[0057] The machining angle refers to the angle between the axis of the machining head and the normal to the machining surface of the workpiece. When a laser is used to cut a workpiece, the machining head can refer to the cutting head.

[0058] In the above embodiments, multiple preset processing angles are preset, and each preset processing angle corresponds to a set of process processing parameters. This means that at least two preset processing angles need to be preset, and a set of process processing parameters is preset for each preset processing angle. For example, two preset processing angles can be preset as 0° and 15°, and the preset process processing parameter corresponding to the preset processing angle of 0° is A, and the preset process processing parameter corresponding to the preset processing angle of 15° is B.

[0059] Step S300: Set an angle range according to a preset machining angle, and calculate the machining parameters corresponding to a certain machining angle in the angle range according to the machining parameters corresponding to the preset machining angles at the two endpoints of the angle range.

[0060] Within this range, a specific machining angle can be defined as a calculated machining angle. It should be noted that a calculated machining angle refers to the machining parameters corresponding to that angle being calculated using a preset formula, not that a specific machining angle within the range is calculated directly.

[0061] For example, the specific method of "setting an angle range according to a preset processing angle" can be to set an angle range between every two preset processing angles with similar values ​​in an increasing or decreasing direction. Assuming that the preset processing angles are 0°, 15°, and 30°, "forming an angle range between every two preset processing angles with similar values" can refer to the angle range of 0° to 15° and the angle range of 15° to 30°.

[0062] In addition, in some embodiments, the above step S300 can be specifically achieved by presetting one or a set of calculation formulas in the equipment system. When multiple preset processing angles and their corresponding process processing parameters are preset in the equipment system, the system can calculate the process processing parameters of a certain processing angle within the angle interval formed between two preset processing angles with similar values ​​based on each preset processing angle and its corresponding process processing parameters and through the calculation formula.

[0063] Of course, in other embodiments, step 300 above can also be implemented by manually calculating the process parameters of a certain processing angle within the angle range formed between two preset processing angles with similar values ​​using a preset calculation formula, and the process parameters can be set in the system.

[0064] Step S500: Determine the calculated machining angle corresponding to the calculated process parameters according to the angle definition logic.

[0065] In other words, after calculating the machining parameters corresponding to a certain machining angle within the angle range according to the predetermined calculation formula, the machining angle corresponding to the calculated machining parameters can be determined through the angle definition logic.

[0066] For example, there are two preset machining angles, 0° and 15°. The preset machining parameter corresponding to the preset machining angle of 0° is A, and the preset machining parameter corresponding to the preset machining angle of 15° is B. The machining parameter a can be calculated based on the machining parameter A and machining parameter B and the preset calculation formula. Then, the angle definition logic can be used to determine which calculated machining angle corresponds to the machining parameter a. For example, the angle definition logic can determine that the calculated machining angle corresponding to the machining parameter a is 10° within the range of 0° to 15°.

[0067] As can be seen, in the laser processing parameter setting method of this application, multiple preset processing angles and their corresponding process processing parameters are preset. An angle range is set by the preset processing angles. Then, the process processing parameters corresponding to a certain processing angle in the angle range are calculated according to the process processing parameters corresponding to the preset processing angles at the two endpoints of the angle range. Then, the calculated processing angle corresponding to the calculated process processing parameters is determined according to the angle definition logic, so that a process processing parameter corresponding to a cutting angle is generated in the set angle range, which can improve the processing accuracy of the equipment for workpieces with different processing requirements.

[0068] In addition, the process processing parameters generated in the laser processing parameter setting method of this application are calculated by a preset calculation formula, and the processing angle corresponding to the calculated process processing parameters is determined by the angle definition logic. This method eliminates the need for manual adjustment of process processing parameters for a certain processing angle, which can reduce manual pressure and improve the automation of the equipment.

[0069] Furthermore, when setting parameters for bevel cutting, different bevels have different angle cutting requirements. The cutting angle of the bevel is generally between -45° and 45°, that is, the angle between the laser cutting head and the normal of the cutting surface of the workpiece is generally between -45° and 45°. In order for the laser bevel cutting machine to cut bevels with various angle requirements, multiple cutting layers are usually preset on the laser bevel cutting machine. For example, the process cutting parameter is set as A when the angle is 0°, the process cutting parameter is set as B when the angle is 0° to 15°, the process cutting parameter is set as C when the angle is 15° to 30°, and the process cutting parameter is set as D when the angle is 30° to 45°. Alternatively, the absolute value of the range of -45° to 0° can be taken and then processed into layers according to the 0° to 45° cutting layer.

[0070] However, since the angle range of 0° to 15° is quite large, if any angle between 0° and 15° is processed according to the process cutting parameter B corresponding to the angle of 15°, the processing accuracy may be low. If the preset angle range is further narrowed, multiple sets of process cutting parameters need to be manually adjusted, and these process cutting parameters need to be entered into the process parameter window of the equipment, which places greater demands on the equipment's R&D and operation personnel.

[0071] Therefore, in some embodiments, see Figure 2 Parameter setting methods may also include:

[0072] Step S700: Determine all machining angles within the angle interval formed between the preset machining angle and the calculated machining angle, and define the process machining parameters corresponding to all machining angles within the angle interval as the process machining parameters corresponding to the preset machining angle or the calculated machining angle.

[0073] It is understandable that although a certain calculated machining angle and the corresponding process machining parameters are determined in step S500, there may still be an angle range between the calculated machining angle and the preset machining angle. Therefore, step S700 can determine which process machining parameters to use for the angle within the angle range.

[0074] For example, there are two preset machining angles, 0° and 15°. The preset machining parameter corresponding to the preset machining angle of 0° is A, and the preset machining parameter corresponding to the preset machining angle of 15° is B. The machining parameter a can be calculated based on the machining parameters A and B using a preset calculation method. Then, the calculated machining angle corresponding to the machining parameter a can be determined to be 10° within the range of 0° to 15° according to the angle definition logic. At this time, the angle range of 0° to 15° is further divided into two angle ranges, namely the angle range of 0° to 10° and the angle range of 10° to 15°. Therefore, any angle within the angle range of 0° to 10° can be determined by step S700 to process the workpiece according to the machining parameter a corresponding to the calculated machining angle of 10°. Similarly, any angle within the angle range of 10° to 15° can be determined to process the workpiece according to the machining parameter B corresponding to the calculated machining angle of 15°.

[0075] In other words, since a new set of process parameters and their corresponding calculated processing angles are determined within the set angle range, this method can further narrow the angle processing range corresponding to each set of process parameters.

[0076] In step S100, the control system can obtain multiple preset processing angles and their corresponding process parameters by acquiring manually input information, or multiple preset processing angles and their corresponding process parameters can be preset in the control system. The process parameters may include the laser processing speed, processing focus, processing air pressure, processing power, and processing follow-up height.

[0077] In step S300, when the processing parameters include processing speed, the preset calculation formula may include the calculation formula for processing speed in laser processing, that is:

[0078] V C =(V a +V b ) / 2;

[0079] Among them, V a and V b V represents the processing speed corresponding to the preset processing angles at the two endpoints of the angle range. C This refers to the processing speed corresponding to the calculated processing angle within the angular range.

[0080] In some embodiments, when the process parameters further include the processing focus, the preset calculation formula may also include the calculation formula for the processing focus in laser processing, namely:

[0081] F c =(F a +F b) / 2;

[0082] Among them, F a and F b F represents the machining focus corresponding to the preset machining angles at the two endpoints of the angle range. c This refers to the machining focus corresponding to the calculated machining angle within the angle range.

[0083] In some embodiments, when the process parameters further include processing gas pressure, the preset calculation formula may also include the calculation formula for processing gas pressure in laser processing, namely:

[0084] Pr c =(Pr a +Pr b ) / 2;

[0085] Among them, Pr a and Pr b The processing air pressures Pr and Pr are the preset processing angles corresponding to the two endpoints of the angle range, respectively. c This refers to the processing air pressure corresponding to the calculated processing angle within the angular range.

[0086] In some embodiments, when the process parameters also include processing power, the preset calculation formula may further include the calculation formula for processing power in laser processing, namely:

[0087] P c =(P a +P b ) / 2;

[0088] Among them, P a and P b P represents the processing power corresponding to the preset processing angles at the two endpoints of the angle range. c This refers to the processing power corresponding to the calculated processing angle within the angular range.

[0089] In some embodiments, when the process parameters further include the processing follow-up height, the preset calculation formula may also include the calculation formula for the processing follow-up height in laser processing, namely:

[0090] H c =(H a +H b ) / 2;

[0091] Among them, H a and H b The machining follow-up heights, H, are the preset machining angles at the two endpoints of the angle range. c This is the machining follow-up height corresponding to the calculated machining angle within the angle range.

[0092] It should be noted that when calculating the process parameters corresponding to the processing angle, one or more of the above-mentioned laser processing process parameters, including processing speed, processing focus, processing air pressure, processing power, and processing follow-up height, can be selected according to the object to be laser processed and the laser processing accuracy requirements. For processing process parameters that are not calculated, the same processing process parameter can be selected as the one corresponding to one of the preset processing angles at the two ends of the angle range.

[0093] Of course, laser processing parameters are not limited to processing speed, processing focus, processing gas pressure, processing power, and processing follow-up height, and are not limited here.

[0094] See Figure 3 In some embodiments, the angle definition logic in step S500 may specifically include:

[0095] Step S510: Select the machining angle within the angle range and control the machining head to perform trial machining on the workpiece according to the calculated process parameters.

[0096] Specifically, after the process parameters corresponding to a certain processing angle within the set angle range are calculated by the preset calculation formula, multiple processing angles can be selected within the angle range, so that the processing head can perform trial processing on the workpiece according to the calculated process parameters at each selected processing angle.

[0097] For example, when the process parameter corresponding to a certain calculated processing angle between 0° and 15° is calculated according to the preset calculation formula, the processing head can use the process parameter a to perform trial processing on the workpiece when the processing angle is 1°, when the processing angle is 2°, ... and when the processing angle is 14°.

[0098] Step S520: Determine the calculated machining angle corresponding to the calculated process parameters based on the trial machining results.

[0099] Specifically, after the workpiece is trial-processed in step S510, the processing effect of the calculated process parameters at a certain processing angle can be determined based on the trial processing results on the workpiece, and this processing angle can be determined as the calculated processing angle corresponding to the process parameters.

[0100] For example, if the machining head performs trial machining on the workpiece using process machining parameter 'a' at machining angles of 1°, 2°, ..., and 14°, and it is determined that the machining head achieves the best machining effect on the workpiece at a machining angle of 10°, then the calculated machining angle corresponding to process machining parameter 'a' can be determined as 10°.

[0101] Of course, in some other embodiments, the angle definition logic in step S500 may also specifically include:

[0102] Calculate the median angle within the angle range;

[0103] The calculated machining angle corresponding to the calculated process parameters is defined as the middle angle within the angle range.

[0104] For example, when the preset processing angles at the two endpoints of the set angle range are 0° and 15° respectively, the calculated processing angle corresponding to the calculated process parameters can be defined as the midpoint between 0° and 15°, which is 7.5°.

[0105] See Figure 4 This application also provides a laser processing control method, which includes the parameter setting method described above, and the method further includes the following steps:

[0106] Step S1000: Obtain the machining angle of the workpiece.

[0107] Step S3000: Determine the process parameters corresponding to the machining angle from the parameters set in the parameter setting method.

[0108] Specifically, after obtaining the machining angle of the workpiece, it is necessary to match the corresponding process parameter among the parameters set by the parameter setting method.

[0109] For example, the parameter setting method sets the process machining parameter as A when the preset machining angle is 0°, the process machining parameter as B when the preset machining angle is 15°, and the process machining parameter corresponding to the calculated machining angle of 10°, which is between the preset machining angles of 0° and 15°, as a, determined by a preset calculation formula and angle definition logic. Therefore, assuming the machining angle is 10°, the process machining parameter corresponding to the machining angle of 10° can be determined as a.

[0110] In addition, in some embodiments, the corresponding process parameters within the angle range are defined. For example, the process parameter corresponding to the range between 0° and 10° is defined as 'a', and the process parameter corresponding to the range between 10° and 5° is defined as 'B'. Therefore, assuming that the processing angle is 7°, it can be determined that the processing angle 7° is within the range of 0° to 10°, that is, the process parameter corresponding to the processing angle 7° is 'a'.

[0111] Step S5000: Control the machining head to process the workpiece according to the process parameters.

[0112] In some embodiments, step S1000 may further include:

[0113] Step S1100: Obtain the actual machining angle of the workpiece;

[0114] Step S1300: Obtain the machining angle by taking the absolute value of the actual machining angle.

[0115] It's understandable that in laser processing, such as laser cutting, the cutting angle of the workpiece can be negative—that is, the angle between the processing head and the normal to the workpiece's surface being processed is negative. Positive and negative angles are simply different in the direction of the angle formed between the processing head and the normal to the surface. Therefore, even when the actual processing angle of the workpiece is negative, the processing parameters corresponding to a positive angle can be used. That is, when the actual processing angle of the workpiece is negative, its absolute value can be taken to obtain the final processing angle. This angle can then be used to determine the processing parameters, allowing the processing head to process the workpiece using these parameters. In other words, this method only requires setting the processing parameters corresponding to laser processing angles within the positive angle range, reducing the complexity of parameter settings and improving the automation level of the equipment.

[0116] For example, when the actual machining angle of the workpiece is -15°, the absolute value of the actual machining angle -15° can be taken as |-15°| to obtain the machining angle of the workpiece as 15°. Then, the corresponding process parameters for machining angle 15° can be determined in the parameters set by the parameter setting method, so that the machining head can process the workpiece according to the corresponding process parameters for machining angle 15°.

[0117] Of course, in some other embodiments, during the parameter setting process, after setting the process parameters corresponding to the positive angle, the process parameters can be copied, and the copied process parameters can be linked with the negative angle symmetrical to the positive angle. Alternatively, during the parameter setting process, after setting the process parameters corresponding to the positive angle, the process parameters corresponding to the negative angle symmetrical to the positive angle can be linked with the process parameters corresponding to the positive angle.

[0118] The negative angle that is symmetrical to the positive angle refers to the angle with 0° as the point of symmetry. For example, the negative angle that is symmetrical to the angle 5° is -5°.
