Description

Technical Field

[0001] This application relates to the field of laser processing technology, and particularly to a method for detecting overtravel of machining codes in a laser cutting numerical control system. Background Art

[0002] In the field of laser cutting processing, numerical control machine tools are widely used in the cutting processing of various materials. To ensure that the equipment does not collide during movement, existing numerical control machine tools usually control the movement range of the equipment through external signals and axis travel limits set by software. However, during actual processing, due to factors such as non-standard material lengths and operator trial runs, the actual machining travel may not match the preset travel. The existing processing methods mainly rely on experienced operators to judge by eye or manually adjust the equipment position according to the axis travel limits. This method is not only inefficient but also prone to material waste and equipment failures due to human judgment errors.

[0003] Especially, during the laser cutting of pipes, due to the uncertainty of pipe lengths and different operating habits of operators, problems such as cutting interruptions and material waste caused by insufficient travel often occur. In addition, when the equipment reaches the limit position, an alarm will be triggered, requiring the operator to spend additional time dealing with the alarm, further reducing the processing efficiency.

[0004] In view of the above problems, the existing technology lacks a method that can automatically detect overtravel situations in machining codes and automatically adjust machining strategies or give early warning prompts according to the detection results.

[0036] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0037] In an embodiment of the present application, a method for detecting overtravel of machining codes in a laser cutting numerical control system is provided, which is applied to a workshop equipped with advanced laser cutting equipment and a corresponding numerical control system. The numerical control system can be seamlessly docked with CAM (Computer Aided Manufacturing) software and receive and parse the machining codes generated by the CAM software.

[0038] Please refer to Figure 1 As shown, the method includes:

[0039] S100: Receive the machining codes generated by the CAM software, and the machining codes include the machining length information of the pipe, parts and contours.

[0040] Specifically, before step S100 is executed, ensure that the CAM software has generated machining codes according to the design drawings. The machining codes describe in detail the machining length information of the pipe, parts and contours, as well as the starting coordinates of the machining path.

[0041] S200: Embed a limit travel detection macro program in the machining codes. The travel detection macro program is used to perform logical processing according to the starting coordinates, machining length and limit coordinates of the machining codes to determine whether there is an overtravel situation.

[0042] Specifically, embed a limit travel detection macro program in the generated machining codes. The macro program is designed to be able to read the starting coordinates, machining length and preset limit coordinates of the machining codes and perform logical processing to determine whether there is an overtravel situation.

[0043] In the macro program, the detection logics of the whole pipe detection, single part detection and single contour tool path are independent of each other, and can be flexibly configured by itself to select the execution order or the executed module.

[0044] S300: When executing the machining code, the travel detection macro program is used to sequentially detect the travel of the machining paths of the entire pipe, individual parts, and individual cutting profile tool paths, and obtain the detection results.

[0045] Specifically, when the machining code is executed, the travel detection macro program is automatically called to sequentially detect the travel of the machining paths of the entire pipe, individual parts, and individual cutting profile tool paths. For the entire pipe, the macro program calculates the difference between the pipe length and the limit coordinates of the equipment in the pipe direction, and compares it with the preset axis travel. For individual parts, the macro program also calculates the difference between the part length and the limit coordinates of the equipment in the corresponding direction and makes a comparison. For an individual cutting profile tool path, the macro program calculates the difference between the tool path length and the limit coordinates of the equipment in the cutting direction and makes a comparison.

[0046] S400: Adjust the execution logic of the machining code according to the detection results and preset logic.

[0047] Specifically, when the detection result indicates insufficient travel, a warning prompt is triggered, which includes a pop-up prompt and / or a sound prompt to notify the operator. The pop-up prompt directly displays relevant information on the software interface, and the sound prompt is issued through the audio system in the workshop.

[0048] The logical execution process of the above steps is as Figure 2 shown, and the application process of the method may include:

[0049] Suppose there is a batch of pipes that need to be cut into multiple parts, and the length and shape of each part are different. The operator uses CAM software to generate machining code according to the design drawings and embeds the travel detection macro program in the code. When starting to execute the machining code, the travel detection macro program first detects the travel of the entire pipe. Suppose the pipe length exceeds the limit of the equipment in the pipe direction. At this time, a warning prompt is triggered, and a pop-up message "The pipe is too long, please adjust or replace" is displayed on the software interface. At the same time, since this batch of pipes is of high value, the operator is prompted to handle it manually. The operator manually truncates the pipe to an appropriate length according to the prompt information and restarts the machining process. At this time, the travel detection macro program continues to detect the travel of individual parts and individual cutting profile tool paths, and adjusts the execution logic according to the detection results. For parts with insufficient travel, they are automatically discharged as waste according to the preset logic; for parts with sufficient travel, normal cutting machining is performed.

[0050] In this embodiment, the over-travel detection of the machining code is performed in advance, which avoids the problems of cutting interruption and material waste caused by insufficient travel, and improves the cutting efficiency. According to the detection results, the machining strategy is automatically adjusted or a warning prompt is given, effectively reducing the material waste problem caused by human judgment errors. By automatically detecting and processing the over-travel situation, the alarm problem triggered by the equipment reaching the limit position is avoided, and the equipment failure rate is reduced. By embedding macro programs in the code, flexible configuration can be performed according to different requirements, such as detecting the whole pipe, detecting a single part, and detecting a single contour, etc., increasing the operability of the equipment.

[0051] In some embodiments, the adjusting the execution logic of the machining code according to the detection result and the preset logic includes:

[0052] When the detection result is insufficient travel, the machining code triggers a warning prompt or jumps to the end;

[0053] When the detection result is insufficient travel, the value of the material is detected, compared with the value threshold in the preset logic, and a warning prompt or automatic waste discharge is selected according to the comparison result.

[0054] In specific implementation, the value of the material is judged according to the value threshold in the preset logic. If the material value is higher than the threshold, the system prompts the operator to handle it manually; if the material value is lower than the threshold, the system automatically discharges this part of the material as waste.

[0055] In this embodiment, the processing logic is flexibly adjusted according to the material value or processing requirements, which can adapt to different material values and processing requirements and reduce material loss.

[0056] In some embodiments, after adjusting the execution logic of the machining code according to the detection result and the preset logic, it further includes:

[0057] When calling the tail stock processing macro program to discharge the remaining material as waste.

[0058] In specific implementation, after adjusting the execution logic, if the remaining material still needs to be processed, the tail stock processing macro program is called to perform waste discharge operation on the remaining material.

[0059] In this embodiment, the management of the remaining pipe can be completed, and the material loss is reduced.

[0060] In some embodiments, the when the detection result is insufficient travel, the machining code triggers a warning prompt or jumps to the end, includes:

[0061] When the detection result is insufficient travel, the machining code converts the detection result into a control signal based on the ladder diagram logic, and drives the software interface to perform a pop-up prompt or jump to the end.

[0062] During specific implementation, the detection result is converted into a control signal (such as M67 Y51.1) through ladder diagram logic to drive a pop-up window on the software interface or jump to the end.
