Description

Technical Field

[0001] This invention relates to the field of CNC machining technology, specifically to a method and system for machining complex curves on a CNC grinding machine based on a curve table. Background Technology

[0002] The CNC system of a grinding machine is its brain. Researching how to simplify the operation of CNC grinding machines to achieve grinding processes on complex curves is a crucial aspect of CNC system research. With the continuous development of modern industry, the requirements for the precision and surface quality of mechanical parts are becoming increasingly stringent. Especially in industries such as steel, papermaking, and non-ferrous metals, rolls, as key components, directly affect product quality and production efficiency due to their surface quality and geometry. Traditional roll grinding technology is quite mature when handling simple geometries, but existing CNC machine tool control schemes have many shortcomings when facing complex curves and high-precision requirements. These include: cumbersome machining procedures requiring human intervention during processing, inability to guarantee uniform grinding speed leading to decreased grinding accuracy; and a lack of real-time monitoring, making it impossible to detect process execution, potentially causing the system to idle and resulting in unnecessary resource consumption.

[0003] With the development of computer technology and the upgrading of CNC systems, related supporting software is relatively mature. In order to address the above-mentioned problems encountered in the CNC grinding process, the existing technology discloses a CNC roll grinding machine and its control system and method, which proposes a way to generate machining instructions based on the basic parameters and curve information of the grinding machine set by the user. This method can realize grinding processes of arbitrary curve types. However, the grinding process is essentially a repetitive grinding process. The existing technology has low efficiency in repeatedly grinding the workpiece. There is an urgent need for a CNC grinding machine complex curve machining method and system based on curve tables to solve this problem. Summary of the Invention

[0004] In view of the above problems, the present invention is proposed to provide a CNC grinding machine complex curve machining method and system based on curve tables to overcome or at least partially solve the above problems.

[0005] To address the aforementioned technical problems, the embodiments of this application disclose the following technical solutions:

[0006] In a first aspect, embodiments of the present invention disclose a method for machining complex curves on a CNC grinding machine based on a curve table, comprising:

[0007] S100. Obtain the process G-code containing the curve table from user input;

[0008] S200. Load the process G code, process the G code according to preset rules, and generate executable cyclic machining G code; the executable cyclic machining G code is used to internally generate G code trajectory segments. During machining, the current is monitored during interpolation. During idle machining, interpolation stops and the machine starts running from the next machining trajectory segment.

[0009] S300. Execute the cyclic machining G code. During the execution of the G code, the machining trajectory is integrated, the load current is monitored, and the G code is edited online.

[0010] Furthermore, in S100, the user input containing the process G code of the curve table includes at least the parameter curve type, trajectory start and end points, and curve coefficient.

[0011] Further, in S200, the G-code is processed according to preset rules to generate executable cyclic machining G-code. The specific method includes: loading the process G-code N, obtaining the input cycle number P, the feed amount Q per cycle, the interrupt jump signal L, and generating executable cyclic machining G-code; first, the process G-code N is loaded, and then the machining path is repeatedly executed according to the cycle number P. In each cycle, the tool performs cutting according to the feed amount specified by the feed amount Q per cycle, and ensures that the tool retracts in a predetermined manner at the end of each cycle; at the same time, the system determines whether an interruption or jump is needed based on the interrupt jump signal L.

[0012] Furthermore, in S300, the cyclic machining G code is executed. During the execution of the G code, the machining trajectory is integrated. The specific method includes: merging multiple similar machining paths into a continuous trajectory; for multiple identical linear interpolations G1, the optimal path is calculated through an intelligent algorithm, and the repeated parts are eliminated, only the necessary feed and return operations are performed; for circular arc trajectories G2 and G3, the optimal circular arc connection method is calculated according to the machining needs to avoid unnecessary tool start and retraction segments.

[0013] Furthermore, the cyclic machining G-code is executed. During the execution of the G-code, the machining trajectory is integrated. The specific method also includes: optimizing the transition path by automatically generating the shortest and smoothest transition path by calculating the tool feed direction, speed and turning requirements.

[0014] Furthermore, in S300, during the execution of the G code, the load current is monitored. The specific method includes: acquiring the current signal value of the CNC grinding machine in the no-load state, setting the current value as a reference value, and when the CNC grinding machine starts executing the G code machining program, monitoring the load at the end of the grinding wheel in real time, comparing the load at the end of the grinding wheel with the reference value, thereby realizing the monitoring of the load current.

[0015] Furthermore, when the load at the end of the grinding wheel is the same as the reference value, it is determined that there is no load at the end of the grinding wheel, and the interrupt response judgment process is initiated. If the interrupt response does not occur, the interrupt response function is enabled, and the current Z-axis coordinate is not between the beginning and end of the curve, then the interrupt response state is entered, the system coordinates are updated, the cache is cleared, and system output is blocked. The process continues to determine whether the response has ended. If it has not ended, the process remains in the interrupt response state. After the response ends, the interrupt response process is exited, the current processing segment is skipped, and the next processing trajectory is planned from the current position.

[0016] Furthermore, in S300, the cyclic machining G code is executed. During the execution of the G code, online editing of the G code is implemented. The specific method includes: during the execution of the G code, when the deviation between the actual grinding path and the preset path is greater than a preset threshold, the running machine tool is paused to the feed holding state, the process G code is modified, and after the G code is modified, the CNC grinding machine is started again for machining. The CNC grinding machine runs according to the modified G code.

During the execution of the G-code, the method integrates the machining trajectory, monitors the load current, and performs online G-code editing. When a complex curve process G-code is input, the CNC system defines a machining cycle, sets machining parameters, and superimposes the imported G-code with the starting segment, retraction segment, and transition path to generate a complete machining cycle G-code.

[0031] Figure 1 This is a flowchart of a CNC grinding machine complex curve machining method based on a curve table, as described in Embodiment 1 of the present invention.

[0032] Figure 2 This is a schematic diagram of the structure of an electronic device in Embodiment 3 of the present invention. Detailed Implementation

[0033] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0034] To address the problems existing in the prior art, embodiments of the present invention provide a method and system for machining complex curves on a CNC grinding machine based on a curve table.

[0035] Example 1

[0036] This invention discloses a method for machining complex curves on a CNC grinding machine based on a curve table, such as... Figure 1 ,include:

[0037] S100. Obtain the process G-code containing the curve table input by the user; In S100 of this embodiment, the process G-code containing the curve table input by the user includes at least the parameter curve type, trajectory start and end points, and curve coefficients. Specifically, the user inputs the line type, parameter curve type, start and end points, and curve coefficients on the interface to generate a curve, which is then discretized into process G-codes composed of small line segments. The user-input process G-code can be the curve segment machining code generated by various CAM software, or it can be integrated into the CNC system, where the interface defines several curve line types, and the user sets the start and end points, line type combination type, and then discretizes the curves into small line segments to generate the process G-code.

[0038] S200. Load the process G-code, process the G-code according to preset rules, and generate executable cyclic machining G-code. The executable cyclic machining G-code is used to internally generate G-code trajectory segments. During machining, the current is monitored during interpolation. During idle machining, interpolation stops, and the machining starts from the next machining trajectory segment. In S200 of this embodiment, the G-code is processed according to preset rules to generate executable cyclic machining G-code. The specific method includes: loading process G-code N, obtaining the input cycle number P, the feed amount Q per cycle, the interrupt jump signal L, and generating executable cyclic machining G-code. First, process G-code N is loaded, and then the machining path is repeatedly executed according to the cycle number P. In each cycle, the tool performs cutting according to the feed amount specified by the feed amount Q per cycle, and ensures that the tool retracts in a predetermined manner at the end of each cycle. At the same time, the system determines whether an interruption or jump is needed based on the interrupt jump signal L.

[0039] Specifically, the G73.2 instruction is used to generate executable cyclic machining G-code; the G73.2 instruction is an extension of the G73 instruction, enabling more complex and flexible machining processes in the CNC system. Its functions include:

[0040] Offset process G-code: Offset the position or path of the input process G-code (such as G1, G2, G3, etc.).

[0041] Overlay transition path: Add transition segments to the machining path to ensure smooth tool feed and retraction.

[0042] Generate executable cycle machining code: Based on the input process G code, automatically generate cycle machining G code including the starting segment, process G code segment, retraction segment, transition segment, etc.

[0043] The process G-code (N_) is the basic instruction for executing cutting operations. Common process G-codes include: G1: Linear interpolation, typically used for linear tool feed. G2: Clockwise circular interpolation, used for clockwise circular path cutting. G3: Counterclockwise circular interpolation, used for counterclockwise circular path cutting. G0: Rapid positioning, typically used when the tool moves to a specified position. In the G73.2 instruction, the N_ parameter specifies the basic process G-code to be executed. This process G-code is the core of the entire machining cycle; each cycle is based on this G-code for path generation and tool operation. The cycle count P_ specifies the number of times the machining process needs to be repeated. If a cutting path requires multiple repetitions, the P_ parameter controls this repetition count. For example, if P = 5, it means the current machining path needs to be repeated 5 times. In each machining cycle, the tool cuts along the specified path until the set depth of cut or machining conditions are reached. The feed rate Q_ defines the tool feed rate in each cycle. This feed rate typically refers to the distance the tool moves in each of the X, Y, and Z axes. It determines the step size of the tool's cutting. Properly setting the feed rate Q_ not only improves machining efficiency but also avoids machining accuracy problems caused by excessive feed. For complex contour machining, the feed rate Q_ needs to be adjusted based on tool size, material hardness, cutting conditions, etc. The interrupt jump signal L parameter is used to define the interrupt jump signal when specific conditions occur during machining. In CNC systems, interrupt jumps are usually related to safety checks, tool wear detection, and machining path adjustments. The L signal can change the tool's trajectory in real time during machining or pause machining under certain conditions for adjustment. Setting the L parameter helps the operator or control system react quickly under specific conditions. For example, setting L=1 can interrupt the current operation when a deviation or malfunction occurs, while L=2 may jump to another preset path for machining.

[0044] In summary, the G73.2 instruction provides greater flexibility and operability for machining processes in CNC systems. By dynamically setting the process G-code, cycle count, feed rate, and interrupt jump signal, the operator can precisely control the process of each cutting cycle according to machining requirements. G73.2 not only enhances the stability of machining paths but also improves machining efficiency, reduces tool wear, and provides a more optimized solution for modern CNC machining.

[0045] S300. Execute the cyclic machining G code. During the execution of the G code, the machining trajectory is integrated, the load current is monitored, and the G code is edited online.

[0046] In S300 of this embodiment, the cyclic machining G code is executed. During the execution of the G code, the machining trajectory is integrated. The specific method includes: merging multiple similar machining paths into a continuous trajectory; for multiple identical linear interpolations G1, the optimal path is calculated by an intelligent algorithm, and the repeated parts are eliminated, and only necessary feed and return operations are performed; for circular arc trajectories G2 and G3, the optimal circular arc connection method is calculated according to the machining needs to avoid unnecessary tool start and retraction segments.

[0047] In some preferred embodiments, the cyclic machining G-code is executed, and during the execution of the G-code, the machining trajectory is integrated. The specific method further includes: optimizing the transition path by automatically generating the shortest and smoothest transition path by calculating the tool feed direction, speed and turning requirements.

[0048] In S300 of this embodiment, during the execution of the G code, the load current is monitored. Specifically, this monitoring includes: acquiring the current signal value of the CNC grinding machine in a no-load state, setting the current value as a reference value, and monitoring the load at the end of the grinding wheel in real time after the CNC grinding machine starts executing the G code machining program. The load at the end of the grinding wheel is compared with the reference value to monitor the load current. When the load at the end of the grinding wheel is the same as the reference value, it is determined that there is no load at the end of the grinding wheel, and the interrupt response judgment process is initiated. If no interrupt response occurs, and the interrupt response function is enabled, and the current Z-axis coordinate is not between the beginning and end of the curve, the interrupt response state is entered, the system coordinates are updated, the cache is cleared, and system output is blocked. The system continues to determine whether the response has ended; if not, it remains in the interrupt response state. After the response ends, the interrupt response process is exited, the current machining segment is skipped, and the next machining trajectory is planned from the current position.

[0049] In S300 of this embodiment, the cyclic machining G code is executed. During the execution of the G code, online editing of the G code is realized. The specific method includes: during the execution of the G code, when the deviation between the actual grinding path and the preset path is greater than a preset threshold, the running machine tool is paused to the feed holding state, the process G code is modified, and after the G code is modified, the CNC grinding machine is started again for machining. The CNC grinding machine runs according to the modified G code.

[0050] This embodiment discloses a CNC grinding machine complex curve machining method based on a curve table, comprising: acquiring user-input process G-code containing a curve table; loading the process G-code; processing the G-code according to preset rules to generate executable cyclic machining G-code; and executing the cyclic machining G-code. During the execution of the G-code, the method integrates the machining trajectory, monitors the load current, and performs online G-code editing. When a complex curve process G-code is input, the CNC system defines a machining cycle, sets machining parameters, and overlays the imported G-code with a starting segment, a retraction segment, and a transition path to generate a complete machining cycle G-code. With the help of a monitoring module, when encountering an empty cutting trajectory without machining, the system can exit early and enter the next trajectory segment, greatly improving machining efficiency and significantly simplifying the machining process. This method can be well applied to grinding, a scenario requiring repeated trajectory machining.
