[0002] The CNC system of the grinder is the brain of the grinder. The study of grinding technology for complex curves by simplifying the operation process of the CNC grinder is a crucial part of the research on the CNC system of the grinder. With the continuous development of modern industry, the industry has higher and higher requirements for the precision and surface quality of mechanical parts. Especially in the steel, papermaking, non-ferrous metals and other industries, the surface quality and geometry of the roller as a key component directly affect the quality and production efficiency of the product. Traditional roller grinding technology is quite mature in processing simple geometric shapes, but when faced with complex curves and high-precision requirements, the existing CNC machine tool control scheme has many shortcomings, such as: the processing procedure is cumbersome, human intervention is required during processing, the grinding speed uniformity cannot be guaranteed, resulting in a decrease in grinding accuracy; lack of real-time monitoring, unable to detect the execution of the process, resulting in the system may be idle, causing unnecessary resource consumption, etc.

[0003] With the development of computer technology, the replacement of CNC systems, and the maturity of related supporting software, in order to deal with the above-mentioned problems encountered in the processing of CNC grinders, the prior art discloses a CNC roll grinder and its control system and method, and proposes a method for generating processing instructions according to the basic parameters of the grinder and curve information set by user input. This method can realize the grinding process of any curve type, but the grinding process is essentially a process of repeated grinding. The prior art has low efficiency in repeated grinding of workpieces, and there is an urgent need for a complex curve processing method and system for CNC grinders 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 method and system for complex curve processing of a CNC grinder based on a curve table, which overcomes the above problems or at least partially solves the above problems.

[0005] In order to solve the above technical problems, the embodiments of the present application disclose the following technical solutions:

[0033] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0034] In order to solve the problems existing in the prior art, an embodiment of the present invention provides a method and system for processing complex curves of a CNC grinder based on a curve table.

[0035] Example 1

[0036] The present invention discloses a method for processing complex curves on a CNC grinder based on a curve table. 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, the trajectory start and end points, and the curve coefficient. Specifically, the user inputs the line type, parameter curve type, start and end points, and curve coefficient on the interface to generate the curve, which is discretized into a process G code composed of small line segments. Among them, the user inputs the process G code, which can be a curve segment processing code generated by various CAM software, or it can be integrated in the CNC system, and several curve line types are defined by the interface, and the user sets the start and end points, and the discretization into small line segments after the line type combination type generates the process G code.

[0038] S200. Load the process G code, process the G code according to preset rules, and generate executable cyclic processing G code. The executable cyclic processing G code is used to internally generate G code trajectory segments. During processing, the current is monitored during the interpolation process. During idle processing, the interpolation stops and the operation starts from the next segment of the processing trajectory. In S200 of this embodiment, the G code is processed according to preset rules to generate executable cyclic processing G code. The specific method includes: loading the process G code N, obtaining the input cycle number P, the feed amount Q each time, and the interrupt jump signal L, and generating an executable cyclic processing G code; first, the process G code N is loaded, and then the processing 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 each time, and ensures that the tool retracts in a predetermined manner at the end of each cycle; at the same time, the system will determine whether an interrupt or jump is required based on the interrupt jump signal L.

[0039] Specifically, the G73.2 instruction is used to generate executable cycle processing G code; the G73.2 instruction is an extension of the G73 instruction, which realizes a more complex and flexible processing process 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] Superimpose transition path: Add transition segments to the machining path to ensure smooth feed and retract of the tool.

[0042] Generate executable cycle processing code: Based on the input process G code, automatically generate cycle processing G code including tool start segment, process G code segment, tool retract segment, transition segment, etc.

[0043] Among them, the process G code (N_) is the basic instruction for performing cutting operations. Common process G codes include: G1: linear interpolation, usually used for linear feed of the tool. G2: clockwise circular interpolation, used to perform clockwise circular trajectory cutting. G3: counterclockwise circular interpolation, used to perform counterclockwise circular trajectory cutting. G0: rapid positioning, usually used when the tool moves to the 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, and each cycle will perform path generation and tool operation based on this G code. The number of cycles P_ refers to the number of repetitions required in the specified machining process. Assuming that a certain cutting path needs to be repeated for multiple times, the P_ parameter is used to control this number of repetitions. For example, if P=5, it means that the current machining path needs to be repeated 5 times. In each cycle machining, the tool will cut according to the specified path until the set cutting depth or machining conditions are reached. The feed amount Q_ defines the feed amount of the tool in each cycle. This feed amount usually refers to the distance the tool moves each time in the X, Y, and Z axis directions. It determines the step amplitude of the tool cutting. Reasonable setting of the feed amount Q_ can not only improve the processing efficiency, but also avoid the processing accuracy problem caused by excessive feed. For complex contour processing, the feed amount Q_ needs to be adjusted according to the tool size, material hardness, cutting conditions, etc. The interrupt jump signal L parameter is used to define the interrupt jump signal when a specific situation occurs during the processing. In the CNC system, the interrupt jump is usually related to safety inspection, tool wear detection, processing path adjustment, etc. The L signal can change the tool motion trajectory in real time during the processing, or suspend the processing under certain conditions for adjustment. The setting of the L parameter can help the operator or the control system to respond quickly under specific conditions. For example, setting L=1 can interrupt the current operation when a deviation or fault occurs, and L=2 may jump to another preset path for processing.

[0044] In summary, the G73.2 instruction provides higher flexibility and operability for process processing in the CNC system. By dynamically setting the process G code, number of cycles, feed rate and interrupt jump signal, the operator can accurately control the process of each cutting cycle according to the processing requirements. G73.2 not only enhances the stability of the processing path, but also improves the processing efficiency and reduces tool wear, providing a more optimized solution for modern CNC processing.

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

[0046] In S300 of the present embodiment, the cyclic processing G code is executed. During the execution of the G code, the processing trajectory is integrated. The specific method includes: merging multiple similar processing paths into a continuous trajectory, and for multiple identical linear interpolation G1, calculating the best path through an intelligent algorithm, eliminating repeated parts, and only performing necessary feed and return operations; for arc trajectories G2 and G3, calculating the optimal arc connection method according to processing needs to avoid unnecessary starting and retracting segments.

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

[0048] In S300 of this embodiment, during the execution of the G code, the load current is monitored. The specific method includes: obtaining the current signal value of the CNC grinder in the no-load state, setting the current value as a reference value, and when the CNC grinder starts to execute the G code processing 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, and monitoring the load current. When the load at the end of the grinding wheel is the same as the reference value, it is judged that there is no load at the end of the grinding wheel, and the interrupt response judgment process is performed. If the interrupt response does not occur, and the interrupt response function is turned on, and the current Z-axis coordinate is not between the head and tail of the curve, then the interrupt response state is entered, the system coordinates are updated, the cache is cleared, and the system output is blocked; continue to judge whether the response is completed, and if it is not completed, stay in the interrupt response state; after the response is completed, exit the interrupt response process, jump out of the current processing section, and start from the current position to plan the next processing trajectory.

[0049] In S300 of this embodiment, the cyclic processing G code is executed, and during the execution of the G code, the G code is edited online. 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, and the process G code is modified. After the G code is modified, the CNC grinder is started again for processing, and the CNC grinder runs according to the modified G code.

[0050] The present embodiment discloses a complex curve processing method for a CNC grinder based on a curve table, comprising: obtaining a process G code input by a user containing a curve table; loading the process G code, processing the G code according to a preset rule, and generating an executable cycle processing G code; executing the cycle processing G code, and realizing the integration of the processing trajectory, monitoring of the load current, and online editing of the G code during the execution of the G code. In the present invention, when a complex curve process G code is input, the CNC system defines a processing cycle, sets processing parameters, and generates a complete processing cycle G code after superimposing the imported G code with a tool segment, a tool retraction segment, and a transition path. Under the action of the monitoring module, when encountering an empty cutting trajectory without processing, it can jump out in advance and enter the next trajectory, which greatly improves the processing efficiency and significantly simplifies the processing process. It can be well applied to grinding, which requires repeated trajectory processing.
