Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machine tool control, more particularly to a double-turret double-spindle machine tool control system and method integrating multiple sensing technologies. BACKGROUND

[0002] Machine tools are commonly used for turning heavy parts, but ordinary machine tools generally have single functions, and a relatively complex part is often composed of multiple elements such as cylindrical surfaces, planes, holes, and grooves. Single-function machine tools are difficult to process multiple elements and cannot meet the processing needs of completing all processes on a machine at one time.

[0003] Nowadays, double-turret double-spindle machine tools are controlled by double spindles and double turrets to complete complex tasks on the same machine. As provided in the basic content of patent No. CN118342340A, in step a, it is mentioned that "the program and turret that can process both sides of the workpiece at the same time are set, so that the turret can process the workpiece symmetrically on both sides of the workpiece at the same time". The symmetric processing mode is used to synchronize the processing of both ends of a workpiece. Therefore, for the scenario of processing two different workpieces, different processing paths need to be set for double-spindle workpieces with uneven processing time and complexity, and the two different processing paths need to avoid spatial intersection to complete the double-turret collaborative work. When a turret is executing a task due to abnormal conditions (such as excessive load, vibration, or temperature), if no measures are taken, the processing risk will be aggravated. If measures are taken, such as reducing speed, the processing time of the turret will be prolonged, which may disrupt the original double-turret coordination schedule, and further cause displacement deviation accumulation, leading to path conflict risk.

[0004] Therefore, in view of the technical problems in actual production, a double-turret double-spindle machine tool control system and method integrating multiple sensing technologies are proposed. SUMMARY

[0005] The present application aims to solve the existing problems and provide a double-turret double-spindle machine tool control system and method integrating multiple sensing technologies compared to the prior art.

[0006] The purpose of the present application can be achieved by the following technical solution: a double-turret double-spindle machine tool control system integrating multiple sensing technologies, including a turret matching module, a path generation module, an execution control module, a multi-dimensional perception module, a path planning module, and a dynamic adjustment module. The turret matching module is used to identify double workpiece process parameters, decompose double workpiece independent subtasks, divide non-shared tools and shared tools, and match the main turret and the auxiliary turret corresponding to the double workpieces according to task information. The path generation module obtains the main turret non-shared tool sub-tasks, the vice turret non-shared tool sub-tasks and the shared tool sub-tasks, generates the main turret machining path and the vice turret machining path without spatial intersection interference through simulation analysis and sends them to the execution control module, the execution control module obtains the double workpiece process parameters and controls the double main shafts and double tool towers to work cooperatively according to the main turret machining path and the vice turret machining path; The multi-dimensional perception module obtains the machining data of the machine tool through the multi-dimensional sensor, judges whether the machining of the machine tool is normal according to the comparison and analysis of the machining data and the safety threshold, generates a regulation signal and sends it to the dynamic adjustment module when judging that it is not normal, adjusts the process parameters of the current task until the machining of the machine tool returns to normal, and in the adjustment process, the multi-dimensional perception module collects the machining displacement points in real time, judges whether there is a crossing risk in the double machining path according to the displacement deviation calculation and analysis, generates a path re-planning signal and sends it to the path planning module if there is a crossing risk, and performs dynamic path re-planning. The multi-dimensional perception module generates a parameter gradual recovery signal and sends it to the dynamic adjustment module and generates a path gradual recall signal and sends it to the path planning module when judging that the machining of the machine tool returns to normal during the continuous monitoring process.

[0007] Further, the tool tower matching module generates corresponding sub-task lists according to the double workpiece independent sub-tasks, each sub-task of the sub-task list has a required tool and an estimated time consumption, divides the non-shared tools and the shared tools according to the two sub-task lists, calculates the total machining time of all sub-tasks of a single workpiece, judges the complexity of the double workpiece according to the total machining time and the sub-task complexity, matches the main tool tower to the workpiece with high complexity, and matches the vice tool tower to the workpiece with low complexity.

[0008] Further, the process of obtaining the main turret machining path and the vice turret machining path includes: generating a main turret independent machining process according to the main turret non-shared tool sub-tasks, generating a vice turret independent machining process according to the vice turret non-shared tool sub-tasks, inserting the shared tool sub-tasks into the main turret independent machining process and the vice turret independent machining process respectively, and generating the main turret machining path and the vice turret machining path respectively according to the new machining processes; Simulate and display the main turret machining path and the vice turret machining path, check whether there is spatial intersection interference between the two machining paths, adjust the execution order of the shared tool sub-tasks if there is spatial intersection interference, and continue until there is no spatial intersection interference between the two machining paths.

[0009] Further, the process of judging whether the machining of the machine tool is normal includes: obtaining the machining data, specifically including the cutting load, the cutting temperature and the cutting vibration, comparing each parameter of the machining data with the corresponding safety threshold, judging that the machining of the machine tool is normal when each parameter in the machining data is within the corresponding safety threshold, continuing to machine, and otherwise judging that the machining of the machine tool is not normal.

[0010] Further, when the machine tool processing is abnormal, when the cutting load is greater than the cutting load safety threshold, the cutting load is determined to be abnormal, a first-level speed reduction cooling signal is generated, when the cutting temperature is greater than the cutting temperature safety threshold, the cutting temperature is determined to be abnormal, a second-level speed reduction cooling signal is generated, and when the cutting vibration is greater than the cutting vibration safety threshold, the cutting vibration is determined to be abnormal, a speed reduction and damping activation signal is generated, and the above signals are collectively referred to as a control signal.

[0011] Further, the multi-dimensional perception module collects the processing displacement points in real time, the processing displacement points are actual coordinate points collected by a laser displacement sensor, the theoretical processing displacement points set by the processing program are retrieved, and the displacement deviation vector is obtained by difference calculation of the theoretical processing displacement points and the processing displacement points. The displacement deviation vector is compared with the preset safety displacement deviation threshold, when the displacement deviation vector is greater than the preset safety displacement deviation threshold, it is judged that the double processing path has a risk of intersection, a path re-planning signal is generated, otherwise, it is judged that the double processing path does not have a risk of intersection, and a path maintenance signal is generated.

[0012] Further, after the dynamic adjustment module receives the parameter gradual recovery signal, a three-step recovery process is started, the first step is to set a percentage of the original parameters, the multi-dimensional perception module judges in real time whether there is a risk of processing path intersection, generates a path gradual recall signal when it is judged that there is a risk, and sends it to the path planning module for path dynamic recall, when it is judged that there is no risk, the second step is to set a percentage of the original parameters, and the risk of processing path intersection is judged in the same way, and the third step is executed in a loop, and in the continuous monitoring process, the stable recovery of the process parameters and the processing path is gradually completed.

[0013] The application also proposes a double-tool-tower double-spindle machine tool control method based on multi-sensing technology fusion, including the following steps: Step one, identify the double workpiece process parameters, divide the non-shared tools and shared tools by decomposing the double workpiece independent subtasks, and match the main tool tower and the auxiliary tool tower according to the corresponding task information; Step two, obtain the main tool tower, auxiliary tool tower non-shared tool subtasks and shared tool subtasks, generate the main tool tower processing path and the auxiliary tool tower processing path without spatial intersection interference through simulation analysis; Step three, obtain the double workpiece process parameters, and control the double spindle and double tool tower to work cooperatively according to the main tool tower processing path and the auxiliary tool tower processing path; Step four, judge whether the machine tool processing is normal according to the comparison and analysis of the processing data and the safety threshold; Step five, when judging abnormal, adjust the process parameters until the machine tool machining is normal, and collect the machining displacement points in real time during the adjustment process, judge whether the double path exists the cross risk according to the displacement deviation calculation and analysis, if exists, carry out the dynamic re-planning of the path; Step six, when the machine tool machining is normal, gradually complete the stable recovery of the process parameters and the machining path.

[0014] Compared with the prior art, the advantages of the present application are: 1. The scheme is to identify the double workpiece process parameters when the double-spindle multi-tool turret machine tool machines two different workpieces, so as to decompose the independent sub-tasks, divide the tool distribution, complete the tool turret matching and double-path non-crossing optimization, and based on the multi-sensing technology, the machine tool machining state is sensed in real time during the machine tool working, whether the machine tool machining is normal is judged, when judging abnormal, the regulation and control mechanism is started, the process parameters of the current task are adjusted until the machine tool recovers normal, at the same time, whether the double machining path exists the cross risk is judged in real time, the machining safety and precision are guaranteed by the real-time path optimization, the influence of abnormal response on the overall efficiency is minimized, a system architecture of double-path cooperation, multi-source sensing and intelligent decision is constructed, and the double-spindle, double-tool turret efficient cooperative machining is realized.

[0015] 2. Based on the above content, after the machine tool machining recovers normal, a three-step recovery program mechanism is started, and the machine tool machining state is continuously monitored, under the premise of ensuring the path safety, the stable recovery of the process parameters and the machining path is realized, and finally the system completely returns to the original optimized state, a reliable abnormal recovery solution for the double-tool turret numerical control machine tool is provided.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings; obviously, the described embodiments are only part of the embodiments of the present application, and not all the embodiments; based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative labor belong to the protection scope of the present application.

[0018] Embodiment one: the present application discloses a double-tool turret double-spindle machine tool control system with multi-sensing technology fusion, please refer to Figure 1, including a turret matching module, a path generation module, an execution control module, a multi-dimensional perception module, a path planning module, and a dynamic adjustment module, the turret matching module, the path generation module, the execution control module, and the multi-dimensional perception module are two-by-two bidirectional communication connections in sequence, and the multi-dimensional perception module is unidirectional communication connection with the path planning module and the dynamic adjustment module; Please refer to Figure 1 and Figure 2 The turret matching module is used to identify the double workpiece process parameters, and by decomposing the double workpiece independent subtasks, dividing the non-shared tools and shared tools, and matching the main turret and the auxiliary turret according to the task information, the specific process includes: According to the double workpiece independent subtasks, a corresponding subtask list is generated, each subtask of the subtask list has a required tool and an estimated time consumption, the non-shared tools and the shared tools are divided according to the two subtask lists, the total machining time of all subtasks of a single workpiece is calculated, the complexity of the double workpiece is judged according to the total machining time and the subtask complexity, the workpiece with high complexity is marked as workpiece A, and the workpiece with low complexity is marked as workpiece B, the workpiece A is matched with the main turret, and the workpiece B is matched with the auxiliary turret; By identifying the double workpiece process parameters when the double-spindle multi-turret machine tool processes two different workpieces, the independent subtasks are decomposed and the tool distribution is divided, the main and auxiliary turret matching is completed, and the main turret non-shared tool subtask, the auxiliary turret non-shared tool subtask, and the two-turret shared tool subtask are obtained.

[0019] The path generation module is used to obtain the main turret non-shared tool subtask, the auxiliary turret non-shared tool subtask, and the shared tool subtask, and by simulating analysis, the main turret machining path and the auxiliary turret machining path without spatial intersection interference are generated, and the acquisition process of the main turret machining path and the auxiliary turret machining path includes: According to the main turret non-shared tool subtask, the main turret independent machining process is generated, according to the auxiliary turret non-shared tool subtask, the auxiliary turret independent machining process is generated, the shared tool subtask is inserted into the main turret independent machining process and the auxiliary turret independent machining process respectively, and according to the new machining process, the main turret machining path and the auxiliary turret machining path are generated respectively; The main turret machining path and the auxiliary turret machining path are simulated and displayed, and it is checked whether there is spatial intersection interference between the two machining paths, if there is spatial intersection interference, the execution order of the shared tool subtask is adjusted until there is no spatial intersection interference between the two machining paths, the main turret machining path and the auxiliary turret machining path are sent to the execution control module, and if the two turrets apply for the same shared tool during the shared tool subtask execution distribution process, the main turret is forced to use first, and the auxiliary turret task enters the waiting queue; The execution control module acquires the process parameters of the two workpieces and establishes a dual working area that supports independent / linked control based on the main turret machining path and the secondary turret machining path. The process parameters control the dual spindles and dual turrets to work collaboratively in the dual working areas. Dynamic scheduling is achieved through "natural breakpoint insertion". On the basis of compatibility with the existing "dual turret collaboration", it effectively solves the problem of turret and tool resource competition and dual path optimization for different workpieces, so that the machining efficiency of different workpieces approaches the theoretical optimal value.

[0020] The multi-dimensional sensing module acquires machining data of the machine tool in the dual working areas through multi-dimensional sensors. Based on the comparison and analysis of the machining data and safety thresholds, it determines whether the machine tool is machining normally. The process includes: acquiring machining data, specifically including cutting load, cutting temperature and cutting vibration. Among them, a force / torque sensor is used to monitor the cutting load fluctuation at the spindle end, a temperature sensor is used to monitor the real-time temperature of the cutting tool, and a vibration sensor (accelerometer) is used to monitor cutting chatter. Each parameter of the machining data is compared with the corresponding safety threshold. When all parameters in the machining data are within the corresponding safety threshold, the machine tool is judged to be machining normally; otherwise, the machine tool is judged to be machining abnormally. When an abnormality is detected, a control signal is generated and sent to the dynamic adjustment module. When the cutting load exceeds the cutting load safety threshold, the cutting load is determined to be abnormal, and a first-level speed reduction cooling signal is generated. When the cutting temperature exceeds the cutting temperature safety threshold, the cutting temperature is determined to be abnormal, and a second-level speed reduction cooling signal is generated. When the cutting vibration exceeds the cutting vibration safety threshold, the cutting vibration is determined to be abnormal, and a speed reduction and damping activation signal is generated. The first-level speed reduction cooling signal, the second-level speed reduction cooling signal, and the micro-speed reduction and damping activation signal are collectively referred to as control signals. The process parameters of the current task are adjusted until the machining data is restored to within the safety threshold. The process parameters include cutting temperature, cutting process feed rate, and rotational speed. During the adjustment process, the multi-dimensional sensing module collects the processing displacement points in real time, calculates and analyzes the displacement deviation, and determines whether there is a risk of intersection between the two current processing paths. If so, it generates a path replanning signal and sends it to the path planning module to perform dynamic path replanning. The machining displacement point is the actual coordinate point collected by a laser displacement sensor (grating ruler / encoder). The theoretical machining displacement point set in the machining program is retrieved, and the displacement deviation vector is obtained by calculating the difference between the theoretical machining displacement point and the machining displacement point. The displacement deviation vector is compared with a preset safe displacement deviation threshold. When the displacement deviation vector is greater than the preset safe displacement deviation threshold, it is determined that there is a risk of intersection between the two current processing paths, and a path replanning signal is generated. Otherwise, it is determined that there is no risk of intersection between the two current processing paths, and a path maintenance signal is generated. In the process of verifying whether the trajectories exist spatial cross interference, the minimum distance of the two machining paths at the same timestamp is obtained. When the minimum distance is less than the preset safety distance, it indicates that the two machining paths exist spatial cross interference risk. The common tool sub-task is redistributed to adjust the machining path until the minimum distance between the two is greater than or equal to the preset safety distance. At this time, it indicates that the two machining paths do not exist spatial cross interference risk.

[0021] Based on the real-time sensing of the machine tool processing state by multiple sensing technologies, it is judged whether the machine tool processing is normal. When it is judged to be abnormal, the regulation mechanism is started to adjust the process parameters of the current task until the machine tool returns to normal. At the same time, it is judged in real time whether the double machining path exists cross risk to guarantee the machining safety and precision by real-time path re-optimization. The closed-loop control system of "real-time sensing-intelligent decision-making-collaborative execution" effectively solves the core problems such as precision maintenance, risk state sensing, adaptive adjustment and optimization of double-tool turret machine tool in compound machining, and maximally reduces the influence of abnormal response on overall efficiency.

[0022] Embodiment two: please refer to Figure 1 and Figure 3 In the continuous monitoring process, when it is judged that the machine tool processing returns to normal, the parameter gradual recovery signal is generated and sent to the dynamic adjustment module, and the path gradual callback signal is generated and sent to the path planning module; After the dynamic adjustment module receives the parameter gradual recovery signal, a three-step recovery program is started. In the first step, a percentage of the original parameters is recovered. In this process, the multi-dimensional sensing module judges in real time whether there is a machining path cross risk. When it is judged that there is a risk, the path gradual callback signal is generated and sent to the path planning module for path dynamic callback. When it is judged that there is no risk, a percentage of the original parameters is recovered in the second step. Similarly, it is judged whether there is a machining path cross risk. In this way, the third step is executed. In the continuous monitoring process, the stable recovery of the process parameters and the machining path is gradually completed; After the machine tool processing returns to normal, the three-step recovery program mechanism is started, and the machine tool processing state is continuously monitored. On the premise of ensuring path safety, the stable recovery of the process parameters and the machining path is realized, and finally the system completely returns to the original optimized state, providing a reliable abnormal recovery solution for double-tool turret CNC machine tools.

[0023] According to the combination of embodiment one and embodiment two, the double-tool turret double-spindle machine tool control method based on multiple sensing technologies includes the following steps: Step one, identify the double workpiece process parameters, divide the non-common tool and the common tool by decomposing the double workpiece independent sub-task, and match the main tool turret and the auxiliary tool turret according to the corresponding task information; Step two, obtain the main turret, the secondary turret non-shared tool sub-tasks and shared tool sub-tasks, and generate the main turret machining path and the secondary turret machining path without spatial intersection interference through simulation analysis; Step three, obtain the double workpiece process parameters, and control the double spindle and double turret cooperative work according to the main turret machining path and the secondary turret machining path; Step four, judge whether the machine tool machining is normal according to the comparison and analysis of the machining data and the safety threshold; Step five, when it is judged to be abnormal, adjust the process parameters until the machine tool machining is normal, and collect the machining displacement points in real time during the adjustment process, judge whether the double path exists the intersection risk according to the displacement deviation calculation and analysis, if it exists, perform the path dynamic re-planning; Step six, when the machine tool machining is normal, gradually complete the stable recovery of the process parameters and the machining path.

[0024] As shown above: the double spindle and double turret machine tool machining two different workpieces are recognized, the double workpiece process parameters are obtained, the independent sub-tasks are divided, the tool distribution is completed, the turret matching and the double path non-intersection optimization are completed, the machine tool machining state is sensed in real time based on the multiple sensing technology during the machine tool work, and whether the machine tool machining is normal is judged; When it is judged to be abnormal, the regulation and control mechanism is started, the process parameters of the current task are adjusted until the machine tool is normal, and at the same time, whether the double machining path exists the intersection risk is judged in real time, so as to realize the real-time path optimization, guarantee the machining safety and precision, and reduce the influence of abnormal response on the overall efficiency to the maximum extent; After the machine tool machining is normal, the three-step recovery program mechanism is started, and the machine tool machining state is continuously monitored, the stable recovery of the process parameters and the machining path is realized under the premise of ensuring the path safety, and finally the system completely returns to the original optimized state, a reliable abnormal recovery solution for the double turret numerical control machine tool is provided, and the machining efficiency, precision stability and equipment reliability are significantly improved.

[0025] In addition, it needs to be supplemented that the file involves multiple threshold comparisons, the threshold or the preset value, the preset range and the like are set for result comparison and analysis, so as to judge good and bad, and the size value thereof is set according to the large model analysis of sample data and the combination of artificial experience, and is also adjusted appropriately through the seasonal or rational influence conditions.
