Description

Technical Field

[0001] This invention belongs to the field of mechanical mold processing technology, and in particular relates to a CNC automated processing technology for mechanical molds oriented towards rapid reconfiguration manufacturing. Background Technology

[0002] As the manufacturing industry undergoes a profound transformation towards multi-variety, small-batch, and customized production, the market's demands for rapid product iteration continue to rise. Consequently, the processing needs of mechanical molds exhibit significant characteristics of high-frequency model changes and rapid response. Traditional batch-based and fixed mold processing models are no longer sufficient to meet the flexible production needs of the current manufacturing industry, necessitating processing technologies with rapid reconfiguration capabilities to support industry development.

[0003] The current industry standard for mechanical mold processing technology requires separate processing flow planning for different specifications and types of molds, along with dedicated tooling fixtures and processing equipment. Key steps such as equipment debugging, tool changing, processing parameter setting, and mold clamping and positioning are completed manually, forming a traditional model of one processing solution for one mold.

[0004] When faced with mold changeover requirements, the entire process planning and equipment debugging need to be carried out again, resulting in excessively long changeover cycles and extremely poor reconfigurability. The reliance on manual operation for many key links not only increases labor costs but also makes it easy for human error to affect the stability of processing accuracy. The degree of automation is low, and there is a lack of real-time perception and adaptive adjustment mechanisms for abnormal situations such as tool wear, material deviation, and equipment failure during the processing. Once a problem occurs, it can easily lead to the generation of batches of scrap, further increasing production costs.

[0026] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Please see Figure 1-5 This invention relates to a CNC automated machining process for mechanical molds for rapid reconfiguration manufacturing, comprising the following steps: S1: First, based on the functional characteristics of mechanical molds in forming, positioning, guiding, and venting, as well as the machining accuracy requirements of dimensional tolerances, surface roughness, and geometric tolerances, a modular design concept is adopted to decompose the complete mechanical mold into several standardized modules, such as cavity modules, core modules, guiding modules, positioning modules, and ejection modules. Then, feature information is collected for each standardized module, including the module's dimensional parameters, material information, machining features, machining priority, assembly relationships, and compatible machining equipment models. Finally, the collected module feature information is stored in a standardized format to build a mold module feature library, supporting the rapid retrieval, calling, and updating of module information.

[0028] S2: Based on the feature information of the mold module to be processed, a quick search is performed through the mold module feature library to match the corresponding basic machining parameter template. The machining parameter template library presets standard machining parameters for different materials and machining types, including cutting speed, feed rate, depth of cut, tool type, and machining allowance. Subsequently, combined with the specific size and accuracy requirements of the module to be processed, a genetic algorithm combined with finite element simulation analysis is used to optimize the parameters. The specific process is as follows: with cutting speed, feed rate, and depth of cut as optimization variables, and with the goal of maximizing machining efficiency and minimizing machining error, a fitness function is constructed. Iterative optimization is performed through selection, crossover, and mutation operations of the genetic algorithm, and cutting force and cutting temperature data obtained by finite element simulation are used as constraints. Finally, the optimal combination of machining parameters is obtained, and a standardized machining task parameter package containing machining logic instructions, parameter configuration information, and a draft toolpath planning is generated.

[0029] S3: Based on an open CNC system architecture, it calls the logical instructions in the machining task parameter package generated by S2. It adopts a modular programming concept to decompose the machining control logic into several functional sub-modules such as tool control sub-module, axis linkage control sub-module, and auxiliary equipment control sub-module. Through the dynamic combination of sub-modules, the machining logic can be quickly reorganized. At the same time, the CNC system is based on a standardized communication protocol to automatically identify the hardware interface types of machining equipment, inspection equipment, and material transfer equipment, complete the adaptive configuration of interface parameters, and realize the collaborative linkage between various devices.

[0030] S4: Based on the reconfigured information, the CNC system issues control commands to control the robotic arm to automatically grasp and clamp the mold module to be processed, control the tool magazine to automatically change the corresponding tools, and simultaneously start the cooling and lubrication system. According to the planned tool path, it drives the machining axes of the machining equipment to move in coordination to complete the automated machining of the mold module. During this process, the material conveying equipment automatically delivers the module to be processed to the machining station according to the processing progress, and transfers the processed module to the inspection station, realizing the fully automated flow of the processing process.

[0031] Step S5: During the machining process, the machine vision equipment collects image information of the machined surface of the mold module in real time to detect defects such as roughness, scratches, and burrs on the machined surface. At the same time, the machining dimensional accuracy is measured. The cutting force data during the machining process is collected by the force sensing equipment to judge tool wear and abnormal machining load. The detected quality data is compared with the preset accuracy threshold and force fluctuation threshold. If an abnormality is detected, the CNC system handles it according to the severity of the abnormality. In case of minor abnormality, the cutting speed, feed rate and other machining parameters are automatically adjusted. In case of severe abnormality, the machining is immediately suspended and an alarm signal is issued to remind the staff to troubleshoot the fault.

[0032] Step S6: Store the parameter configuration information, equipment operation data, and quality inspection data during the processing into a unified database to form a complete processing data traceability chain, which facilitates the traceability and analysis of subsequent product quality issues. Based on the accumulation and analysis results of processing data, continuously update the standard parameters in the processing parameter template library and optimize the reconfiguration strategy of the CNC system to further improve the adaptability of the process and the processing accuracy.

[0033] The mold module feature library also includes the processing priority, assembly relationship and compatible processing equipment model information of each module, which are stored in a standardized format to support the rapid retrieval and updating of module information.

[0034] The machining parameter template library covers standard machining parameters for different materials and machining types. The parameter optimization process is achieved using a genetic algorithm combined with finite element simulation analysis. The optimization variables are a machining parameter vector consisting of cutting speed, feed rate, and depth of cut. A dual-objective fitness function is constructed with the goals of maximizing processing efficiency and minimizing processing error. ,in Let be the processing efficiency function. For machining accuracy function, The weighting coefficients are and satisfy the following conditions: The parameters are optimized through selection, crossover, and mutation iteration operations using a genetic algorithm. Combined with cutting force and cutting temperature data obtained from finite element simulation as constraints, the optimal combination of machining parameters is finally output.

[0035] S3 adopts a modular programming approach, breaking down the machining control logic into tool control sub-modules, axis linkage control sub-modules, and auxiliary equipment control sub-modules. The machining logic can be quickly reassembled through the dynamic combination of sub-modules, and the hardware interface is adapted using a standardized communication protocol.

[0036] In S5, machine vision equipment is used to collect images of the surface of the mold module to obtain data on machining dimensional accuracy and surface roughness. Combined with force sensing equipment to collect cutting force fluctuation data during the machining process, the two types of data are compared with preset accuracy thresholds and force fluctuation thresholds to achieve anomaly judgment. When an anomaly is detected, the parameters are adaptively adjusted according to the severity of the anomaly.

[0037] It also includes S6: processing data traceability and optimization, which unifies the storage of parameter configuration information, equipment operation data and quality inspection data during the processing process, and continuously updates the processing parameter template library and CNC system reconfiguration strategy by analyzing the correlation between processing parameters and processing quality.

[0038] S1 employs a functional structure mapping method, combining the forming, positioning, and guiding functional characteristics of the mold to establish a mapping relationship between function and structure, ensuring that the disassembled standardized modules have the characteristics of independent processing and independent assembly.

[0039] In S3, hardware interface adaptive adaptation automatically completes interface parameter configuration by collecting the communication protocol characteristics and pin definition information of the device interface and matching them with a preset interface feature library.

[0040] When the machining path is executed automatically in S4, the movement speed and acceleration of the path nodes are adjusted according to the machining characteristics of the mold module and the motion characteristics of the equipment.

[0041] In S5, the anomaly classification process selects dimensional deviation, surface defect degree, and cutting force fluctuation as evaluation indicators. Anomalies are classified into different levels according to preset standards, and different levels correspond to different processing strategies.
