【摘要】 针对原有数控机床教学中存在数据孤立、工艺设计与质量管控脱节等问题，构建基于以太网B/S架构的DNC-MES-SPC集成的数控机床教学平台。DNC(分布式数控)实现设备互联互通、加工程序统一管理及机床运行数据实时采集；MES(制造执行系统)整合多源数据，驱动生产排程、工艺设计与优化调整；SPC(统计过程控制)对测量数据进行分析，判定过程异常。MES基于SPC的分析结果生成工艺优化方案，并通过DNC下达执行，形成“数据感知—分析决策—工艺迭代”的闭环管控。平台贯穿工艺设计、加工执行、质量优化实践教学环节，推动工程训练向数字化、智能化模式转型。更多还原

【Abstract】 In response to the problems of isolated data, disconnection between process control and quality control in traditional CNC machine tool teaching, an integrated teaching platform, DNC-MES-SPC, based on Ethernet architecture is designed and constructed. DNC(distributed numerical control) enables interconnection of devices, unifi ed management of machining programs, and real-time collection of machine tool operation data. MES(manufacturing execution system) integrates multi-source data to drive production scheduling, process is-suance, and optimization adjustments. SPC(statistical process control) analyzes measurement data to identify process anomalies. Based on the analysis results of SPC, MES generates process optimization plans and issues execution commands through DNC, forming a closed-loop control of "data perception-analysis and deci-sion-making-process iteration". The platform covers practical teaching links of process design, machining execu-tion, and quality optimization, promoting the transformation of engineering training towards a digital and intelligent model.更多还原
