摘要:

针对数控机床能量源多、能量消耗动态变化复杂的特点,提出了一种基于业务流程模型和符号(Business process model and notation, BPMN)的数控机床多源动态能耗建模方法。依据数控机床不同子系统的功率特性,将其划分为时变能耗单元和非时变能耗单元,分析了其工作状态及耦合关系对数控机床能耗的影响;基于BPMN2.0规范,构建了能耗单元工作状态BPMN流程模型和BPMN耦合模型,提出了能耗单元工作状态能耗数据及耦合关系时序数据与BPMN模型的数据集成方法,构建了数控机床能耗多源动态特性模型。以某数控铣床加工过程为例验证了所述模型及方法的有效性。

Abstract:

Aiming at the complex multi-source and dynamic energy characteristics of CNC machining tools, a modeling methodology is proposed based on BPMN (business process model and notation). Firstly, the energy sub-systems of machining tools are divided into time-varying and non time-varying energy units with their power attributes, and the energy consumption of the execution process and the coupling relationship of their work ststus are also studied respectively. Secondly, an execution process model and a coupling relationship model are established with the BPMN2.0 specification, and an integrated approach with the energy data and time series data of this model are also proposed. Finally, a case study of a process with milling tool is given to verify the effectiveness of the proposed model and approach.
