基于BPMN2.0的数控机床主传动系统动态能耗建模
|
摘要
选取数控机床的主要耗能子系统即主传动系统进行研究,针对其加工过程中能量消耗动态变化且难以规范化描述的特点,通过主传动系统能量消耗动态性的分析,提出了一种基于业务流程建模规范BPMN2. 0的数控机床主传动系统动态能耗建模方法。该方法利用BPMN2. 0的符号和语义对主传动系统不同能耗单元的执行流程、配合关系进行描述,并利用数据关联集成建立的业务流程建模规范(BPMN)能耗模型,实现了制造过程中数控机床主传动系统能耗动态性的图形化表达与能耗计算。最后,以某数控铣床加工过程为例,对所述模型及方法进行了应用,验证了其有效性与准确性。
There is enormous energy consumption of machine tools with the popularity of Computer Numerical Control( CNC) machine tools in China. As the dominating energy consumption subsystem of CNC machine tools,the main transmission system was studied. By analyzing energy consumption characteristic of main transmission system,a method of modeling energy consumption of main transmission system in CNC machine tools was proposed based on the criteria of BPMN2. 0. Using the notation and semantics of BPMN2. 0,the execution flow,cooperative relationship and data association of energy-consuming units of the main transmission system in CNC machine tools were expressed graphically and energy consumption of main transmission system was calculated by this method. Finally,one processing of CNC milling machine was put forward to validate the effectiveness and accuracy of this modeling method.
