摘要: 机床加工间歇期间的状态控制是提升机床节能效果的重要途径之一。针对当前未充分考虑随机任务情况对机床间歇状态控制的影响,导致机床在固定的节能控制策略下节能效果差的问题,提出一种随机任务驱动下机床间歇状态的动态节能控制方法。首先,分析随机任务下机床加工间歇的能耗模式,设计多种随机任务驱动下的机床间歇状态动态节能控制策略与切换机制;在此基础上,根据分析影响状态控制的关键因素建立随机任务加工环境信息样本集,构建堆栈去噪自编码节能控制模型,提取随机任务加工环境信息与机床节能控制策略紧密相关的深层特征,并作为SoftMax分类器的输入进行节能控制策略选择,以建立随机任务与机床节能控制策略的复杂映射关系,实现机床间歇状态的动态控制。最后以工件随机到达、新订单插入等随机任务为例进行验证。结果表明,所提方法能够实现机床间歇状态在随机任务引起的加工间歇长短改变情况下,节能、高效、准确地调整控制策略。

Abstract: The state control of machine tools during machining intervals is one of the important ways to improve the energy saving effect of machine tools. In view of the current problem that the impact of random tasks on the intermittent state control of machine tools is not fully considered, resulting in poor energy-saving effect of machine tools under fixed energy-saving control strategies, a dynamic energy-saving control method for intermittent state of machine tools driven by random tasks is proposed. First, the energy consumption patterns of machine tool intermittent processing under random tasks are analyzed, and various dynamic energy-saving control strategies and switching mechanisms for machine tool intermittent states driven by random tasks are designed; on this basis, a sample set of random task processing environment information is established based on the analysis of key factors affecting state control, a stacked denoising auto-encoder energy-saving control model is constructed, and the deep features of random task processing environment information closely related to machine tool energy-saving control strategies are extracted. The deep features closely related to the machine tool energy-saving control strategy are extracted and used as the input of SoftMax classifier for energy-saving control strategy selection, so as to a complex mapping relationship between the random task and the machine tool energy-saving control strategy is established and realize the dynamic control of the intermittent state of the machine tool. Finally, random tasks such as random arrival of workpieces and insertion of new orders are used as examples for validation. The results show that the proposed method is able to realize the energy-saving, efficient and accurate adjustment of the control strategy of the machine tool intermittent state under the change of the machining interval length caused by the random task.
