基于ARM的全软件开放式数控系统设计

Design of all-software open CNC based on ARM

目前,常见的开放式数控系统多为PC嵌入NC的架构。针对该类数控系统的运动控制模块是封闭结构,系统整体开放程度不高的缺点,提出一种基于ARM+CPLD架构的全软件开放式数控系统设计方法。通过对该设计进行软硬件实现,用户不仅可以定制人机交互界面,还可以制定系统的运动控制策略,实现较高的开放性。在试验系统上进行数控加工试验,结果显示,全软件开放式数控系统可以有效地完成数控加工任务,加工的精确度较高。

At present,the architecture of the common open CNC is the one of PC-embedding NC.To overcome the system＇s poor degree of opening due to the closed architecture of NC motion control module an all-software open CNC design method based on ARM＋CPLD architecture is proposed.Through realizing this design method,users can establish not only human-computer interaction interfaces,but also systematic strategy of motion control to reach a higher degree of system opening.The results realized in the experimental system indicate that an all-software open CNC can process effectively with a higher precision of processing.
