摘　　要：对刀位点数据进行实时、全交互的加工仿真是高档数控系统的基本功能需求。针对该需求,提出一种基于可视化工具箱(VTK)的数控加工线框仿真组件实现技术。通过动态插入刀位点构造并维护一个VTK标准数据集,利用VTK功能全面、性能优异的三维数据可视化引擎进行VTK数据管道的显示和交互。采用该技术的ActiveX组件已成功应用于基于工业以太网的新一代数控系统中。It is a basic requirement for modern numeric control system to visualize the cutter location points immediately and interactively. Aiming at the problem, this paper proposes a implementation technology of numeric control machining wire-flame simulation system based on Visualization ToolKit（VTK）. A normal VTK dataset is generated and maintained dynamically by inserting cutter location coordinates. A special VTK data pipeline routine is carried out to display and perform interaction operation, it fully utilizes the excellent 3D visualization engine of VTK. The ActiveX using that technology is successfully applied in a new generation of Ethernet based numeric control system.
