Abstract: According to the requirements such as good human-computer interaction interface and strong sense of immersion and other characteristics of the training system, the real-time 3D construction tools Quest 3D is applied in the development of drilling machine learning system. A development program is put forward for the machine tool virtual simulation training system. The virtual system consists of 3D display module, motion control module, voice module, scene interactive module and sound module. The development cycle of system is shorten and the efficiency of the system is improved through the Quest3D graphics programming. The 3D scene virtual interactive technology is successfully applied in drilling training system.

Key words: 3D scene interaction, teaching and training system, virtual simulation, Quest3D

摘要： 针对培训系统要求人机交互界面好以及沉浸感强等特点，在钻床教学系统开发中采用实时3D建构工具Quest3D，提出了一种针对钻床教学培训的虚拟现实系统的开发方案，将虚拟现实系统分为三维显示模块，运动控制模块，场景交互模块和场景声控模块等，通过Quest3D的图形编程使得整个系统开发周期缩短，运行效率提高。成功将三维场景虚拟交互技术运用于钻床教学培训系统中。
