【摘要】 随着数控技术的广泛应用，为了保证数控加工程序的正确性和高效的培训操作人员，非常有必要开发一套具有较高真实感的数控加工仿真培训系统。 本文重点论述了数控加工仿真培训系统的几个组成部分的关键技术： ● 三维图形仿真技术 在对基于图像空间的Dexel模型和基于物体空间的CSG和八叉树模型讨论的基础上，重点讨论了作者开发的数控加工仿真培训系统所用的离散模型、切削过程的布尔运算和实时显示技术。 ● 系统功能仿真技术 在对数控机床结构讨论的基础上，重点讨论了数控代码解译器的实现技术、刀具补偿和插补算法。 ● 面向对象的软件设计技术 在对科德的面向对象方法讨论的基础上，介绍了数控加工仿真培训系统的分析和设计，并介绍了相关的skin和多线程技术。 在上述技术研究的基础上，作者成功开发了一套数控车削加工仿真培训系统，该系统具有功能齐全，使用方便等特点。更多还原

【Abstract】 With the extensive application of numerical control techniques, it is indispensable to develop a numerical control machining simulation training system ( NCMSTS) with high 3D effect to guarantee the validity of NC code and training NC operators with high efficiency.Several key techniques of NCMSTS is discussed in the thesis:3D Graphic Simulation TechniqueOn the ground of the discussion of Dexel model based on image space and CSG and octree models based on object space , the discrete model, Boolean operation of cutting process and real time display technique used in NCMSTS are discussed.Simulation Technique of NC System FunctionsOn the base of the discussion of the construction of NC machine, it lays the emphasis on the implementation technique of NC code interpreter, tool compensation and interpolation algorithm.Object-Oriented Software Design TechniqueOn the base of Coad’s object-oriented method, it introduces the analysis and design of NCMSTS, and some related skin and multi-thread technique.With the technique research mentioned above, a numerical turning simulation training system (NCMSTS) is developed by author successfully. It almost include all functions of NC machining and can be used very conveniently.更多还原
