但是五轴联动数控机床系统价格十分昂贵，加之在数控程序编制上存在着很大困难，因而如何使得五轴加工得以“平民”化应用，已经成为机床制造业的一个热点问题。本文从虚拟机床技术开发，探讨其在五轴加工的应用，实现仿真加工，优化数控程序，从而提升加工质量、提高加工效率、降低加工成本。

2、虚拟机床应用的优势

  数控加工最终的好坏取决于以下5个因数中的短板：数控机床、控制器、刀具、数控编程和CAM软件。虚拟机床的应用正好可以解决以上短板问题，采用虚拟机床存在以下优点：

2.1 真实性

  传统CAM软件驱动的标准模拟仿真是一种不完整的近似运动模拟，不能避免实际加工过程中的过切与撞刀。虚拟机床技术采用内置CNC控制器驱动的加工模拟仿真是真实可靠的，可以把加工中的各种风险（撞刀、过切等）降为零。

2.2 先进性

  虚拟机床不仅可以仿真传统的车床、铣床、加工中心，而且可以仿真车铣复合和多轴联动机床。目前，西门子公司的虚拟机床对于不同CNC控制系统的特殊加工指令及FMS柔性制造系统可以进行仿真。

2.3 互操作性

  虚拟机床不仅提供三维数字机床，而且包含虚拟控制面板，提供和车间环境一样的虚拟实训环境。应用虚拟机床，可以实现学生的大量仿真与真实机床没有区别。这对于目前企业紧缺的中高端数控人才，是一个很好的培训解决方案，使复杂机床的编程及加工操作培训费用降低50%，从且可以大大地降低培训成本。
