Abstract With the extensive CNC machine tool applications, the number of CNC machine simulation software is growing, but the software for NC machining process simulation system is small .The function VERIC -UT present in this is the most perfect. VERICUT applied to NC teaching can greatly help students understanding NC machining processing. 

This paper used simulation software VERICUT to develop virtual simulation system by virtual machine modeling. First, this study introduced virtual CNC machining simulation technology, simulation software VERICUT and the process of building a CNC simulation platform for VERICUT. According to principles and characteristics of system design, then determine the overall design. And then, in the process of detailed design, through VERICUT to build a virtual machine, to complete the definition of the control system and related subroutine. Finally, conduct the tool path simulation processing by the application of VERICUT's virtual simulation processing system, and check the collision and interference in the product processing, subsequently modify the NC program to achieve the purpose of improving the optimization of the NC program.
