Abstract

In recent years, NC machining simulation technology has been widely used in manufacturing, it is one of the key technologies of CAD / CAM technology, and the integrated application of advanced technology which including NC technology and computer simulation technology. And as the leader in virtual NC machining software, VERICUT software can replace the traditional cutting experiment components. Accuracy to simulate the entire machining process and verify NC program, it can remove programming errors and improve cutting efficiency.

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.

Keywords: NC machining; Virtual machine; Simulation processing; Tool path simulation; Subroutine
