Abstract:The supporting technologies of five-axis CNC machine tools are establishing virtual machining platform, correcting NC program and process simulation and optimization, which can make the efficient machining technology come true. Taking non-orthogonal 5-axis CNC machine tools DMC70ev as the object, NC machining simulation platform based on the VERICUT was constructed. Taking surface machining for example, the optical design mathematical model of the constant volume removal rate and constant chip thickness optimum method was established and the tool path optimization was carried out. The research result has realized five-axis process simulation of NC machining and the verification of NC program accuracy, which reduces tool wear, improves the processing efficiency and quality, the application level, quality of NC machining technology for enterprises, and will promote the development of modern manufacturing technology.
