Study on Simulation of Virtual Processing for Turning-milling Compound NC Machine with ObjectARX

Aiming at optimizing manufacturing process, guaranteeing quality and manufacturing cycle, virtual manufacturing technology imitated the real-time dynamic machining process according to actual cutting conditions, which could realize producibility, manufacturing method and reasonability of process. Based on the mathematic model, interpolating algorithm and motion control method, the simulation software of machining process for multiple-function milling-turning complicated NC machine tools with two rotatory motions was studied and developed, which was achieved using Visual C as developing tool and AutoCAD as simulating platform. The simulation system realized the integration of prototyping in AutoCAD and simulating of CNC effectively, so the real-time virtual machining process driven by NC code was completed. Finally the machining process example was given to demonstrate the feasibility and efficiency.
