Research on Technology of NC Lathing Simulation with Twin-turret

The technology of NC Lathing Simulation with twin-turret is researched. The technology of translating NC program used in SINUMERIK840D system is discussed in detail, with the presentation of compiling NC code to the cutting path information. The simulation of NC lathing with twin-turret is researched on the platform of AutoCAD2004, and the correctness of NC program is checked.
