There is also practical support for other engineering functions. Digital twins are available for DirectControl-compatible Comau robot arms to enable work in Siemens NX CAM Robotics. The kinematic 3D robot model and the virtual NC kernel Sinumerik VNCK enable sub-programs generated in the CAD-CAM chain to be completely simulated offline. Additional benefits to this enhancement are the reduced footprint due to the elimination of hardware components, lower overall investment, reduced stocking costs for spare parts, and greater availability due to improved MTBF (Mean Time Between Failures).
