最近的研究表明，整个CNC虚拟链作为一个潜在的战略，以预测轮廓误差，但由于CNC制造商不透露有关的轨迹的生成信息，它变得难以复制的轮廓误差模拟商业机器。在本文中，一种混合的方法，可以简化监控和仿真任务，提供一个侵入性较低的战略接口的商业机床。所开发的系统利用机床CNC生成的定位设定点，并将其用作输入数据来模拟刀具中心点（TCP）运动，并预览预期的轮廓误差，同时考虑控制系统和进给驱动器的行为。总之，所提出的方法增加了以前的虚拟数控系统的发展，因为监测数控系统的设定点直接送入仿真模型。使用开发的混合动力系统在商业机床显示3 μ m之间的最大偏差的观察和模拟的轮廓误差，因此显示其足以预览商业机床的轮廓误差。
Recent studies show the entire CNC virtualization chain as a potential strategy to predict the contour error, but since the CNC manufacturers do not disclose information about the trajectories' generation, it becomes difficult to replicate contouring error simulation on commercial machines. In this paper, a hybrid approach allows simplifying the monitoring and simulation tasks by providing a less intrusive strategy to interface commercial machine tools. The developed system takes advantage from the positioning set points generated by the machine CNC and uses them as input data to simulate the tool-center point (TCP) movements and to preview the expected contour error, considering also the behavior of the control system and feed drives. In summary, the proposed approach adds on previous virtual CNC developments since the monitored CNC set points are fed directly into the simulation model. The use of the developed hybrid system in commercial machine tools shows a maximum deviation of 3 mu m between the observed and the simulated contour error, showing therefore its adequacy to preview the contour error of commercial machine tools.
