本文提出了一种基于模型的方法来监测铣削操作的形状偏差。为了检测铣削加工过程中工件发生的形状偏差，提出了不同类型的过程模型，并讨论了它们在制造质量监控中的应用。因此，提出了一种基于模型的系统，用于基于测量的切削力的形状偏差的监测。为了将切削力转化为形状偏差，设计了刀具变形模型和材料去除模型，并将其应用于监控系统中。所提出的基于模型的监测方法提供了准确的质量信息，如几何形状偏差，可以根据几何公差进行监测，提供了制造过程的质量监测。通过比较测量和重建的形状轮廓，从测量的切削力的形状偏差的重建实验验证。
This paper presents a model-based approach for monitoring of shape deviations for milling operations. In order to detect occurring shape deviations of the machined workpiece during the milling process, different kinds of process models are presented and discussed for their application on manufacturing quality monitoring. Thereby, a model-based system was presented for the monitoring of shape deviations based on measured cutting forces. For the transformation of cutting forces into shape deviations, a tool deflection model and material removal model were designed and applied to a monitoring system. The presented model-based monitoring approach delivers accurate quality information, like geometric shape deviations, which can be monitored against geometric tolerances, providing a quality monitoring of manufacturing processes. The reconstruction of shape deviations from measured cutting forces is verified experimentally by comparing measured and reconstructed shape contours.
