本文提出了一种基于模型的方法来识别刀具跳动和估计表面粗糙度从测量切削力。在本文的第一部分中，刀具跳动对切削力变化的影响和对表面粗糙度产生的影响进行了研究。因此，几个影响参数进行了系统的识别和检查。基于理论考虑，推导出刀具跳动、合成工艺力变化和表面粗糙度特性之间的系统关系。通过实验测试，工艺力变化的灵敏度变化的跳动参数进行了研究。在接下来的部分中，基于模型的跳动识别方法，它识别跳动参数准确地从测量的过程力。该方法已被广泛测试，并通过实测跳动参数和加工工件的表面粗糙度特性的相关性进行了验证。在最后一部分中，通过比较基于模型的表面重建的结果与测量的表面形貌的表现所示的方法。
This paper presents a model-based approach for the identification of tool runout and the estimation of surface roughness from measured cutting forces. In the first part of the paper, the effect of tool runout on variations in the cutting forces and the effect on surface roughness generation are studied. Thereby, several influencing parameters are identified and examined systematically. Based on theoretical considerations, systematic relationships between tool runout, resultant process force variations, and surface roughness characteristics are deduced. The sensitivity of process force variation is investigated for varying runout parameters by experimental tests. In the next part, the model-based runout identification method is developed, which identifies runout parameters accurately from the measured process forces. The approach has been tested extensively and was verified by measured runout parameters and the correlation of surface roughness characteristics of the machined workpiece. The performance of the developed approach is demonstrated in the final part by comparing the result of the model-based surface reconstruction with the measured surface topography.
