本文提出了一种基于模型的仿真系统，用于分析超精密金刚石车削中的表面粗糙度生成。该系统基于表面粗糙度模型，该模型考虑了刀具几何形状、工艺参数和相关刀具工作振动的影响。它是通过一系列切削实验来评估的。结果表明，该系统能够很好地预测各种切削条件下金刚石车削表面的表面粗糙度轮廓和粗糙度参数。通过使用频谱分析技术，该系统还可以帮助分析振动对工件表面质量的影响并诊断机器故障。文中还讨论了该系统在流程优化中的潜在应用。 (C) 2000 Elsevier Science Ltd. 保留所有权利。
In this paper, a model-based simulation system is presented for the analysis of surface roughness generation in ultra-precision diamond turning. The system is based on a surface roughness model which takes into account the effect of tool geometry, process parameters and relative tool-work vibration. It is evaluated through a series of cutting experiments. The results indicate that the system can predict well the surface roughness profile and the roughness parameters of a diamond turned surface under various cutting conditions. With the use of the spectrum analysis techniques, the system can also help to analyze the effect of vibration on the surface quality of workpiece and to diagnose the machine faults. The potential application of the system in process optimization is also discussed in the text. (C) 2000 Elsevier Science Ltd. All rights reserved.
