| 中文摘要 | 在计算机控制光学表面成形(CCOS)技术中,由于边缘处压力分布的不均匀,会在工件边缘产生边缘效应,边缘效应会严重阻碍面形误差的收敛,边缘效应问题已成为数控加工技术中亟待解决的关键问题之一。针对边缘处压力阶跃分布模型和线性分布模型进行了理论仿真及实验验证,实验结果表明,对于方形工件,在露边量较大(实验中露边量为去除函数束径的1/3)和露边量较小(实验中露边量为去除函数束径的1/24)的情况下,两种模型得到的去除函数结果相差不大,都能够在一定程度上反映出实际结果;当露边量适中(实验中露边量为去除函数束径的1/6)时,线性模型下的去除函数更接近实验结果,阶跃模型在去除函数中心区域与实验结果偏离较大。 |
| 英文摘要 | The edge effect appears at the edge of workpiece as a result of the uneven distribution of pressure in computer controlled optical surfacing (CCOS) and this restricts the fabrication accuracy in practice seriously. The edge effect has become one of the urgent problems of numerical control machining technology. Theoretical simulation and experimental verification are done based on liner pressure distribution model and skin pressure distribution model. The experimental results show that when the distance between the workpiece and the tool borders is relatively large (the distance is 1/3 of aperture of removal function in experiment) or short (the distance is 1/24 of aperture of removal function in experiment). Little difference between removal functions based on both of the models is observed and the effectiveness of the models is proved that when the distance is medium (the distance is 1/6 of aperture of removal function in experiment),the removal function based on linear model is closer to the experimental result and the skin model has a biggr deviation with the experiment result in the central area. |
