| 摘 要： | 从理论上建立了离子束抛光中切向定位误差对加工残差影响的模型,分析发现了该误差对加工残差的影响与面形的梯度有关.特别地分析了定位误差对不同频率成份误差的影响规律,并进行了仿真研究,验证了残差大小与相对定位误差成正比这一结论.同时利用相对定位误差对残差影响理论,评价了KDIBF1600离子束抛光机的设计精度,机床设计精度满...

| Abstract: | On the basis of the modeling of the tangential positioning error effect on the processing residual errors,it is found that the effect is related with the gradient of the optical surface.Particularly,the tangential positioning error effect on different frequencies is analyzed and simulated to verify that the residual error is proportional to the relative positioning error.The KDIBF1600 machine error model is established to get the value of the tangential positioning error,and the design accuracy of the machi... |
