摘要
在超精密飞切加工中,加工表面的三维形貌特征主要包括粗糙度、波纹度和面形,不同的三维形貌特征受到不同表面质量因素的影响.为了研究不同因素对表面质量的影响情况,首先对超精密飞切加工过程中的影响因素进行了分析;然后,基于刀刃复印的原则,建立了一种超精密飞切加工表面三维形貌的仿真模型;最后,基于该模型,对工艺参数及刀具-工件的相对振动等主要因素的影响规律进行了分析,获得了加工表面主要空间频率与相对振动频率之间的关系.
In ultra-precision flycutting,the 3D topography of the processed surface mainly includes roughness,waviness and surface shape.These characteristics are affected by different surface quality factors.In order to study the influence of different factors on the surface quality,the influence factors of ultra-precision flycutting were analyzed.Then,based on the principle of blade copying,a simulation model of 3D shape of ultra-precision flying cutting surface was established.Finally,the influence law of main factors such as process parameters and relative vibration of cutler-work was analyzed using this model,and the relationship between the main spatial frequencies of the processed surface and the relative vibration frequencies was obtained.
