摘要

本文分析了微观几何参数，特别是切削刃圆角半径、边缘宽度和前角对 7075 合金铣削表面粗糙度的影响。该研究以一组 243 次切削试验为基础，共使用了 27 台铣床，每台铣床都采用了独特的几何形状、进给量和径向进给组合。建立了粗糙度参数的实验数学模型。研究结果表明，虽然切削刃圆角半径对表面粗糙度的影响是非线性和非单调的，但边缘宽度的影响是单调的，并且是影响粗糙度的最重要因素。

Redefinition of precision in finishing milling: Exploring the influence of tool margin and edge micro-radius on surface roughness

This article presents an analysis of microgeometry parameters, specifically the radius of cutting edge rounding, margin width, and rake angle influence on surface roughness in the milling of 7075 alloy. The study is underpinned by a set of 243 cutting tests conducted using 27 mills, each with a unique combination of geometry, feed, and radial infeed. Experimental mathematical models of the roughness parameters were developed. The findings reveal that while the influence of the cutting edge rounding radius on surface roughness is nonlinear and non-monotonic, the margin width has a monotonic effect and is the most significant factor impacting roughness.
