The Optimization of Cutting Parameters When High Speed Cutting Thin-Walled Workpieces of Hardened Steel Using Micro-End Mill

以正交试验为基础,采用小直径铣刀高速铣削淬硬钢薄壁件,研究不同的切削参数对淬硬钢薄壁件高速铣削时的径向切削力、振动以及工件表面粗糙度的影响并对切削参数进行优化。首先将研究目标化为衡量产品质量稳定性的SN比;然后采用主成分分析法将多目标质量特征转化为单目标质量特征并结合方差分析对切削参数进行优化,不仅分析了切削参数对综合质量目标影响的显著性,而且得出了较为合理的切削参数,对淬硬钢薄壁件的高速铣削具有一定的指导意义。

Based on the orthogonal experiments ,using micro-diameter tool cut thin-walled parts of hardened steel in high-speed to research the effects of different cutting parameters on the radial cutting force,vibration,and surface roughness and optimize the cutting parameters.Firstly making the researching goal as measured SN ratio of the stability of product quality,then using principal component analysis to make the multi-objective quality characteristics into a single objective quality characteristics combined with analysis of variance to optimize the cutting parameters which not only analyze the significant impacts of cutting parameters on comprehensive quality but also obtain more reasonable cutting parameters and it can be a certain guiding significance for cutting thin-walled parts of hardened steel with high speed.
