【摘要】：砂岩装饰品已逐渐走进人们的生活,提高砂岩加工表面质量已备受关注。利用正交试验,研究PVD涂层刀具高速铣削砂岩的切削速度、进给速度及切削深度对加工表面粗糙度的影响。分析了表面粗糙度随不同切削参数的变化规律:随着进给速度与切削深度的增加,表面粗糙度值变大,随着切削速度的增加,表面粗糙度值减小,当切削速度由3000r/min提高到12000r/min时,表面粗糙度值由4.98μm减小到3.64μm。建立了表面粗糙度的回归预测模型,经F检验具有较高的显著性,为实际生产加工砂岩制品提供了一定理论依据与参考价值。
[Abstract]:Sandstone ornaments have gradually come into people's lives, and the improvement of sandstone surface quality has attracted much attention. The effects of cutting speed, feed speed and cutting depth on the surface roughness of high speed milling sandstone with PVD coated tool were studied by orthogonal test. The variation of surface roughness with different cutting parameters is analyzed. With the increase of feed speed and cutting depth, the surface roughness value becomes larger, and with the increase of cutting speed, the surface roughness value decreases. When the cutting speed is increased from 3000r/min to 12000r/min, The surface roughness decreased from 4.98 渭 m to 3.64 渭 m. The regression prediction model of surface roughness is established. The F test has a high significance and provides a certain theoretical basis and reference value for the actual production and processing of sandstone products.
