摘要
研究了干式高速铣削对JIS SKD61硬质钢表面质量的影响,并与常规冷却液法进行了比较。这项研究是在Super MC 500高速数控铣床上进行的,该铣床采用日立涂层碳化物,直径为20mm。高速切削参数如切削速度V、切削深度t和主轴转速S被视为变量。这个实验是根据田口的L9设计的。表面质量,包括Ra和Rq,使用Mitutoyo Surftest SV-210进行测量。通过对干燥流体和冷却流体条件的回归分析,建立了表面粗糙度平均值的数学回归模型。通过方差分析得到所选择的高速铣削参数和相应的Ra、Rq值。湿、干铣削表面质量对切削深度、进给速度和切削速度的灰色关联得分分别为0.7527、0.7869、0.6302和0.8167、0.7199、0.6040。结果表明:冷却液高速铣削淬硬钢时,进给速度对表面质量的影响最大,而高速干铣削时,切削深度对表面质量的影响最大。
Surface Finish Comparison of Dry and Coolant Fluid High-Speed Milling of JIS SDK61 Mould Steel
This paper investigates the influence of dry high-speed milling on the surface quality of JIS SKD61 hard steel, compared to the conventional coolant fluid method. This research was conducted in a Super MC 500 high-speed CNC milling machine with a Hitachi coated carbide 20mm in diameter. High-speed cutting parameters such as cutting speed V, cutting depth t, and spindle speed S were considered as variants. The experiment was designed based on Taguchi's L9. Surface quality, including Ra and Rq, was measured using the Mitutoyo Surftest SV-210. A mathematical regression model was found for the average values of surface roughness through regression analysis for dry and coolant fluid conditions. The chosen high-speed milling parameters and the respective Ra and Rq values were obtained by ANOVA. The grey relation scores for wet and dry milling surface quality for cut depth, feed rate, and cutting speed were 0.7527, 0.7869, 0.6302, and 0.8167, 0.7199, 0.6040, respectively. The results showed that the feed rate had the greatest influence on the surface quality during the high-speed coolant milling of hardened steel, while the depth of the cut had the greatest influence on the surface quality during the high-speed dry milling process.
