中文摘要：为揭示立铣刀磨损、破损机理,本文采用课题组自主研发的嵌入式刀柄系统,对难加工金属AISI 304不锈钢进行了不同冷却方式、铣刀转速和铣刀直径等变切削参数的测温实验研究,结果表明:主轴转速10 000 r/min时,由干式切削变为湿式切削最高切削温度可下降246℃;在相同刀孔比(1∶1.5)干式铣削时,?12 mm铣刀比?20 mm铣刀测温点最高温度高500℃;湿式切削加工质量较高,圆柱度均小于0.02 mm,尤其是在深孔铣削加工时,内冷铣削优势更趋明显,为高速内冷铣削方式的推广应用提供参考。

外文摘要：In order to reveal the wear mechanism and breakage mechanism of the end milling cutter, a self-developed embedded temperature monitoring tool holder is adopted. The temperature measurement experiments of the difficult to machine AISI 304 stainless steel with different cooling methods, cutting speeds and cutter diameters were carried out. The results show that the maximum temperature decreases 246 ℃, from dry milling to cool milling at 10 000 r/min. At the same milling cutter and borehole ratio(1∶1.5) and 6 000 r/min, the maximum temperature is higher 500 ℃ with ?12 mm milling cutter than that with ?20 mm milling cutter. The advantages of the cool milling include the higher quality of the machined borehole surface and the cylindricity is less than 0.02 mm. The advantage of internal cool milling is more obvious in deep-hole milling. The results provide a reference for promoting and applying the high speed internal cooling method.
