对一种由矿物油、半合成和合成切削液组成的乳化液在用涂层硬质合金刀具面铣AISI 8640钢时的切削性能进行了试验研究。为了比较的目的，还进行了干切割。在加工试验过程中，对刀具寿命、功率消耗和表面粗糙度进行了监测。为了研究切削液的冷却能力，在车削AISI 1020钢时，使用工具-工件热电偶法测量切削温度。切削温度最高时产生的加工干，其次是按递减顺序，由应用程序的合成，乳化矿物油和半合成切削液。在加工过程中的功耗方面发现了一个相反的效果。最好的刀具寿命记录加工干时，其次，按递减顺序由合成和半合成切削液的应用。梳状裂纹是切削刀片在加工过程中的主要失效形式。干加工产生的表面光洁度略好于切削液存在下的加工。
An experimental investigation on the performance of an emulsion of mineral oil, semi-synthetic and synthetic cutting fluids when face milling AISI 8640 steel with coated cemented carbide tools were carried out. Dry cutting was also performed for comparison purpose. Tool life, power consumption and surface roughness were monitored during the machining trials. In order to study the cooling ability of the cutting fluids, cutting temperatures were measured during turning of AISI 1020 steels, using the tool–workpiece thermocouple method. The highest cutting temperatures were generated when machining dry, followed in a decreasing order, by the application of the synthetic, emulsion of mineral oil and semi-synthetic cutting fluids. A reverse effect was found in terms of the power consumption during machining. The best tool life was recorded when machining dry, followed, in a decreasing order by the application of synthetic and semi-synthetic cutting fluids. Comb cracking was the major failure mode of the cutting inserts during machining. Dry machining produced slightly better surface finish than machining in the presence of cutting fluid.
