摘要/Abstract

摘要： 冷却方式在切削难加工材料的过程中扮演了一个非常重要的角色，例如加工钛合金.本文对一种称谓“OoW”的冷却方式在AlCrN/AlTiSiN涂层立铣刀加工钛合金Ti-6Al-4V过程中对刀具的切削特性的影响进行了研究.在不同水含量（1.5，3.0，4.5 L/h）润滑油含量（20，30，50 mL/h）和润滑剂类型（1000-20、2000-30合成酯、2000-10脂肪醇）的条件下，对刀具的磨损、切削力、切削温度、工件的表面粗糙度以及切屑形态进行了研究.实验结果表明，低水量（1.5L/h）能显著地提高刀具的切削特性.然而，润滑剂含量以及类型对刀具的切削特性影响不明显.同时，OoW冷却方式与干切、湿切、低温微量润滑3种润滑方式进行了对比.结果显示低含水量（1.5L/h） OoW冷却方式比其他3种冷却方式对刀具磨损最小、磨损率最低，同时工件的表面粗糙度也最小.这归因于OoW冷却方式融合了水的优良冷却特性和油的高润滑性.此外，冷却方式和冷却参数对切屑的形态有影响.

Abstract: The cooling strategy plays an important role during the machining of difficult-to-cut materials, such as titanium alloys. In this work, an oils on water (OoW) cooling was investigated with coated carbide end mills with AlCrN/AlTiSiN coatings during the Ti-6Al-4V alloy machining. Through various amounts of water (1.5, 3 and 4.5 L/h), oil (20, 30, 50 mL/h) and lubricant types (1000-20 and 2000-30 synthetic ester, 2000-10 fatty alcohol), tool wear, cutting force, cutting temperature, the surface roughness and chip morphologies were observed under the OoW cooling condition. The cutting performances were compared for all conditions, where a low amount of water (1.5 L/h) demonstrated significant improvement in the cutting performances of the coated tools, while the lubricants and amount of oil had low effects. The effect of OoW cooling on the cutting performance was also studied in comparison with dry cutting, flood cutting and minimal quantity lubrication with cryogenic air (CAMQL) cooling. For the optimized water amount at 1.5 L/h, the lower tool wear and surface roughness of the machined surface were observed. The wear rate of the coated tool through OoW cooling was also significantly slower compared to dry cutting, flood cutting and CAMQL cooling. The reason for improvement under the OoW cooling condition originated from the improved cooling effect compared to other cooling strategies, due to the excellent combined cooling effect of water and oil lubrication through OoW cooling. In addition, the chip morphology was also observed to be affected by both the cooling strategy and cooling parameters.
