切削液在机械加工中有着广泛的应用。然而，它们带来了几个健康和环境问题。文献报道了一些关于植物基切削液的工作，但这些工作的主要焦点是用植物油取代矿物油，而乳化剂往往是所有这些问题的根本原因，从未被取代。本工作试图用植物性乳化剂(芝麻油和椰子乳化剂)来替代矿物油和石油基乳化剂，并生产一种新型的可持续切削液。在加工美国钢铁协会(AISI)1040钢时，将所配制的切削液与普通切削液进行了比较。结果表明，植物乳化剂含量为10%的复合切削液在切削温度、刀具磨损和表面粗糙度等方面与普通切削液具有相似的性能。10%椰子乳化液的性能优于其他添加椰子乳化剂的液体。然而，使用常规切削液时，切削力较小。配制的润滑液可用于切削力低但切割温度高的情况，如更高速度的加工。这项工作的主要贡献是除了使用植物油外，还用一种环保的替代品取代了常规的石油乳化剂。
Cutting fluids are widely used in machining. However they pose several health and environmental issues. Several works on vegetable-based cutting fluids have been reported in literature but the prime focus of these works was the replacement of mineral oil with vegetable oil while the emulsifier, which is often the root-cause of all these issues, was never replaced. The present work is an attempt to replace both the mineral oil and petroleum-based emulsifier with vegetable-based alternatives (sesame oil and coconut based emulsifier) and produce a new class of sustainable cutting fluids. The formulated cutting fluids were compared with regular cutting fluid while machining American Iron and Steel Institute (AISI) 1040 steel. The findings show that the formulated fluid with 10% vegetable emulsifier content exhibits a performance similar to the regular cutting fluid in terms of cutting temperatures, tool wear and surface roughness. The performance of the 10% coconut emulsifier fluid was better than other fluids with coconut emulsifier. However, cutting forces were less when the regular cutting fluid was used. The formulated fluids can be used in situations with low cutting forces but high cutting temperatures, like machining at higher speeds. The major contribution of the work is the replacement of regular petroleum-based emulsifier with an eco-friendly alternative, in addition to using vegetable oil.
