ABSTRACT
Due to their adequate lubricating characteristics on both the workpiece and the cutting tools, mineral oils have traditionally been used as the conventional source of cutting fluids in the machining of a variety of metals and alloys. However, employing these oils as lubricants in the majority of modern applications comes with certain difficulties. Recent times have seen a shift in emphasis towards bio-based lubricants due to environmental concerns. Plant oil is converted into bio lubricants using a variety of chemical modifying processes. Bio-lubricants are an excellent substitute for mineral-based oils since vegetable oils are more lubricating and environmentally beneficial. In this regard, an experiment is carried out to determine the efficiency of various bio-based metal cutting fluids (MCF), which are crucial to the machining process and have an impact on it. The primary goal of this study is to demonstrate that bio coolant is a real substitute for petroleum and mineral oil lubricants. The efficacy of the bio coolant is evaluated in turning and drilling operations. An improved results are observed in the tool tip temperature and specimen surface finish in both drilling and turning operations.
