Abstract
Recently, difficult-to-cut alloys have been developed to cope with the demands of today’s manufacturing requests. They are characterized by their superior mechanical properties like high strength and high resistivity to corrosion and oxidation which make them a prior candidate to be applied in extremely hard environments. However, these alloys face some problems during their machining process. Their machine requires high cutting forces, and there exists high friction among the cutting region. High heat is generated at the machining zone. These factors dramatically affect the quality of the produced machined surface and reduce the tool life of the cutting tools. To overcome these problems during the machining process, it is highly recommended to apply cutting fluid to cool the cutting area and help to lubricate the contacting surfaces among the tool, chip, and workpiece. However, on the other hand, cutting fluid sometimes causes many harmful health hazards to the machinist who is in direct contact with it. To cope with the environmental concerns, the cutting fluid applied should be chosen properly in order not to cause any harmful consequences to the surrounding environment when being deposited of. So, the new trends in the application of cutting fluids have been directed at decreasing the consumption of cutting fluids as much as possible. The minimum quantity lubrication technique has been utilized in this area and has shown excellent results during the machining of many alloys. It is the technique in which the fluid is mixed with compressed air and is applied at a rate not exceeding 100 ml/hr. In our study, we are concerned with studying the application of minimum quantity lubrication technique during the turning process of one of the most widely common difficult-to-cut steel alloys which is AISI 304 stainless steel. To cope with the environmental concerns, the cutting fluid utilized in our study was vegetable cotton seed oil. We hope to obtain good surface integrity and improved tool life during the turning process of AISI 304 stainless steel alloy under the minimum quantity lubricant technique via vegetable-based oil.
