An Investigation on Green Machining: Cutting Process Characteristics of Organic Metalworking Fluid

摘要

This paper compares the cutting process characteristics of organic and inorganic coolant for milling process.RBD(refined,bleached & deodorized) palm olein,refined canola and soy bean oil were selected as based oil for soluble mixture(organic) while Jetkool SC95 as inorganic metalworking fluid (MWF).Throughout the research,carbide coated cutting tool and JIS SS400 mild steel are used with various feed rate,depth of cut and fixed spindle speed to determine the cutting temperature,forces and also surface roughness.Heat capacity,pH and tool wear assessment are carried out as well with same material.From the research,cutting temperature,cutting force and surface roughness are proportional to the feed rate and depth of cut.The MWFs pH level also drops after cutting process.Each MWFs showing their different strength on different assessments,overall from the results obtained,palm oil has a high potential to be marketed as organic MWF.
