Conventional milling process remains its importance as it is flexible in cutting dovetails, keyways and slots etc., although Non-traditional machining process are playing major role in machining industry. In other hand Minimum Quantity Lubrication (MQL) refers a little (50-5600ml/hr) lubricant dispensing system which is the substitute for the flood type lubricating system which dispenses 20 L/h of lubricant. In this work, milling experiments are conducted on En-31 material for making die using solid carbide tool and HSS tools under MQL condition. The effect of process parameters such as speed (S), depth of cut (DOC), coolant type (CT), tool material (TM), and amount of coolant dispensed (ACD) on cutting temperature, material removal rate and surface roughness is investigated. A special setup is prepared for regulating the minimum quantity of lubricant. The responses such as Temperature, Material Removal Rate and Surface Roughness are measured and regression models are developed for these responses. Regression models are solved using Particle Swarm Optimization (PSO) technique.

Abstract


Conventional milling process remains its importance as it is flexible in cutting dovetails, keyways and slots etc., although Non-traditional machining process are playing major role in machining industry. In other hand Minimum Quantity Lubrication (MQL) refers a little (50-5600ml/hr) lubricant dispensing system which is the substitute for the flood type lubricating system which dispenses 20 L/h of lubricant. In this work, milling experiments are conducted on En-31 material for making die using solid carbide tool and HSS tools under MQL condition. The effect of process parameters such as speed (S), depth of cut (DOC), coolant type (CT), tool material (TM), and amount of coolant dispensed (ACD) on cutting temperature, material removal rate and surface roughness is investigated. A special setup is prepared for regulating the minimum quantity of lubricant. The responses such as Temperature, Material Removal Rate and Surface Roughness are measured and regression models are developed for these responses. Regression models are solved using Particle Swarm Optimization (PSO) technique.
