Turning operation is one of the most used operations at various industries and obtaining desired machined surface quality is one of the important concerns of researchers. In this investigation the effects of using copper oxide nano-fluid as compared with conventional fluid (soluble oil) as coolant and lubricant on surface integrity of machined surface of heat treated cold work tool steel (AISI O1) as workpiece has been investigated. So cutting speed and tool’s feed rate have been considered as input variables and surface roughness, created white layer thickness and density of generated surface cracks have been considered as output parameters and regarding full factorial method of design of experiments a set of experiments for each kind of coolants has been designed and performed. The results have been shown that adding copper oxide nano particles as equal as 1% in volume to deionized water as base fluid decreases the amount of machined surface roughness as compared with using soluble oil. Also using the prepared copper oxide nano-fluid decreases the amount of created white layer thickness and density of generated surface cracks on machined surfaces as compared with soluble oil.

Abstract


Turning operation is one of the most used operations at various industries and obtaining desired machined surface quality is one of the important concerns of researchers. In this investigation the effects of using copper oxide nano-fluid as compared with conventional fluid (soluble oil) as coolant and lubricant on surface integrity of machined surface of heat treated cold work tool steel (AISI O1) as workpiece has been investigated. So cutting speed and tool’s feed rate have been considered as input variables and surface roughness, created white layer thickness and density of generated surface cracks have been considered as output parameters and regarding full factorial method of design of experiments a set of experiments for each kind of coolants has been designed and performed. The results have been shown that adding copper oxide nano particles as equal as 1% in volume to deionized water as base fluid decreases the amount of machined surface roughness as compared with using soluble oil. Also using the prepared copper oxide nano-fluid decreases the amount of created white layer thickness and density of generated surface cracks on machined surfaces as compared with soluble oil.
