Abstract

 

 

The most crucial demand in manufacturing industry is to improve productivity and efficiency of the processes. Cooling strategies play a significant role in determining the quality and cost of manufactured parts in machining operations. The present study examines machinability under new and alternative cooling methods in turning, milling and turn-milling operations. It begins with an investigation of tool wear, surface finish, cutting forces and chip formation in turning of Ti6Al4V and Inconel 718 using a new cryogenic cooling approach, followed by a new assessment to enhance efficiency of cryogenic cooling in orthogonal turn-milling of Inconel 718 and steel 1050. Finally, thermal analyses of steel 1050 slot milling and elemental analyses of the generated surface using different cooling methods have been presented.
