An Optimization Study of Fluid Jet Flow in a Convergent Divergent Nozzle Geometry Used for the Cooling Systems of Machine Tools

Abstract:

In this work it was performed a fluid mechanical study of cooling systems for metal cutting. In these machine tools are developed temperatures processing this should be minimized so as not to damage of the tool durability. Therefore should correlate pressures, temperatures and fluid flows used. Also the physical characteristics of fluids used are important for better cooling of the tool in the work area. All these factors lead to a better surface of machined area.
