Recent Studies In The Application Of Internal Cooling System In Conventional Machining Process

摘要

In general, most of the manufacturing industries use lathe machine, because of its applications in various fields of automotive, defense, missile technology and aerospace. The workpiece material used in these fields are owing high hardness and good physical properties. In this machining process extreme heat is generated, which interrupts the chip flow. In turn it effects the surface finish of the machined surfaces and also decreases the tool life. Tool temperature cause damages like wear resistance and reduction of mechanical resistance therefore efficient cooling strategies are used to minimize the cutting zone temperatures. Now-a-days demands increasing on machining new cooling techniques, among them closed internal cooling system can be an alternative to green environment. Application of Nano particle blended in cutting fluids reduces the cutting zone temperatures, increases tool life, material removal rate and surface finish. However, the existing literature shows that under same application thermophysical properties are improved from other fluids. In this paper, a concise study of operating and machining conditions of lathe machine under internal cooling system is made and observations from the literature survey are discussed.
