Abstract
The main purpose of cutting fluid in a machining is to cool the work piece, reduce friction, and wash away the chips. Introducing cutting fluid in a metal-cutting process can reduce the rate of tool wear and improve surface quality also. The large usage of cutting fluid causes hike in machining cost as well as environmental threats. In the past, there have been some attempts to minimize the amount of cutting fluid in turning. To accomplish that purpose, a minimal-cutting-fluid system was developed. In the present investigation a specially formulated cutting fluid with rich water as 80% applied as a high velocity, thin pulsed jet at the immediate cutting zones at an extremely low rate of 8 ml/min by using a minimal fluid application system during turning of Oil hardened non shrinkable steel. In this investigation the work piece selected was OHNS steel. The performance of hard turning of OHNS steel with minimal cutting fluid is studied and then compared with conventional wet and dry turning. The minimal fluid application system can reduce environmental pollution, improves machining performances, and consequently reduces total production cost because of minimum consumption of cutting fluid.
