In most of the metal machining process cutting fluid are more problematic in terms of both employee and environmental pollution, generally cutting fluid causes economy of tool and it become easier to keep tight tolerance and maintain the workpiece surface properties without damages. Due to this some alternatives has been sought out to minimize or even to avoid the use of cutting fluid in machining process. Some of the alternatives are dry machining and machining with minimum quantity

... (MQL).The aim of the present project is to investigate the machining parameter on surface roughness (R a), chip removal and tool wear rate onworkpiece H13 steel in turning process. The approach was based on minimum quantity lubrication (MQL) technique. MQL uses a spray of small oil droplets in a compressed air jet. The lubrication is sprayed directly into the cutting zone, since the air jet carries the oil droplets directly in the cutting area to provide efficient lubrication.
