This paper presents a survey on the effect of chilled air application throughout dry machining of MS, AISI202 using single point cutting of HSS. Through the Taguchi design of experiment, 32 experiments are conducted under various cutting parameters such as spindle speed, two standards of depth of cut along with feed rate under traditional dry machining as well as machining under supply of chilled air (at temperature of 15o C to 12o C) on lathe machine with HSS cutting tool. The setup was fabricated and used for the supply of chilled air at the set temperature. The surface finish and tool life were measured as the output of material's Machinability justification with the use of equipment such as surface profiler and profile projector. The results showed that the supply of chilled air has improved, tool life and surface finish by 19.23% and 23.59% respectively compared to dry air machining. Due to the supply of chilled air, machining temperature, and tool wear has been reduced. Hence surface finish can be improved significantly. It was found that, Conducted experiments has been enhanced the tool life by reducing the tool wear as well as improvement of surface finish
