ABSTRACT

17-4 PH stainless steel is one of the most imperative type precipitation hardened alloy steel. It has excellent property of corrosion resistance and superb mechanical strength, due to this it is used in marine vessels. These properties make that it to be used in salt water applications, including it has many applications like in nuclear industries, paper industries, food processing equipment, turbine blade design and in oil and gas industry. In the current study, the process parameter is feed rate, spindle speed, and type of solid carbide drill bits. The comparison between the performance of uncoated and TiAlN coated solid carbide drill bits are discussed herein. Also studied surface roughness and Chip morphology has been examined thoroughly. The result indicated that side flow of chip of material increases with cutting speed that could be reduced by drilling with a coated drill bit. Also, chip thickness is also decreased with feed.
