This study delves into the surface finish characteristics of OHNS (Oil Hardening Non-Shrinking) die steel during turning using CCMT, DNMX inserts the research aims to analyze surface roughness, waviness, and form error under varied cutting conditions. The effect of dominant cutting parameters on surface roughness were analyzed i.e variation in cutting speed, feed with surface finish for various inserts and EN 31 and E0300 oil harden non shrinking die steel for dry and wet condition were analyzed. Experimental trials with different cutting speeds, feed rates, and depths of cut are conducted, and surface finish is monitored using precision instruments. Keywords: OHNS Die Steel, Surface Finish.

INTRODUCTION Surface finish is a critical factor influencing the quality and functionality of machined components across diverse industries, particularly in manufacturing. This significance is especially pronounced in applications where precision and durability are paramount, such as in the production of components from OHNS (Oil Hardening Non-Shrinking) die steel. OHNS die steel, prized for its exceptional machinability, wear resistance, and dimensional stability, finds extensive use in tool and die making.
