ABSTRACT
In metal cl.Itting operations, performance of the cutting tool is the major determinant
of the productivity, functionality and production cost of the machined component. In this
work, the performance of uncoated cemented carbide tools with International Standard
Organisation (ISO) designation SNMA 120406 was evaluated for tumitu; of NST 37.2 steel.
Turning operations were conducted on M300 /-Iarrison type lathe driven by 3.0 hp Kapak
induction motor. The cutting conditions used were: cutting speed, 20.42, 29.06 and 42.42
m/min; feed rate, 1.0, 1.8 and 2.2 mmlrev; and depth of cut, 0.2, 0.4 and 0.6 mm under dry
machining. Results showed that both flank and nose wear increased with increase in
number of pass, cutting speed, depth of cut and feed rate. The optical surface roughness of
the machined workpiece varied from 0.658 - 0.924 and case hardening of the machined
surface was observed. Segmented chips with smaller coil radii, which were less voluminous
and more manageable were produced at all cutting conditions investigated. Chip breakabi/ity
tends to increase with increase in cutting speed. The use of uncoated carbide tools has
proved to enhance the productivity and surface quality in turning of NST 37-2 steel
