Effects of PCD and uncoated tungsten carbide inserts in turning of in-situ Al6O61-T1C metal matrix composite

摘要

In the present investigation A16061-TiC with 2 wt% TiC, 4 wt% TiC is produced by in-situ technique, SEM and EDX are performed on the fabricated composite for to know the presence of TiC reinforcement/ The fabricated composite rod is subjected to turning experiments in dry environment for to find out the cutting force and surface roughness. The experiments are performed at five different ranges of cutting speed, feed rate and depth of cut by using PCD and uncoated tungsten carbide insert. From the experimental results it was find out that cutting force and surface roughness were decreasing with increase in cutting speed and increasing with the increase in feed rate and depth of cut. The experimental results also shows that the values of cutting force and surface roughness are increased by using uncoated tungsten carbide insert than that of PCD insert.
