Abstract

This research is focused on the surface integrity of medium carbon machined by TiC/WC (Titanium Carbide coated) tool insert. The machining involved turning at high speeds using the computer numerical control (CNC) machine and without the presence of cutting fluid. The cutting speed was varied from 300m/min to 600m/min.The analysis of the surface integrity was conducted using Scanning Electron Microscope (SEM) and Axioskop (metallurgy) microscope. The surface roughness values of the samples were determined using Mitutoyo's surface tester. Highest value of surface roughness as determined by the Mitutoyo's surface tester was 3.llJ.1m. With cutting speed 600m/min and machining time 12.5 minutes the highest surface roughness has produced. Therefore the lowest surface roughness was taken from 500m/min cutting speed and 7.5 minutes of machining. The value was 0.84J.1m. The result from the experiment showed that the surface roughness values increase with increasing tool wear. The TiC/WC inserts as used in this experiment were found able to produce good surface finish when used in high speed turning of AISI 1045. It produce good surface until it reach the machine parameter of 600m/min cutting speed and 12.5 minutes machining time.
