Abstract

This project presents the experimental investigation that was done on the machining performance of carbide coated cutting tools on difference cutting speed and condition. The workpiece materials selected in this project was Aluminium Alloy 2024. The coated cutting tools that used was Canela insert grade PM25. The cutting tools was undergo machining tests by lathe machine and then it will be analysed in order to study their performance. The selected coated cutting tools were tested at various cutting condition which involved two setting conditions (dry and wet). Only one parameter was varied which was cutting speed. The feed and depth of cut were kept constant for all the setting conditions. At the above cutting condition, the performance characteristics measured were the tool wear. A scanning electron microscope (SEM) and stereo microscope (SM) were be used to examine the tool wear and surface roughness. From the analysis, result showed that tool wear are occurred for both cutting conditions. However, wet cutting performed better as compared to dry cutting. As per cutting speed, it shows that increased
