Abstract

Machining operations such as turning, milling, drilling and grinding are commonly used especially in manufacturing industry. These operations have to produce high volume of products in order to ensure companies’ targets are achieved. The problem is how to know when the cutting tool needs to be changed. The main objective of this study are to investigate the correlation between cutting force and tool wear by using the dynamometer, to study the effects and correlation of tool wear on surface roughness and to study the effects and correlation of cutting force on surface roughness. The purpose of this study is to provide clear presentation of the effect of tool wear to the industry. The scope of this study are including the study of tool wear and cutting force in the single point turning operation, and the effect of tool wear on surface roughness using conventional turning machine. During this study, the workpiece that used was mild steel and tungsten carbide was used as cutting tool. This study also focused on establishing the correlation between the cutting force and tool wear by using force dynamometer. Based on the experiment done, the results indicated that, there are some correlation between cutting force and flank wear. Besides, there were some correlation between flank wear and surface roughness and between cutting force and surface roughness.
