Abstract
ABSTRACT: - Surface roughness is an important criteria of the product quality in the machining operations. It is depends on cutting parameters. The objective of this research is to investigate experimentally the influence of cutting parameters on the surface roughness in turning operation, in order to determine the optimal settings of these parameters to improve surface roughness in the turning operations. In this work, surface roughness was measured for steel turned components, which was carried out on a conventional and on a computer numerically controlled (CNC) turning machine with carbide tool at different cutting parameters such as; cutting speed, depth of cut, feed, and the usage of cutting coolant. The experimental results were collected and analyzed. The relation between cutting parameter and surface roughness were determined. The experimental results show that the turned component surface roughness is significantly influenced by the cutting parameters, usage of cutting fluid, and the machine tools. The results obtained from this work show that the surface roughness of the turned components decreased by increasing spindle speed and it increased by increasing depth of cut and feed, while it decreased by using cutting fluid. Also the results show that the surface roughness for the turned components on the CNC machine was less than on the conventional machine using the same cutting parameters.
