Surface Morphology Transformations After Sequential Laser Treatment During Turning of Mild Steel
N. Deswal, R. Kant, S. Yadav and P. Kumar
Surface morphology of a final product has been the primary focus of any product to achieve better part performance and durable life. Surface morphology is affected by several factors such as friction, heat generation, interaction between the cutting tool and the workpiece surface, etc. The present article aims to investigate the surface morphology of mild steel during the sequential turning and laser post treatment processing. Cutting speed, laser power, and laser spot diameter have been varied to analyze the surface roughness and machined surface damage during the conventional turning (CT) process and sequential post-processing via laser. The surface roughness and machined surface damage are found to be higher for the sequential post-processing via laser than the CT process for most of the conditions. However, for certain cases, the surface roughness and machined surface damage are observed to be lower for sequential post-processing via laser than the CT process.
