Abstract

In laser polishing, a laser beam is used to melt the surface of a work piece to improve surface quality. An optimum combination of process controlling parameters and state of laser beam output is the key strength of laser polishing. Laser beam output power, feed rate, path interval, and spot size are critical parameters in the laser polishing process effect on the thermal state of surface quality. In this study, experimental tests demonstrate that it is an optimum value of the proper processes condition in the pulse laser and CW laser system. The proposed dominant controlling parameters, method for examining morphology; several experimental conditions; and details from performance improvement of surface roughness are presented.
