Experimental study on surface generation in optical glass with fluid jet polishing process

Fluid jet polishing process is an inexpensive technique and capable to produce ultra-smooth surface. In fluid jet polishing process, the surface generation mainly depends upon the size and type of the abrasive particle, the jet pressure, the exposure time, the impact angle, etc. In this work, experimental investigation were carried out to study the influence of different slurry exposure time on surface roughness of optical glass with varying jet pressure, particle diameter and type of particle at 30° impact angle. The surface roughness measurement and surface morphology characterisation were done to understand the surface changes.
