Abstract

Abstract

A set of processing device is designed to collect the melt particles during laser cutting zirconia ceramic. The melt particles morphology including quantity, shape, mean dimeter, standard deviation, and distribution are studied using the image processing software of Imagine-Pro Pluse(IPP). Various cutting experiments with different ceramic thicknesses(0.8mm, 1.0mm, 1.5mm and 3mm) are taken based on controlling of vapor-to-melt ratio. Results of IPP observation show that, with the ceramic thickness increased, the percentage of spherical molten particles is declined from 99.21% to 89.81%, while the cakey and dumbbell shaped molten particles are ascended from 0.79% to 7.44% and 0 to 2.75% respectively, and the mean and standard deviation of spherical melt particles diameter also are enlarged. Simultaneously, with the increasing of mean and standard deviation of spherical particle diameter, the roughness of kerf surface is deteriorated from 2.287μm to 5.946μm. The establishment of geometric model reveals the connection between the form of removal molten particles and cutting quality. The larger the percentage of spherical molten particles, the smaller the mean diameter and standard deviation, and then the better the cutting quality. The high quality cutting sheet is achieved finally.
