Laser glass cutting techniques-A review

With the advancement of glass technology in recent times, glass has become one of the most important engineering materials in architectural, medical, automotive, flat panel display, and electronics applications. Desired shape and size of the glass can only be achieved through accurate and precise cutting technique. Laser technology has an advantage over traditional cutting processes for glass due to good quality, surface finish, and high speed of operation. This paper provides a review of all the laser glass cutting techniques discovered in recent work and forms a comparison framework, in particular, their limitations and their current status which would facilitate prospective research and future development.
