Machining of borosilicate glass using Normal-Pressurized-Bed and Fluidized-bed AJM set ups

Hard and brittle materials like glass, quartz and composites can be effectively and economically machined, drilled, deburred, and surface etched with the most prominent abrasive jet machining (AJM) process to achieve good surface quality and higher material removal. This experimental work provides a...

Description
Summary:Hard and brittle materials like glass, quartz and composites can be effectively and economically machined, drilled, deburred, and surface etched with the most prominent abrasive jet machining (AJM) process to achieve good surface quality and higher material removal. This experimental work provides a comparative study of drilling of rectangular glass pieces with normal pressurized bed (NPB) and fluidized bed (FB) AJM setups. The normal pressurized bed is first fabricated and installed to conduct the fifteen number of experiments according to the chosen response surface methodology (RSM) of design of experiments (DOE). Then the fluidized bed mixing chamber AJM setup is designed and fabricated to perform the same number of experiments with the same input parameters for making a comparative study. The surface crack mechanism in both the cases is investigated from the SEM micrographs.
