Kerf Profile Characteristics in Abrasive Air Jet Micromachining

Article Preview

Abstract:

Abrasive jet micromachining (AJM) is a promising technology for processing brittle materials. Based on an experimental study of hole and groove machining on an amorphous glass by abrasive air jet, the effects of processing parameters on the produced structure profile such as groove width or hole diameter, depth of cut and kerf taper angle are analyzed. It shows that the stand-off distance has a significant effect on the kerf width. Both the hole diameter and kerf width increase notably with an increase in stand-off distance. Positive correlation has been found between the depth of cut and air pressure. Under the same cutting conditions, low taper angle can be achieved when using small nozzles.
