Abstract
The erosion process in micro-machining of brittle glasses using a low pressure slurry jet
is discussed. The process capability of the technique is assessed by examining the machined surface
integrity in relation to fluid flow dynamics in micro-hole generations. The holes produced are
characterised by a “W” shape in the cross section, while the surface morphology is distinguished by
three zones associated with the fluid flow behaviour, i.e. a direct impact zone, a wavy zone and an
accumulation zone. The surfaces appear to be smooth and without cracks, indicating a
predominance of the ductile mode erosion process. With the increase of pressure, the erosion rates
can be enhanced as a result of the expending of the accumulation zone while the outer diameter of
the holes remains unchanged. This study shows that this technique can be used for micro-machining
with high surface quality, and provides an essential understanding for further research in the
avenue.
