An Investigation into the Multi-Pass Radial-Mode Micro Abrasive Air Jet Turning of Fused-Silica Rods

With the increased requirement of miniaturization structures on hard and brittle substrates, micro abrasive air jet turning technology has become a promising machining for manufacturing structures. This paper presents an investigation multi-pass radial-mode fused silica. The effect parameters depth cut materials removal rate was analyzed. waviness striation formation mechanisms were studied. It found that increasing number passes significantly increases rate. When surface speed is reduced, increases. may be attributed to intersection overlap adjoint footprint. crossed striations have been found, which lead elimination striation. A predictive model material developed using dimensional analysis method. assessed shown able give adequate predictions.
