Abrasive jet micromachining of acrylic and polycarbonate polymers at oblique angles of attack

Abstract Masked and unmasked micro-channels were machined in polymethylmethacrylate (PMMA) using an abrasive jet of 25 m Al2O3 particles at a variety of impact angles. The erosion rate was found to depend on the jet scanning direction when the nozzle was inclined with respect to the target surfa
