Abrasive jet micromachining pdf. Abrasive jet machining ajm utilizes a high velocity jet of abrasives to remove material from work surface by impact erosion. It is a promising machining technique for the cost. In the abrasive jet micromachining ajm process a jet of small particles is directed through an erosion resistant mask opening so that micro sized features ie micro channels holes etc can be machined for the fabrication of microfluidic mems and opto electronic components.

Abrasive jet machining definition. The abrasive jet micromachining ajm of elastomers and polymers such as polydimethylsiloxane pdms acrylonitrile butadiene styrene abs and polytetrafluoroethylene ptfe for use in micro. The jet of abrasive particles is carried by carrier gas or air. The high velocity stream of abrasive is generated by converting the pressure energy of the carrier gas or air to its kinetic energy and hence high velocity jet. In abrasive jet machining a focused stream of abrasive particles carried by high pressure air or gas is made to impinge on the work surface through a nozzle and the work material is made to impinge on the work surface through a nozzle and work material is removed by erosion by high velocity abrasive particles. In abrasive jet machining ajm abrasive particles are made to impinge on the work material at a high velocity.
