This paper conducts a study on a pre-mixed micro abrasive water jet machining system. A new kind of abrasive mixing tank and the jet system are designed and tapped for the pre-mixed micro abrasive water jet machining system. The performances of the pre-mixed micro AWJ machining system are tested, and some polishing experiments are conducted for hard-brittle materials such as silicon nitride. The results show the feasibility and the advantage of the pre-mixed micro abrasive water jet machining system for polishing hard-brittle materials.

This paper conducts a study on a precision micro abrasive waterjet (PMAWJ) machining system. A new kind of precision micro abrasive water jet system is designed and tapped. The flux and the flow velocity of the PMAWJ system are tested by experiments. Using the micromachining system, a group of polishing experiments is conducted for two kinds of hard-brittle materials such as silicate glass and silicon nitride. The results show the feasibility and the advantage of the PMAWJ machining system for polishing hard-brittle materials.

Complex Process

Engineering ceramics feature resistance to high temperature, corrosion, wear and hot impact. However, it is difficult to machine this material in conventional machining methods because of its high hardness and brittleness as well as inconductivity, thus restricting its application area. In recent years, more and more importance has been attached to the new machining method of engineering ceramics, i.e. abrasive water-jet. Feature high efficiency and low cost, the method can be used to process the products of complex shape. However, abrasive water-jet machining of advanced ceramics is a very complex process. The effect of machining on brittle materials, and advanced ceramic materials in particular, have not yet been very well understood. The present research investigates the effect of abrasive water-jet machining on ceramics. The study will increase the general understanding of the machining phenomena for more successful application of abrasive water-jet machining on brittle materials.

Abrasive water jet (AWJ) technology, due to its potential advantages, is a promising machining method for precision machining brittle materials. In this research, the AlN ceramics was polished using an AWJ machining system. A considerable processing quality has been achieved and a reduction up to 62% of the surface roughness has been obtained. Effects of different process parameters on the surface roughness of the polished workpiece were analyzed. Under the current conditions of the experiments, using a lower impact angle, smaller abrasives and a lower nozzle traverse speed may be appropriate for polishing AlN ceramics.
