The removal process using the waterjet entails the chipping action, which is especially effective on materials that are hard and brittle like glass, silicon, tungsten and ceramics (Momber & Kovacevic, 2012). The materials that are soft and resilient like rubber and some plastics tend to resist the chipping action and therefore, cannot be processed effectively by AWJM (Selvam et al, 2017). It has also been discovered that no workpiece chatter occurs with this process due to the large quantity and the small mass of abrasive result in uniform loading of the part (Wang, 2003). Therefore, AWJM can produce objects that are fine, in extremely brittle objects. The research has also discovered that AJM is one of the nontraditional processes that are least expensive because it can be purchased for below 5000 dollars (Saxena et al., 2018). The AWJM usually consists of four major subsystems namely the gas propulsion system, the
3 metering system, the delivery system and the abrasive collection system (Momber & Kovacevic, 2012). The gas propulsion system plays an important role in ensuring there is a steady supply of clean and dry gas that is useful in propelling the abrasive particles (Selvam et al, 2017).
