Abstract Increasing demand and resource overuse has prompted the exploration of spent secondary materials as a primary raw material for a variety of applications, leading to a more sustainable environment. Spent electric grid ceramic insulator, one of the waste materials of ceramic industry has a good hardness and strength. It can be reused as value added material in Abrasive Water Jet Machining (AWJM) industry. This present work deals with conversion of electric insulator rejects (EIR) into a cost-effective replacement material for abrasive water jet machining process. Mechanical crushing method is opted to generate the abrasive grit for the machining process. Grit generation pattern and the friability of the electric insulator rejects were determined experimentally. The results indicate that the friability of the processed electric insulator rejects is comparable with the commercially available garnet abrasive. Geometric parameters such as sphericity, elongation ratio, and shape factor for the processed electric insulator rejects were studied using scanning electron microscopy. The machining performance indicators for standard aluminium material such as volume of material removal, kerf angle, surface roughness and cutting width were measured for electric insulator rejects and compared with existing garnet abrasive grain. The experimental results of newly generated electric insulator reject abrasive were matched with performance indicators of the garnet abrasive. The observed deviation was lower proving that it can be used as alternative abrasive in the abrasive jet machining process. Cost analysis and recycling ability predict the economical usability of the newly generated abrasives.

Manufacturing Methods

Today, manufacturing methods are classified into two groups as conventional and non- conventional manufacturing methods. While turning, milling, and drilling are among the conventional manufacturing methods, processes such as laser, plasma, electro erosion, ultrasonic machining and water jet machining are among non-conventional, namely modern manufacturing methods. The cutting tool does not used in modern manufacturing methods. This situation is an advantage. There are some uncertainties on the machining performance of abrasive types, apart from the superior properties of the method. In this study, the effect of different abrasive types on machining performance in abrasive water jet machining (AWJM) was investigated by using computer aided finite element analysis.

Reinforced Composite

Composite materials have taken an imperative place in the material system because of their unique performance in various specialized applications. Fiber inclusion and the heterogeneous property of composites make it more difficult to machine with the conventional machining process. However, several nonconventional methods have been adopted for machining composites, in which abrasive water jet machining (AWJM) was proven to be more effective and a preferable technique in machining of fiber-reinforced composite material. This review article is intended to highlight and categorize the machining performance of the fiber-reinforced composites on machining with AWJM process.

Abrasive Water Jet Machining

The main aim of this investigation is to study the abrasive water jet machining performance of the twill weaved carbon fibre reinforced epoxy composite. Abrasive water jet machining experiment was conducted as per L9 orthogonal array, by varying water pressure, transverse speed and SOD. The performance of the composite was analyzed by measuring the material removal rate and kerf. Using Taguchi analysis, the influences of input parameter over the output response was analyzed. It was found that the MRR is highly influenced by the transverse speed whereas kerf is highly influence by the SOD.
