Metal Matrix Composit (MMC) material is one of the advanced materials which have good future prospects.
Their ability to replace conventional materials in many applications is increasing.
Although only few reports on the use of AlN as the reinforcement for Al alloy composites are published, the lack of knowledge concerning the characteristics of these new materials, especially the surface roughness and performance of coated and uncoated carbide tool and wear mechanism in machining often hinders their wider utilization [8].Issues like the material fabrication or machinability and the development of these materials still remain mysterious areas to the manufacturer.

Introduction The abrasive water jet machine is an effective technology for processing various materials.
From the literature survey, it is observed that many works has been reported on waterjet machining process on the materials like aluminum, Grey cast iron, kevlar reinforced phenolic composite, EN 8, and acrylic but researches on AWJM of mild Metal Matrix composites is very few.

The above experimental results show that the size dependence in intrinsic to certain materials, hence accurate understanding and characterization of materials response at small scale is very important in the optimal design of MEMS as well as in evaluating their reliability and performance.
To reduce the difficulties of determining length scale parameters of materials by experiments, gradient elasticity theories of only one additional material constant have been developed.
