This document summarizes the results of Phase 2 of a project investigating the mechanical properties of a CIN4-T matrix composite material for milling machining applications. Experimental techniques were used to measure surface roughness, drilled hole accuracy, and taper angle after machining samples using electrodes made of different materials like nickel, bronze, steel, and titanium. The aim was to evaluate the mechanical properties of the composite, including hardness, fracture toughness, and wear resistance for precision machining applications. Work for Phase 2 included searching for an EDM shop, analyzing the best, worst, and optimum drilled holes, conducting confirmation tests, and drawing conclusions.

5. AIM :
The purpose of this study is to investigate the microstructure and mechanical properties of a Si3N4-TiN matrix composite for
precision machining applications.
OBJECTIVE :
Evaluate the mechanical properties, including hardness, fracture toughness, and wear resistance, of the composite.}
Investigate the effects of TiN content on the microstructure and mechanical properties. } Analyze the suitability of the
composite for precision machining applications.
ABSTRACT :
Si3N4-TiN composites have extensive manufacturing applications because of their first-rate mechanical and thermal
properties. Conversely, they are very demanding on machines that use conventional practices because of their superior strength
and hardness. Electrical discharge machining is a viable substitute for machining of Si3N4-TiN composites through electrical
erosion. The materials processing characteristics of a Si3N4-TiN composite using EDM and EDM performed with 3D printed
electrode.
