Investigation into Machining Characteristics of Tri- Alumane Zirconium Particle Reinforcement in Metal Matrix Composite Using Ultrasonic Machining Process

Particle reinforced metal matrix composites (PRMMCs) are the materials that are extremely difficult to machine using conventional manufacturing method due to high tool wear caused by presence of the hard ceramic reinforcement. This paper presents details of an investigation into the machinability of TriAlumane zirconium (Al3Zr), Zirconia (ZrO2) and Silicon carbide (SiC)particulate reinforcedalu...

Metal Removal Rate Optimization in Electric Discharge Machining Process

Electrical discharging machining (EDM) has become an outstanding approach in the field of metal cutting especially for conductive metals. It’s very difficult to cut the conducting metals with the aid of traditional machining. The main object of the present work has to investigate the effects of various EDM input parameters like pulse on time (Ton) pulse off time (TOFF) as well as the influence ...

Prediction of cutting forces in machining of metal matrix composites

This paper presents a mechanics model for predicting the forces of cutting aluminum-based SiC/Al2O3 particle reinforced MMCs. The force generation mechanism was considered to be due to three factors: (a) the chip formation force, (b) the ploughing force, and (c) the particle fracture force. The chip formation force was obtained by using Merchant’s analysis but those due to matrix ploughing defo...

Electrical Discharge Machining of Aluminum Metal Matrix Composites- A Review

Electrical discharge machining (EDM) is the process of machining electrically conductive materials by using precisely controlled sparks that occur between an electrode and a work piece in the presence of a dielectric fluid. Aluminium metal matrix composites (AMMCs) refer to the class of light weight high performance aluminum ceramic material systems. The reinforcement in AMMCs could be in the f...
