high utility draw functions are more likely to be implemented. Installing sensors or timers is typically easily and quickly accomplished and can be expanded to additional areas as savings are proven and employees adjust to the change. In addition, there may be tax and/or utility company incentives for energy efficiency projects like these. This study presents an experimental investigation and finite element simulation of Electro Discharge Drilling (ED-Drilling) of Polycrystalline Diamond (PCD). PCD has many outstanding properties including uniformly high hardness, high wear resistance and strong corrosion which are the main causes of widely using . The world's largest digital library.
