very tiny pieces of metal from the workpiece at a controlled rate. EDM EDM (electrical discharge machining) is a machining method primarily used for hard metals or those that would be impossible to machine with traditional techniques as milling‚ drilling‚ etc. One important limitation‚ however‚ is that EDM only works with materials that are electrically conductive. EDM can cut small or odd-shaped angles‚ intricate contours or cavities in extremely hard steel and exotic metals such as iconel‚ hastelloy

TESTING YOUR COMPREHENSION 1) Why are fossil fuels our most prevalent source of energy today? Why are they considered nonrenewable sources of energy? Today‚ the three main fossil fuels that are in demand are oil‚ coal and natural gas. These fossil fuels are prevalent because they are efficient to burn‚ ship‚ and store based on high energy content. Fossil fuels also provide for our daily needs such as transportation‚ heating‚ cooking and electricity. Based on our current rates of consumption‚ we

industries. Something must clearly be done about fracking. Today I will express my personal feelings towards this topic and discuss the process and dangers of this industry. So what is it? Hydraulic fracturing or ’fracking ’ is the proccess of drilling and injecting chemically altered fluid into the ground at a high pressure in order to fracture shale rocks to release the natural gas within. Each fracking site or gas well requires an average of four hundred tanker trucks to carry water and supplies

This adverse pollution of groundwater cannot be reversed and it may be difficult to detect and address all the problem sources because Fracking Companies do not need to
