Quiz 5 Solution True or False: 1) The energy conversion in EDM is electric energy to thermal energy. T 2) The energy conversion in ECM is electric energy to chemical energy. T 3) The energy conversion in laser beam machining is light energy to thermal energy. T 4) The machining mechanism of Abrasive water jet machining is erosion. T 5) Ultrasonic machining could be used to cut hard, brittle work materials such as ceramics, glass and carbides. T 6) Water jet cutting could be used to cut metal and ceramic materials. F 7) Electron-beam machining has higher resolution than laser beam machining due to the fact that wavelength of electron beam is much shorter than laser beam. T 8) EDM process could be used to machine electrical insulated materials. F
