True and False (correct the false) 1. In USM, tool tips must have high resistance and fatigue strength. 2. The machinability of USM depends on brittleness criterion. 3. In EDM, negative ions (electrons) collide with positive ions to generate heat. 4. "In EDM, high pressures allow the metal to evaporate." 5. In AJM, corrosion is the mechanism of removal of material from the work piece.

Nondestructive evaluation: Nondestructive evaluation (NDE) describes methodsthat quantitatively characterize materials, tissues, and structures by noninvasivemeans such as X-ray computed tomography, ultrasonics, and acoustic emission.Recently, NDE was used to detect defects in steel castings. (JOM, May 2005.)Assume that the probability that NDE detects a “hit” (i.e., predicts a defect in a steelcasting) when, in fact, a defect exists is .97. (This is often called the probability ofdetection.) Also assume that the probability that NDE detects a “hit” when, in fact,no defect exists is .005. (This is called the probability of a false call.) Past experiencehas shown that a defect occurs once in every 100 steel castings. If NDE detects a“hit” for a particular steel casting, what is the probability that an actual defectexists? Step by Step Full procedure required.
