A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake - or may occur slowly, in the form of creep. Faults may range in length from a few millimeters to thousands of kilometers. Most faults produce repeated displacements over geologic
Error-proofing is a method of 100 percent inspection at the source, rather than down the line. In essence, error-proofing improves the predictability of the resultant part of the manufacturing process. Therefore, the actual inspection time, which is non-value added time in the process, is reduced. Each process hand-off must be a perfect product ...

Jul 03, 2021 Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away by wheel action.
