The invention provides polishing pads comprising a deformable polishing pad body and magnetically sensitive particles dispersed therein, wherein one or more properties of the polishing pad are altered when in the presence of an applied magnetic field. The major and minor jaws are aligned in the receptor cavity of a configured rectangular tube and are actuated to fully and to frictionally engage the receptor cavity. The object based storage system includes the server. The position, shape, and size of each guiding flank located downstream in relation to the direction opposite the broaching direction are associated with the position, shape, and size of the associated cutting flank in the preceding row. This method can form a gate hole at a high precision in size.
