A method for manufacturing a sintered magnet includes molding a green compact formed by compacting a magnet powder by press-molding the magnet powder, the green compact forming an R&#x2014;Fe&#x2014;B based sintered magnet having Nd as the principal component and containing a rare earth element R, sintering the green compact by heating to a sintering temperature, so as to mold a sintered magnet, pressure molding the sintered magnet by heating to a temperature not exceeding the sintering temperature, so as to correct dimensions of the sintered magnet, and adjusting the texture of the sintered magnet by aging heat treatment using heated atmosphere produced when correcting the dimensions of the sintered magnet at a temperature not exceeding the temperature during the pressure molding.

A workpiece cutting method basically includes providing a workpiece proximate to a first blade including a first cutting edge. The method further comprises moving a second blade including a second cutting edge in contact with the first blade such that the first and second cutting edges of the first and second blades cooperatively engage to cut the workpiece while maintaining the first and second cutting edges parallel to each other.
