Page 1-9 - Distance from the top of the bed to the bottom of the slide with the stroke down and adjustment up. In general, the shut height of a press is the maximum die height that can be accommodated for normal operation, taking the bolster thickness and any fillers into consideration.
Page 1-1 - Carburizing — A process that introduces carbon into a solid ferrous alloy by heating the metal in contact with a carbonaceous material — solid, liquid or gas — to a temperature above the transformation range and holding at that temperature. Carburizing is generally followed by quenching to produce a hardened case.
Page 1-1 - ... bending The straining of material, usually flat sheet or strip metal, by moving it around a straight axis which lies in the neutral plane. Metal flow takes place within the plastic range of the metal, so that the bent part retains a permanent set after removal of the applied stress. The cross section of the bend inward from the neutral plane is in compression; the rest of the bend is in tension.
Page 1-4 - In metal forming, a circular plate with a hole in the center contoured to fit a forming punch; used to support the blank during the forming cycle.

Clearance between a mated punch and die; commonly expressed as clearance per side. Also called clearance, punch-to-die clearance. die cushion. A press accessory located beneath or within a bolster or die block to provide an additional motion or pressure for stamping operations; actuated by air, oil, rubber or springs, or by a combination thereof. die forging....
Page 2-23 - In designing stampings with punched holes, it is well to. take into account the fact that only about one-half the thickness of the metal is sheared cleanly to the size of the punch. The rest is torn out by the pressure exerted on the sheared slug. This produces a rough hole tapering in diameter to the size of the punch plus about 10% of the metal thickness (see Figure 6B-1).
Page 2-25 - ... embossment much larger than the hole, then by successive steps forming the desired flange, and finally punching out the hole. This method increases costs and its use should be limited. One way of accomplishing this is to keep the specified flange width at an absolute minimum at all times. A...
