control punch, stripper and part deflection. When punching angle exceeds 15 deg., it generally is less costly and more reli- able to add an additional operation or use a cam.
Stampers also may struggle with hole-size accuracy when performing angular punching. The punch cuts a hole open- ing in the part that on a slight angle, but the part print requires the hole size to be measured perpendicular to the part surface. As a result, the shape and size of the punch will be different than the final hole diameter (Fig. 3).
Progressive-Die Strip Carriers
When cutting stretch carriers in progressive-die strips, be sure to cut the inside carrier first—cut only half-way through the material and use a pressure pad that bottoms out in the die cavity. The bottoming pad ensures the cut will only pen- etrate halfway through the material thickness. This eliminates having to push the blank back into the punched opening, which usually leads to slivers in the die. Cut the outer carri- er next, using the same technique.
Punch pilot holes in progressive strips undersized if the final diameter is critical. The hole may be punched larger or shaved in the final operation to establish its final size.
Applying these cutting and punching guidelines should help improve product quality and process reliability for many stamping operations. MF
