DIE- ENTIRE PRESS TOOL EMPLOYED TO STAMP AND FORM PARTS
FROM SHEET METAL, ASSEMBLE PARTS TOGETHER, AND PERFORMA VARIETY OF OTHER OPERATIONS. IT ALSO REFERS TO THE LOWERHALF OF THE PRESS TOOL, i.e., THE UNIT WHICH IS CLAMPED TO THEBOLSTER PLATE OF THE PRESS. THE WORD PUNCH REFERS TO THE
ENTIRE UPPER HALF OF THE PRESS TOOL, MORE SPECIFICALLY, ITREFERS TO ANY SO-CALLED MALE SECTION WHICH PUNCHES ORFORMS METAL WITHIN A FEMALE SECTION,THE FEMALE BEINGKNOWN AS A DIE SECTION. THIS ARRAY OF DEFINITIONS STANDS UPQUITE WELL IN MOST DIE WORK, ALTHOUGH IT TENDS TO BECOMECONFUSING IN SOME AREAS OF THE TRADE. FOR EXAMPLE, IN ACOMPOUND DIE THE PUNCH SECTION IS MOUNTED IN THE DIE ANDTHE DIE SECTION IS MOUNTED IN THE PUNCH.
