In the deep drawing of cups, blanks show a tendency to wrinkle up around the periphery (flange). The most likely cause and remedy of the phenomenon are respectively,
A
Buckling due to circumferential compression: increase blank holder pressure
B
High blank holder pressure and high friction: reduce blank holder pressure and apply lubricant
C
High temperature causing increase in circumferential length; apply coolant to blank
D
Buckling due to circumferential compression; decrease blank holder pressure.
