PdP136. Application of piezoelectric actuator to burr-free blanking

Abstract A high power, multilayer piezoelectric ceramic actuator has been developed and has been applied to burr-free blanking of thin foil using the reciprocating blanking method. A ternary system, Pb(Ni1/3Nb2/3O3-PbZrO3-PbTiO3, was selected for piezoelectric ceramics prepared using the conventional method. The following results were obtained from this study. (1) The maximum force and displacement of the actuator (D=35mm) induced by an applied voltage of 400V were 2. 8×104N and 50μm respectively. (2) It was possible to blank foil 13 – 80μm thick using piezoelectric ceramic actuators with this method, and obtain burr-free edges.
