A Study on Characteristics of Precision Shearing for Tailor Welded Blanks

An objective of this study is that when the steel sheet for automobiles would be sheared by using shearing machine, it is to design the forms of pad for obtaining the precision shearing surface to satisfy the conditions required to laser beam butt welding for processed sheared surface and to establish the appropriate condition against the size of gap between strength of pressure and location and clearance between punch and die. For doing so, we will attempt to make a precision of the most possibility of shearing machine by the shearing machine in analyzing the characteristics of the shearing working upon analyzing and clarifying the interrelation among these.
