Experimental Study on Incremental Forming of Ta Sheet
The tantalum sheet is ideal biological compatible material.It has widespread application prospect in surgical department.It is very meaningful to make tantalum recovery-part by incremental forming technology.The incremental forming experimental model of rolling 1mm tantalum sheet was established,the formability of Ta sheet incremental forming under different tool shapes,feeding size and surface lubrication was studied.The incremental forming limit angle of 1mm Ta sheet is about 56° by calculation.
