The study Quality cutting edge produced of tool steel of reuse

Abstract

The main objective of this research is to study the quality of the cutting edge. Obtained by cutting with a JIS SKD 11 tool steel, through the use of recycled and reused. Study later reuse. After going through the process of heat treatment will affect the quality of the cutting edge of the work piece. In this research use punch diameter 20 mm and diameter 15 mm. Clearance between punch and die is 5%, which reduces the size of punch and die used size 25 mm cut materials were stainless steel grade 304, thickness of 2 mm . Experimental results showed that the quality of the cutting edge is likely to decline when compared to the Punch and die having never been used before.
