| dc.description.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. | en_US |
