| dc.description.abstract | The objective of this research was to study the influence of cutting clearance on wear behavior of blanking die for high strength steel. Punch material tool steel JIS SKS3, was specified for the hardness of 60 ±2 HRC. Four different clearances between punch and die were 7%, 10%, 13% and 16% of workpiece thickness (t). The high strength steel, JIS G3113 SAPH440 steel strip with thickness of 1.6 mm was experimented. The strip was blanked into circular shapes of 25 mm in diameter. The measurement of flank wear and face wear, weighting and cutting edge quality were studied. The result of the experiments found that the cutting clearance at 7%t had the highest wear, 10%t, 13%t and 16%t had the lowest wear rate respectively. Wear of blanking die which affected on cutting edge quality had the same results, which were die roll, fracture surface and burr were increased while shear surface was decreased. | en_US |
