PENGARUH KETEBALAN MATERIAL DAN CLEARANCE PROGRESSIVE DIES TERHADAP KUALITAS PRODUK RING M7
Abstract: Washer component
manufacturing is mostly
done by blanking
and piercing technique. The
purpose of this research is determining the effect of clearance on product
quality and to
determine the optimal
clearance. Good quality
of washer could be
achieved by cutting
process on the
punch and die of
progressive dies where the provisions of clearance properly calculated. The
research was conducted by using the M7 washer, M7 washer making use of progressive
dies. The research
was conducted with
a wide range
of plate thickness, between
0.7 mm to 1.4 mm
and also varies
clearances between 0.025 mm /
side up to 0.125 mm / side.
The result shows
that material thickness
affect to quality
of ring M7 product.The thicker of material will cause
the higher burr, in that means poor quality.The
clearence affect to
quality of ring
M7 product.The wider clearence will
cause the higher
burr, in that
means poor quality.Refer
to research conducted, the
best quality of
product set on
0,7 mm material thickness with
0,025 mm clearence
which is 0,003
mm burr developed.
