The objective of this study is to determine numerically, the effect of different
parameters on springback phenomenon during sheet metal forming process.
Nonlinear numerical simulation was performed using a finite element commercial
MSC MARC software. Numerical results were verified with available experimental
data obtained from the literature.
Four parameters namely, the effect of material type, sheet thickness, friction and
punch radius were evaluated in springbak phenomena.
In evaluating the effect of material types on springback phenomenon, high tensile
steel (HTS), mild steel (MS), deep drawing steel @DS) and commercially pure
aluminium (CA) were used. The computational results showed that the value of
springback is influenced by type of material.Deep drawing steel displayed the highest value of springback (3.48"), while the
lowest springback value was recorded for mild steel (2.06").
The effect of friction coefficient on springback phenomenon was determined using
different friction coefficient ranging between 0.1 and 0.5 with increment of 0.1.
Friction coefficient 0.5 displayed the highest value of springback (3.8") and the
lowest value of springbak (2.4") was recorded for friction coefficient 0.1 which
means that springback increases as friction coefficient increases.
Sheets have thickness of (3mq 5mm, 8.3rnrn, lOmm and 12.8mm were evaluated
for springback phenomenon. The results showed that the springback values decreases
as sheet thickness increases. 3 mm sheet computed to have the highest value of
springback (7.65"), 12.8 mm sheet had the lowest springback value (2.88").
Finally, (3mm, 5mm, 8mm, lOmm and 12mm) punch radius were also evaluate to
study their effect on developed springback,. The results showed that as the punch
radius increases the springback vaIues increases. The punch with 12mm radius
exhibited the highest value of springback (5.84") and the lowest springback value of
lo was computed for punch with radius of 3mm. |
