| Summary: | This thesis studies related to simulation modeling and experimental verification of
the cylindrical cup drawing in three cases by using a dry film lubricant, lubricating oil
type and without lubrication. Expected results included the withdrawal in the
determination of the optimum speed of the punch and the distribution of the metal
thickness (blank) will reduce cost and the manufacturing process. Prior to finite element
analysis it requires understanding of properties and modeling of sheet metal. In the finite
element analysis, the effect of the lubrication and punch velocity on the cylindrical cup
wall distribution will be evaluated. Through experimental study, the optimum and the
maximum value of speed are 2mmls and l0mmIs respectively. This value is determined
without blank above the tear failure. Comparison between simulation and experimental
studies indicate finite element model can be used where it is observed from the result of the thickness between the simulations and experimental that show similarities. |
