Which parameters have significant influences on the amount of springback in metal bending? Select one O a Material plastic strain, yield strength and bend radius to sheet thickness ratio Ob Material shearing strain, yield strength and bend radius to sheet thickness ratio Oc Material Young's modulus, stress and bend radius to sheet thickness ratio Od Material Young's modulus, yield strength and bend radius to sheet thickness ratio If there is a shape distortion occurring in a bent part due to "springback, which of the following measures could be used to correct that shape? Select one: O a. Using more workers to watch what happens during the metal bending process O b. Reducing the production steps in metal bending Oc Using larger bending machines for production Od Using overbending and/or re-bending in production What are the common defects that often occur in the parts formed by deep drawing of sheet metal? Select one: O a Excessive increase in the sheet metal thickness and partially having scratches on the metal surface ob Too little change in the sheet metal thickness and too many wrinkles formed OcFracturing at the corner sections of the component, wrinkles in the flange, and scratches on the surface of the component O d. Sheet metal does not move and has wrinkles in the flange and scratches on the surfaces
