Week 9 - Attachment Feature Creation - Challenge 1

Draft analysis of Coin Holder

• Draft analysis on a component is done to ensure there is certain draft amount of draft is maintained so that the component is easily ejected from the mold, (ideally 0.5 degree is maintained and upto 3 degree we mostly tend to go with plastic for sheet metal we tend to go above 7 degrees).

• HOW TO PERFORM DRAFT ANALYSIS :

  • To perform draft analysis ensure the materials option is selected in the view mode and select the feature draft analysis option.
    • Create the tooling axis using bisecting method.In bisecting method we create a bisecting a line with intersects of the walls in X direction and Y direction.
    • Then the bisecting line between both intersects is considered as the tooling axis.
    • Generally tooling axis is the path in which the cavity interacts with the core , bisecting method is one of the method to configure the invisible tooling axis.Next in select the compass option and drag it on to the tooling axis and press anywhere on the component.

• COLOR CODING:

  • In the color code tab you see 3 colors , green , red and blue.
  • You can customize the value of draft angle respective of its color.
  • Then understand that the surface which show as green has a draft on it respective of angle which we want.
  • Now select the now select analysis under running point option in the display row and swipe along the surface which gives the approximate draft angle that is present as shown below.

  CONCLUSION:

  After considering all the draft analysis results,the design of the current plastic component is valid
