Week 8 - Challenge 3 - Coin Holder Design

AIM:

Create the Coin Holder Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

Take the Thickness of the component to be 2.5 mm

REPORT:

Given class A sufrace:

STEPS:

1. Check the connectivity of the Class A Surface .Ensure that there is no gap between the component, using join command check it or by clicking boundary command.
2. Find the possible tooling direction for the given component,it is the direction of mould(core or cavity) opening and closing.
3. NEXT FIND THE DRAFT ANALYSIS,DRAFT IS required on all the parts in the direction of mould movement in order to allow parts to release (or) eject from the molds properly
4. DRAFT NOMINAL VALUE:3 degree is the nominal value,7 degree for textured faces
5. colour ranges in draft vanalysis

green-draft above 3 degree

red-below 0 degree

blue-0 to 3 degree

Draft is providing angles or tapers on the product engineering features such as ribs,screw bosses,that lie parallel to the direction of release from the mould eases part ejection.

The draft is done based on the tooling direction

creating tooling axis:

creating class b surface:

• Offset the given class A surface to the value of the thickness of the component to get the class B surface.
• All the engineering featrues like screwboss ,ribs ,and other supporting features are found on the class B surface.
• Class B surface is the engineering surface.

CREATION OF CLASS C SURFACE:

FINAL TRIMMED SURFACE:

FINAL CLOSED BODY:

PERFORMING DRAFT ANALYSIS:

CONCLUSION:

Thus the COIN HOLDER is designed ap per design guidelines by using given class A surface

and it also satifies and pass the draft analysis.
