Week 8 - Challenge 3 - Coin Holder Design

TO DESIGN A COIN HOLDER BY USING CLASS A SURFACE

AIM: To design a coin holder Plastic component through the given Class-A surface by creating a tooling axis and draft analysis of the given surface.

DESIGN PROCEDURE:

• To setup the class-A surface and to creating a tooling axis

• add draft angle
• To create a base surface of model
• To create a B-surface
• To create a C-surface
• To use close surface for creating a solid part model

CLASS A SURFCE

TOOLING AXIS

It is direct method

• For this model, to use a line at mid-point of the base of the coin holder
• Due to perpendicular walls of the class A surface

DRAFT ANALASIS

1 The Drafting analysis was performed on the class-A surface by using the Feature Draft Analysis command.

2 Using this command, the compass was set on the main tooling axis and the Draft angle was changed to 3 degree

B SURFACE CRAETION

• To create a side wall by extract the class A side faces
• To untrim the extracted side walls
• To extrapolate them for make sure to pass through all together for merge
• To trim the unwanted faces from walls by trim
• To offset the walls up to 2.5 mm

C SURFACE CREATION

• To use multiple extract tool on the class A surface
• The extract boundaries can be sweep at 90 degrees to the reference boundaries up to required length

TREE STRUCTURE

CLOSE SURFACE

VARIOUES VIEWS OF COIN HOLDER

CONCLUSION:

• To use class-A surface and create Tooling axis, Draft analysis were performed.
• The solid component was created from the surface model.
• The class A surface provided in the challenge has no hole and cat part cannot open.
