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 SURFACE:

TOOLING AXIS:

• Tooling axis can be classified into two methods

1. 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 ANALYSIS:

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

• Using this command, the compass was set on the main tooling axis and the Draft angle was changed to 3 degrees.

CREATING CLASS-B SURFACE:

1. SIDE WALLS:

• 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

3. BASE:

• To create a base by extract the base from class A
• To untrim and extrapolate the base for final trim to create a B-surface

TOP WALLS:

• To create a top wall by Mutiple extract the class A side faces
• To extrapolate them for up to requirement
• To offset the walls up to 2.5 mm

BEFORE FINAL TRIM OF CLASS B SURFACE:

AFTER INITIAL TRIM:

OUTER FLANGES:

FINAL TRIM:

B-SURFACE:

B-SURFACE

CREATING C- SURFACE:

• 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

C-SURFACE
