Week 8 - Challenge 3 - Coin Holder Design

AIM: To 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.

GIVEN SURFACE A:

COIN HOLDER CAT PART

COIN HOLDER IGES

COIN HOLDER STEP FILE

CLASS A 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

TOOLING AXIS:

• Tooling axis can be classified into two methods.

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:

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.

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.
