Week 8 - Challenge 3 - Coin Holder Design

COIN HOLDER

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.

objective:

• Tree Structure
• Ensure Proper Tree Structure
• Geometrical sets should have a proper name based on the sketches present inside of it
• All the sketches should be created under the Geometrical set
• Use the Close Surface feature to make a solid body from the surface.
• Publications: Use the publication option and publish the below
  • Tooling Axis
  • Class A, B, and C surface

Introduction:

CLASS-A SURFACE: the class-A surface is used in the automotive design industry. it describes the final production surface data for the aesthetic parts.

CLASS-B SURFACE: the class-B surface is the second surface that has a certain thickness from the class-A surface. this surface contains engineering aspects of a model. These must be smooth and "error-free" as well but are not held to the standards that class A surfaces are.

CLASS-C SURFACE: The Class C finish allows more imperfections than Class A or B. Class C is often specified for interior surfaces not readily visible, surfaces that will be covered by another part when assembled, or surfaces.

Draft analysis:

Draft analysis is required to check if a part has required draft or not. Draft is required so that a part can be ejected from its mould.

Design procedure:

STEP1: Checking Class A input for imperfections.

The input Class A surface is checked for discontinuities and joined together to get a complete Class A surface as one.

STEP 2: Find the tooling axis of the component. The tooling axis is nothing but the mould opens or cavity opens.

• Check visaully which is the best possible tooling axis.
• y is the best possible tooling axis.

Creating a Tooling axis along y:

extract the bottom surface then hide class A surface and create line with normal to surface method.

Now perform the Draft analysis using the Featured Draft Analysis tool in the tools.

Then after opening the draft analysis tool box go for the compass and place the compass alinged to tooling axis and click on the lock symbol after alinging and further click on the surface.

STEP 2:

Now creating Class B Surface:

Intially extracting the flat surfaces using extract option from Class A surface.

Then perform Untrim option:

Then Offset the surface inorder to get the required thickness:

Then perform Extrapolate inorder to increase the length:

Now trim the surfaces to required surfaces:

Now fillet the surface to required amount:

STEP3:

Now Creating Class C Surface:

class A surface take boundary and sweep the draft angle

and the last process trim the class A,B and C surface then get the final product

Now convert solid model

In the method closed surface method

MATERIAL:

Polypropylene

Polypropylene is a saturated polymer that is created from the monomer, propylene. One of the major benefits that polypropylene has to offer is that it is resistant to acids, bases, and chemical solvents.

Its applications can be found in gas cans, carpet fibers, bumpers, cable insulation, and chemical tanks.

CONCLUSION:-

Finally the Class – A, B&C surfaces with the Tooling Direction have been Published and the Switch Bezel is moved on to the designing of the next operation – the creation of B-side features.
