Week 10 - Challenge 2- Attachment Feature Creation (Dog House)

Aim: - To create a DOG HOUSE on given Plastic Component through a given Class A Surface and perform Draft

Analysis on the final plastic component.

Objectives:

• Creation of Tooling Axis.
• Creation of Class B and Class C surface.
• Creating a solid part out of surface modelling.
• Creating Dog House on the component.
• Draft Analysis of Class A surface, final plastic component and the Dog House.

Provided Class A surface for component is shown below:

Identifying Tooling Axis

· On inspecting the part, the Y-Axis is the best option for tooling the component.

· As shown below the Tooling Axis is created using Normal to point method.

Draft Analysis of Class A surface is shown below:

· To manufacture the Tooling component, Draft analysis is done on it.

· Industrial std. is of 3° and as it is seen in the above the draft on provided class A surface is more than the acceptable value.

Creating Surface B

· Using extrapolate and off-set command the surface B is created which is shown in below image of off-set value of 2.5mm.

Creating Surface C

· Using Boundary command, the Class C surface is created as shown below:

Final Tooling Surface

· Now using Trim command all the excess surfaces are trimmed and required final surface is formed as shown below:

Converting to Solid Body

· After completing the Final surface, shift to Part Modelling interface, now using Closed Surface Command the whole Surface body is now converted into solid Plastic Component.

Draft Analysis on Final component

· As shown below the Draft angle is under well acceptable range for the Final part which is 3°.

Dog House Creation

· Now using part modelling the dog house is created and an extra Tooling Axis is created for the draft analysis.

· From the below image it is clear that the draft analysis of the Dog House 1 & 2 is well under acceptable range which is 0.45° for inside & 1.5° for outside .

Following are the different views of final model along with Tree Structure

Following is the required Tree Structure for the Component:
