Week 9 - Attachment Feature Creation - Challenge 2

Design of Door Trim & Dog House

Objective :- We have to Create close Surface from given Class A Surafce and create attachment features Dog House On it.

Step1. Tooling Axis Creation:

For, Tooling Axis We Use Bisection Metod, for that we extract One Surface and Create Point On it and after that we create two more lines and use Bisection method to create one line and get Tooling Axis .

Draft Analysis For Class A

After creating of Tooling Axis We will do Draft analysis with given Class A Surface at 3 deg.

B Surface Creation

For B surface creation we will offset given class A by 2.5mm on Inside direction . After that We will get Patch up Area on it and We will Remove the Patch Up Area.

1st Surface Creation :

For 1st Surface Creation We will Use Extract, Offset, Join & Multiple Extraxct. We will firstly remove patch up Area of Base .

2nd Surface Creation:

For 2nd Surface Patch we have to use Extract, Join, Mutiple Extract, Boundary, Extrapolation & Trim. After that We Will get removal of 2nd Patch Up area.

We Will remove all the patches area by using Boundary, Multiple Extract, Trim, Untrim & Join . After Removing all Patches We Will get B Surface.

C Surface Creation :-

For c Surface We will Use Boundary, Sweep with Reference Surface , Extrapolate it , Trim it & Join it we will get Final C Surface.

Final Surface :-

We Will Trim B Surface with C Surface after that we will Join with A Surface and we will get final Surface.

Close Surface :

After that we will go into the part design and Change our final Surface into Solid .

Dog House Creation :

Sweep Surface:

We have to extract one surface from class A surface , after that we will offset it for 2.5 mm create one point on it and take Zx plane on that Point after that we will Create Sketch On it and sweep it on Internal Direction for 1.5 deg and 20mm.

We will create one line by point & point and extrude it and trimed it with sweep surface . We will get the surface.

Thick Surface :

After that we will go into the part Design and convert it into the thick Surface of 2mm.

Side Core Tolling Axis:

After that we will Create Tolling Axis for Side Core Area . So We will Extract One Surface create Point On it and Create line by Point and Direction Method .

After that We will Provide Draft of O.5 Deg and Material Should Cutted and Pulling Direction is side Core Tolling Axis.

Split Surface:

We will Create One line at the Bottom and Extrude it, after that we will Offset it for 5mm and Extract One face of thick Surface with Tangent Continuity Extrapolate Both the Surface and Trim it. We will Create this Surface within 3mm to 6mm.

After that We will Split Thick Body with Trimed Surface.

Edge Fillet :

After that We will give Edge fillet to Dog House Part. And Our Final Model of Dog House.

Calculation Part:

Draft Angle = 0.5 Deg

Edge Fillet Inner = 1mm

Edge Fillet Outer = 3mm

Thickness = 2mm

Height of B to C = 5mm.

Draft Analysis For Dog House:

First we will Do draft Analysis for Dog house with Main Tooling Axis in 1.45 Deg.

After that We will Do Draft Analyis for Internal with Side Core Tolling Axis.

Draft Analysis for Final Model :

Model:
