Week 9 - Project - Master Section Development

AIM:

To create a solid body of B pillar cover including ribs and locators by using given Class-A surface.

OBJECTIVE:

• Tooling Axis creation
• To create B surface
• To create a C surface
• To create a solid part
• Draft analysis
• Create a dog house
• Create a 4-Way locator
• Create a Rib.

GIVEN CLASS A SURFACE:

First I need to check whether the surface has some boundary irregularities and any open boundaries.

Tooling axis creation:

The Tooling Direction is basically the direction that the mold pulls apart. The mold is built in two separate pieces, basically. You have a Cavity side and you have the Core side. The Core pulls apart from the Cavity and that's the Dyeline or the Tooling Direction.

• analyzing the model visually to see the most efficient side suitable for the tooling axis from the image below image.

By taking the intersection line between the 4-way locator by bisecting lines to form a Tooling Axis.

CREATING CLASS-B SURFACE:

By Offset the Class-A surface by 2.5mm to form a class-B surface.

By using multiple extracts create the boundary to create sweep and extrapolate the corner surface to trimming with sweep and form Final Class-B surface.

By extrapolating the edges from class B.

Extrapolating the opposite corners.

Creating a boundary using multiple extracts it gives more edges to avoid edges we need to convert multiple extracts to smooth edges.

Now create a sweep to form a flange on both sides.

After sweep trim the flanges and extrapolate to form a final out put of the class-B surface.

Creating Class-C surface:

By extracting the boundary from the Class-A surface required for class-C surface. sweep the boundary with respect to the class-A surface, and trim Class-A with a sweep to combine, next trim class-C surface with the class-B surface to form the final output.

Now sweep the all boundary to y-direction ane angle always turned inward drafting.

after trimming the all sweeps with class A to form class C surface.

To form A final output we need to trim both Class-B and Class-C surfaces to get the final output.

Final output:

After getting the final output goes to Partworkbench to convert the closed surface.

Drafting Analysis of the Final output:

• After creating the solid body we will perform the draft analysis of the whole part body.
• First, change the parameter to material mode and then go to perform draft analysis Go to Insert > analysis > feature draft analysis.
• Click on the compass icon & align with the tooling axis.

Creating a Dog house:

Extracting the Dog house boundary from curve-3 and extracting the line towards the plane.

Extract the lines from Curve-4 and extrude the lines towards the y-direction.

Thicken the extracted surface to form a solid dog house.

The draft should be at 0.5Degree

DESIGNING OF LOCATORS:

What are locators?

Locators work as The 3-2-1 principle of location (six-point location principle) is used to constrain the movement of the workpiece along the three axes XX, YY, and ZZ. This is achieved by providing six locating points. There is a total of 12 degrees of freedom, 6location, and 9 translation.

In this, I need to fix any 11 degrees of freedom permanently and anyone to be clamped or fixed temporarily.

4-Way locators

Taking the reference From Curve-3 And 4.

Thick the line from pad commends for 0.8mm(40% wall thickness of 0.4*2mm)

Chamfer the edges around 45*5mm

Drafting every face around 0.5Degree

Add the locator to the Dog house using Boolegen untrim.

Drafting Analysis on dog house assembly:

DESIGNING OF RIB:

Creating the rib as per design rules given the draft angle and fillets.

Thicken the surface by 0.8mm as rib
