Week 9 - Project - Master Section Development

MASTER SECTION DEVELOPMENT

We have been provided with a class A surface of B pillar and master section for the development of B Side features.

At first we will be creating solid part and then developing the B Side features as per master section.

MAIN TOOLING AXIS

The main tooling axis is given as per core and cavity for the main part to clear drafts for main part.

LIFTER TOOLING AXIS

Lifter tooling axis is provided to dog house as it cannot be cleared in main tooling axis.

CREATION OF B SURFACE AND FLANGES

To design B surface we have used different tools like Multiple extract, smoooth curve, extrapolate, offset, trim or split etc. as per the requirement for devloping.
Designing of flanges on both B and Class A surface.

CREATION OF C SURFACE

The class c surface is developed to join Class A surface and B surface and create a close body which can be further converted into solid body.

RIB DESIGN RULES

DOG HOUSE DESIGN RULES

"C" is where dog house contacts backside of surface.
Dog house wall thickness at intersectionof part wall (C) should be 40% or less than main wall stock (T).
Height (B) should be between 3.0-6.0 mm.
Minimum height of dog house is 6mm. Less than 6mm causes weak steel condition.
Mininmum draft for dog house is 1.5 to die draw.

Ribs and dog house has been designed as per the master section provided.

DRAFT ANALYSIS

There is a red colour at the edge that is because of the error in Class A surface.

The minimum angle at the red location is -1.55 degree.
