Week 9 - Project - Master Section Development

GGuru Prasad28 Feb 2022

OBJECTIVE

Create b pillar of a vehicle from the given class A input and devolop the part by using master section to create ribs , flanges , dog house , locators .

creation of tooling axis

tooling axis decides the movement of the core and cavity during injection moulding process ,

lifter axis is the axis in which the side core movement takes place ,

MASTERSECTION :

These are the guidelines provided to a design engineer which describes how a component would / must look like once it is modeled into a solid component from the class - A surface . For example , in this model we have received master - section as an input which tells us about the thickness of the component and dimensions & type of the engineering features on the component .

draft analysis for class a surface

class b creation

from the given inputs , the class b surface is created by making the direct offset of the given class a surface ,

but it dosent create a perfect offset , so we must work on the missing patches to design a proper class b surface

Devoloping the flanges

flanges are devoloped for both the class A and class B surface , while offseting the flange for the class b surface , it creates missing patches in the surface , it is devoloped by using the multi section command and the flanges are added to the class a and class b surface ,

devoloped flange

creation of class c surface

the class c surface is created by taking the boundaries of the part and the smoothening it , finally they are sweeped by using the tooling axis with a minimal draft of 3 degrees ,

designing dog house

These are the design rules to be followed while designing the dog house
