Week 9 - Project - Master Section Development
AIM :
To design a B pillar with the given mastersection.
MASTER SECTION:
Mastersection helps you to do decide the fesibility the clearance,packaging,and the fixation stratege of component before bucking it into the component.mastersection are the guide for design recuriments which decide the component packaging after techinacal surface.
PROCEDURE:
1. Check the given class A surface whether there is any patches are any missing surfcae after clearing that join the surface properly ones its done check the surface properly closed or not by using boundary tool.
2.Create tooling axis by using mastersection use bisecting option .
3.By using class A create B surface. extracte class A to create B surface and offset to 2mm.after B surface over take boundary in class A to create flanges in both corner of the surface by swept tools and compare the flanges with mastersection.after flange created to class A create flange for class B also and filled it.
4.After B surface generated .c surface has to be developed in the class A surface using the sweep option and draft angle should be 3deg direction along tooling direction selecte draft angle outside.
5.After c surface created join with class A with flange and trim it and make a singe surface .
6.After trim join B surface to get B piller part.use boundary to check it close or not onces its done insert body -> closed surface .after the creation of closed body check draft analysis along main tooling direction.
DOG HOUSE,LOCATOR AND RIB CREATION:
- 3:1 ratio of steel width to height.But 2:1 is preffered.
- Minimum wudth:3:1 ratio of steel width to height.But 2:1 preffered.
- Draft: Minimum 1.5deg.
- Inorder to avoid sink marks:height (c)=40%of nominal thickness.Width(B) =3.0mm-6.0mm.
7.After developing dog house thick it 2mm.the inside part will not be drafted with tooling direction so that side core has to be created and draft it with side axis direction respectively.aplu chamfer,fillet.
8.By using dog house plane create locator on the top surface ,pad it along tooling direction use netural face.finally chamfer,fiilet it.
