Week 9 - Attachment Feature Creation - Challenge 2
Design of DOOR TRIM with the help of CATIA V5
*Objective:
* To design DOOR TRIM with respect to the class a surface.
*Create class b surface and class c surface and the tooling Axis.
*Convert those class A surfaces in a close body and make it into the solid body provide the thickness of 2.5 mm
*Performing draft analysis to verify the creation of tooling axis and class C surface.
*To Create a DOG HOUSE for screw boss at two position.
THE CLASS A SURFACE IS MENTIONED BELOW.......
*Here we are using the software catia v5 generative safe design…
.Design methodology with images.
HOW TO CREAT B SURAFCE OF THE DOOR TRIM....
Select the whole class A surface and take an offset mode by 2.5mm at inside.
Now you can see some gaps are present in the offset surface….
You can fill those gaps by using multisection option, blend option or by extracting the class A Surface
THE CLASS B SURFACE AFTER FILLING THE GAPS....
HOW TO CREATE CLASS C SURFACE…..
You are not allow to give direct sweep option by 90 degree in this case…
Because in this case there are more curved surfaces are available you can not direct extrapolate that surfaces.
So you have to take individually extrapolate that curved surfaces and flat surfaces by giving 90 degree + some draft angle.
THE CLASS C SURFACE......
HOW TO CREATE A CLOSED SURFACE
Join these Class C and Class A surface.
Now you can trim that joined surface with class B surface….
Now you have a close body of the door trim.
HOW TO CREATE A SOLID BODY….
You can make a solid body of the door trim by using that closed body….
Go through the part design> closed surface> select the closed body.
Now you have closed body of the door trim…
How TO APLLY DRAFT ANALYSIS…..
-Procedure of creating draft analysis
-Go to insert menu and select the analysis option
-Select feature and draft analysis
-Select the material option and select the surface
-Drag the compass and place on tooling axis
-make sure that the top surface is in green colour as draft angles should not exceed 3 degree.
*How to create tooling axis….
-Create a point at the base OR any flat surface from where we can see max no. of surfaces from the class A surface.
-Extend the line at that point which is perpendicular to the plane or surface
Chane the colour of that line and make it as construction geometry
-Rename it as tooling axis..
Drawing analysis of DOG HOUSE:
-C is where the dog house contact the backside of the surface
-Dog house wall thickness at the intersection of the part wall C should be 40% orless than the main wall stock T.
-The height of B should be 3 to 6mm
