Week 9 - Project 1 - Door Trim Lower with Engineering Features
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 4way tool and Heat stakes
the given class A surface....
*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, belnd option or by extracting the classA Surface.
*How to create tooling axis….
-Create a point at the base OR any flat surface from where we can se 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
here u can see some gaps were created automatic when we take the offset of class A surface.
after filling the gaps the ceated b surface.....
HOW TO CREATE CLASS C SURFACE…..
You can 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.
HOW TO CREATE A CLOSED SURFACE
Join these Class C and Class A surface.
Now you can trim that joined surface and class B surface….
Now you have a close body of the DOOR TRIM.
now this is the solid body......
CREATION OF 4 WAY AND HEAT STAKES AND GIVING THEM DRAFT ANGLE TO 0.5 DEGREE:
-Locator Design...
-Create sketch by taking extract of the solid part surface as reference.
-Sketch up to certain limit and use design rules as per rip design.
-Use 0.5 degree dropped with pulling direction as tooling axis.
-Give entry chamfer
-Give fillet
-Union trim with door applique
-Use translate command of no. Of same locator....
Heat stakes design...
-Use point and plane reputation command for points on the curve.
-Create sketch by taking door attachment class a surface as reference
-Add the sketch up to certain limit and used design rules as per screw boss design.
-Use 0.5 degree draft with pulling direction as tooling access and give fillet.
-Union trim with door applique
-Use translate command for number of same locator
the heat stakes are in yellow coloured....
the 4 way is in pink coloured
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.
