Week 10 - Challenge 3 - Door Trim Lower with Engineering Features

1. Draft analysis :

We have to make draft analysis for given CLASS A surface with 3 degree draft angle by creating a point on the flat surface and draw a line and naming its as a tooling axis checking drat analysis images attached below

2. Closed surface :

After checking draft analysis we have to make surface as a closed surface by creating B SURFACE with off set of 2.5mm thickness after that we have create C SURFACE with help of sweep tool .Creating of C SURFACE by joining of A SURFACE and SURFACE .After that we have extrapolate the B SURFACE with intersection of A+C surface .finally we make trim of B SURFACE AND A+C SURFACE we can get the result of closewd surface. Inserting part body creating solid part in the part work bench solid body shown below ..

3.Draft analysis of closed body :

After completion of solid body we have to check draft analysis of the solid body as we did before for the surface of CLASS A surface .The image of closed body draft analysis is attached below .

4. LOCATORS AND HEAT STAKERS :

Locators and heat stakers are used to arrest the 12 degrees of freedom of translational and rotational motion of X,Y,Z, axis .There is the gap between locators and heat stakers its about minimum 15 mm to 20mm maximum .The height of the heat stakers must less than the locators .Heat stakers also know as the plastic welding.There are two types of locators 4 way locators and 2 way locators . Heat stakes have to create almost 10 to 15 heat stakes and locators 3 to 4 loactors have to be create. Finally add heat stakes and locators in the part body the completed image of heat stakes and locators are attached below .
