Week 9 - Project - Master Section Development

 

Master Section Development:

* Here we have a master section of 2 components dog house and 4 way locators.

* The input is a CLASS A and we have to develop CLASS B and CLASS C from it.

* Inspect class A surface without having any discontinuty.

* By using the master sections find the tooling axis by taking the nearest point and form the lines from it then use the                 bisection method and find the tooling axis.

* Use the same method for the lifter also to clear the dog house.

* so, that now we have 2 tooling axis main tooling axis and lifter tooling axis.

* Now form the B surface and C surface.

* Do the draft analysis for the class C surface.

* Take the master section for the reference and create a profile for the DOG HOUSE.

* Again take the master section as a reference and create a profile  for the 4 way locator.

* While forming the DOG HOUSE and 4 WAY LOCATOR follow the all design rules.

* The C surface should have minimum 5 deg of draft and attached parts like DOG HOUSE and 4 WAY LOCATOR should have       0.5 deg of draft.

* Form the ribs to give the strength to the part.

* Each RIB should have 50mm distance and give the draft to each RIB.

* Finally assemble the all components and make it into single component.

* Check all the analysis and error portions like high draft and low draft areas should be highlighted and show the value of         that  pirticular portion.       

NOTE:

1. Make sure that all the profiles should be iso-constrained.

2. Each and every 4 way and 2 way locater should maintain the approximately equal height.

3. Heat stakes should be lower then the locators

4. Each heat stake should maintain minimum 50mm distance from each other.

5. Clearence should be given to the heat stakes and locators and it does not have any design rules but should be maintain          design  rules without forming the sink marks.

6.Maintain the draft angle for the heat stakes and class c surface.

7. As class C  surface is a flat surface we can take the tooling direction directly without using any bisecting methods.
