Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1

Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1

Aim

1. To create the Door Handle Component from the given Class A surface

2. To Create the the tooling axis for the given Class A surface meeting the requirement of Draft angle.

3. To Attach B side feature in the component.

4. Create the rib for the Drill Handle considering the design rules

1. Creating Tooling Axis -

The Tooling Direction is basically the basically the direction that the mold pulls a part. The mold is built in in two seperate pieces, basically . You have a Cavity side and you have the Cove side . The core pulls apart from the cavity and thats the Dye line or the Tooling Direction.

1. Open the given CAT part file.

2. Check for gaps between the surfaces for that click on join and then preview.

3. If theres any gap between the surfaces join them with a maximum tolerance of 0.003mm.

4. Extract the boundary and dissemble the boundary.

5. Find the correct tooling axis where the material dont interfer with the tooling axis and all the elements can be created .

6. Created an axis system using at the centre of the switch bezel.

7. Intersect the yz plane with respect to class A surface.

8. Hide the class A surface and create point to point lines on the suspected drafts.

9. Create bisecting line with the two lines and point to create a tooling axis.

10. BISECTING LINES were used to get the exact medium from the two sides so that maximum positive draft angle can be achieved.

11. The Tooling axis is created the component by bisecting two axis from x and y planes.

To making a close surface we have to create a class b surface. i am offseting the given part inside in 2.5mm and fill all the patches and making c surface using with the swept option.When complete making all the surfaces then we have to using join and trim option to make a close surface.When the close surface done then we have to move in screw boss and ribs.
