Week 9 - Project 1 - Door Trim Lower with Engineering Features

AIM : Create the Door Trim Lower Plastic component through the given Class-A surface. Create the Heat Stakes and the locators considering the design rules mentioned in the video for the door applique.

OBJECTIVES :

1. To check continuity of Class A surface.
2. To create a tooling direction.
3. To perform draft analysis of the plastic component.
4. To create Class B and Class C surface using Class A surface and make a closed Body.
5. To create the heat stakes and the locators considering the design guidelines.
6. To perform the Draft analysis on the final component.

CLASS A :

CONTINUITY :

Checking for continuity in Class A surface using boundry commmand.

As there are no gaps we can move further.

TOOLING DIRECTION :

To create the tooling axis, I extracted a surface from class A and created a point in the middle of the surface by using the point command and created a line at that point through the x-axis.

CLASS B SURFACE :

For making of class B surface Class A is offseted at 2.5mm. After offseting Class A surface we see there are some patches on offseted surface these are due to fillets in Class A surface. So this patches are covered by extracting the boundry of the patch to be cover and using Multi-sections, Swept command.

AFTER FILLING/COVERING THE PATCHES/GAPS.

C SURFACE :

Class A-Surface and Class B-Surface are connected by C-Surface. The command Sweep is used to construct it. The class A surface's boundary is Extracted and swept at a 90 degree angle to make Class C surface.

JOINING CLASS A AND C SURFACE :

FINAL JOIN :

Joining all the surface with each other.

HEAT STAKING :

Manufacturing operations currently use many different combinations of attachment methods to keep components together. Common fasteners such as bolts, screws, and rivets can be used to form permanent attachments, but there are attachment methods that don’t require secondary hardware. One of those methods is heat staking, which doesn’t require additional fasteners.

4 way Locator :4-way mean you prevent movement at 2 axes (+X, -X, +Y and -Y) on the plane.

I have chamfer the four corners to 3mm with 45 deg angle. And given 0.2mm fillet to the edges.

HEAT STAKES :

The supoorts are chamfer 3mm with 45 deg angle and filleted to 0.3 mm to all the edges.

DRAFT ANALYSIS :

Heat stakes and Locater are drafted and given the angle of 0.45 deg.
