Week 10 - Challenge 2- Attachment Feature Creation (Dog House)

DOOR HANDLE TRIM (STEP USED):

Thickness:2.5mm

Tooling Axis creation:

To create Tooling axis, i have extract the bottom surface and axis create with using bisecting methed.

After createing tooling axis i have to draft analysis to verify the draft direction for the matrial flow on mold.

B Surface Creation:

Then to create class B surface creation,

• Firstly I have extract all flat surface then untrim each then trim the all untrim surfaces
• Then provided fillet at all corners with input of class A fillet with addition of component thick.

C Surface Creation:

• To create C Surface i have use sweep on the boundary of the class A.
• I had use draft direction sweep and reference to the surface sweep to create the C Surface.

C+A Surface:

I trim the class A with C surface to create C+A Surface.

Final Trim:

To create final closed surface, I had trim C+A surface with B surface.

Draft feature analysis for Final Trim Body:

Solid Body Creation:

Used closed thicken tool for create thicken the closed surface.

Dog House Creation:

I used the above design rules to create Dog House draft calculations,

To create Dog house

Dog houses are purpose to avoid sink mark created on the CLASS-A surface by screw bosses and to solve the length issues when giving screw bosses which need to be assembled to other components.It is also useful when perpendicular screw bosses are required on the part to the tooling direction.

The following steps are followed to create the Dog house,

• First step is to create a side core axis.
• I have chosen the normal to-the-point method for creating the side core tooling axis.
• Create the dog house by creating a positioned sketch on the z-x plane.
• Using extrude or sweep method create dog hose outer walls.
• Now close the top wall using the multi-section surface command.
• Using thicken command in the part workbench, create a solid part of the dog house.
• Give proper draft angles and fillets by considering the design rules.
• Boolean operation, union trim and split the dog house body part with the door trim component.
