Door Arm Rest Week 8 Challenge

AIM: To create a door arm rest from the given class A surface.

OBJECTIVE:

1. To create a tooling axis for the given class A and analyize whether a side core is required.
2. To create a class B surface.
3. To create a class C surface.
4. To create a part by joining class A, B and C surfaces and perform a draft analysis on the part.

DOOR ARM REST

A door arm rest is the part on the door where arm or elbows are rested and also sometimes used to open the door.

Fig 3: Class A surface of door arm rest

Fig 4: Class A surface draft analysis along main tooling axis

Surfaces which are not cleared in main tooling direction will be cleared with a side core/slider direction.

Fig 9: Part model draft analysis along slider direction

Fig 10: Part model draft analysis along main tooling axis

Walls or surface not cleared by the main tooling axis such as faces in red are cleared by side core or slider as shown in figure 9.

CONCLUSION

Hence a door arm rest is designed from class A surface and a draft analysis is performed on the part.
