Door Arm Rest Week 8 Challenge

Door Arm Rest Design

AIM:

To design a door arm rest design using given Class A surface.

CHECKING QUALITY OF CLASS A SURFACE:

Checking a class a surface using a command of boundary command there is any opening patch a surface locally.

FINDING MAIN TOOL DIRECTION:

To find tooling axis I am using method of TRAIL & ERROR method

1. First I am creating point on center of the part using command of measure inertia
2. After creating line and find a tooling direction by rotating compass.
3. And locked the compass position and creating line (TOOLNG AXIS)
4. Ref below image green color area are 3deg above and red color area having 2.92 deg.
5. In this condition this part not required side core and any mechanism.
6. All area releasing core & cavity

DRAFT ANALYSIS A CLASS A SURFACE:

CREATION OF CLASS B SURFACE:

1. Creating a class B surface using command of extract ,multiple extract
2. And untrimmed the surface to each surface
3. Fillet are not consider in this condition

CREATION OF CLASS C SURFACE:

• Class C surface area creating a command of sweep with direction & sweep with ref surface

multi section surface, fill commands.

MERGE A SURFACE CLASS A,B,C:

• Merging a class A,B,C surface are merged together to get sold model.

DRAFT ANALYSIS A SOLID MODEL:

Green color highlighted area having 3deg and above.

Some Red color area in cavity side draft having range of 2.5-2.92 deg.

When texturing surface required min 7 DEG required.

CONCULSION:

Door arm rest design completed using CATIA V5

In this part not required any mechanism like side core, lifter all area releasing core cavity direction.
