Week 8 - Challenge 1 - Base Bracket Design

AIM - Create the Base Bracket Plastic component through the given Class-A surface.

CLASS A SURFACE

STEP 1 - Check the connectivity/continuity of the surface using the boundary tool or the close surface tool.

Step 2 - Creating TOOLING AXIS

• Check the best tooling direction by visualy considering the cost factor in mind. Here the best tooling direction is Z direction because if taking the x direction it is costly and if i take y direction it contain so many problem making surafces.
• A point was created at the center of the large circle, Using that axis system is inserted. Make a intersect between the yz plane and Class A surface

• Creating the TOOLING AXIS by bisecting the two lines. And the result is the tooling axis (yellow colour line ).

[ TOOLING AXIS - The direction in which mold open and close or simply say that tool movement axis.It decide the draft direction]

STEP 3 - DRAFT ANALYSIS for CLASS A

• Draft angle is 3`degree`

Step 4 - Creating the CLASS B surface.

• Extracting the surfaces from class A ,then Untrim and Extrapolate
• Offsetting the extrapolated surfaces and trim the offseted surfaces , then we got a Class B surface that is 2.5 mm below the CLASS A

Step 4 - Creating the CLASS C surface.

• By using the sweep and tooling axis we got the CLASS C SURFACE.

STEP 5 -

• Joing class A Surface and C Surface

STEP 6 - CLOSED SURFACE

• Trim the final joined surafce with CLASS B Surfcae

STEP 7 - Creating solid from closed surface

• Using the Close surface tool in part workbench.

STEP 8 - Draft Analysis for Part
