Door Arm Rest Week 8 Challenge

AIM: Creating the Door Arm Rest component through the given Class-A surface of 2.5 mm thickness with the tooling axis meeting the requirements of the draft angle and at the end performing the Draft analysis on the model.

PROCEDURE REQUIRED DRAFT ANALYSIS:

STEP 1: Ensure there is no gap between the two neighbouring surfaces.

Operations Boundary definition>select component

STEP 2: Tooling Axis: Tooling axis is the direction in which mold or core and cavity is opened.

We have to check all possible tooling directions in all the three axes. When we are deciding the tooling axis we have to make sure that all the faces should be visible to that tooling axis, no face should be hidden.

For this component the Z axis will be the best tooling axis as we can see all the faces of the component and can be cleared in the x and y axis direction.

STEP 3: To make tolling axis for this model we have to follow following steps

• Create a point on the curve of the circular portion.

PROCEDURE FOR DESIGN:

STEP 1: Extracting Surfaces from base of door arm rest.

Schedule a counselling session

. Extract the surface

. Untrim that extracted surface

• Trimming surface.

Offset it inside to 2.5 mm

Extracting Surfaces from the first half surface of door arm rest.

Extracting Surfaces from the second half surface of door arm rest.

 

• Trimming all three B surfaces.

 

Giving outward and inward fillet radios, where both half bodies are joining

STEP 9: Extracting Sweeps from all the boundaries of A surfaces.

• Multiple extracting edges of A surfaces.

Smoothing the curve of multiple extracted lines.

• Sweeping smooth curve with sweep with direction panel.

• Extrapolating corner of the edges.

Trimming it in desired output.

Joining all sweeps together.

Join the final trim (sweeped surfaces) and A surface.

We can see the thicken C surface after trimming as below
