Door Arm Rest Week 8 Challenge

Tooling Axis :

The base surface or bace from the pocket from the Door arm rest class A Surface is extracted and tooling axis is created normal to the surface. The point for the tooling axis is created by extracting boundary from the base hole and an arc is created scince the extracted boundary is discontinuous, using the third point created on the extracted boundary using ratio as 0.5 .

Slider Axis :

The side face of the door arm rest class A surface is extracetd and un trimmed and a point is created on the surface. A line is now drawn normal to the surface which acts as the slider axis.

Offseting Class A Surface :

The class A surface is offseted to a distance of 2.5mm as per the design parameter.

Removing side ribs :

Generally in door arm rest any inward ribs can ot be creaed and there is a surface which has not been extrapolated.

Removing the ribs :

The ribs from the backe surface is removed by using join sub elements to remove command.

Class B Surface :

The fillet surface on the bottom is created using multisection selecting the side edges as profile and the edge of the base as guide. Then the remaining portions are filled using fill command.

Now the edges of the created offset is extrapolated and is named as class B Surface.

Boundaries :

Boundaries are extracetd from the class A surface and is curve smoothened using curve smooth command with curvature value as 0.001mm.

Class C Surface :

The smooth curve is sweept using sweep ----> Line type -----> with reference surface -----> 90 deg angle (5mm sweep length). The edges are joined to form the class C surface.

Joining A & C surface :

The class A surface and class C surface are joine using join command.

A,B & C Part :

class C surface is trimmed with the A & C surface join to create the final part of A, B & C surface trims.

Final Part :

After joining all the faces there will be a surface left to fill in the bottom.

The class B surface hole is filled and the Class A surface hole is extrapolated then is trimmed to form the final part or final surface.

Final Surface finish of door arm rest :

Part body conversion :

The work bench is changed to part body workbench from surface design work bench. Using clossed surface command the surface model is converted into solid part body.

Draft Analysis :

There is lots of deviations and corrections to be done with the class A surface which has to be done by the surface A designers. Part body is created for the given surface and draft analysis is done and submitted.
