Week 9 - Challenge 2 - Switch Bezel Design

Aim: Create the Switch Bezel Plastic component through the given Class-A surface.

Objective:- The objective of the project is to design the switch bezel and to do a draft analysis for it by creating the required tooling direction with the help of Bisecting method.

DESIGN CONSIDERATION:-

• Class – A surface should be aesthetically smooth and good.
• Class – B surface should have all the supporting features like ribs.
• Parting Line should coincide with the B surface since flashing couldn’t affect the aesthetic of Class – A.
• Class – C surface should also pass the draft analysis.

PROCEDURE FOR CREATING SWITCH BEZEL:-

• First, the given styling surface is checked for any irregularities, and if found then it is corrected by using Trim, Extrapolate, Split, and Join commands.
• The below image shows that the Class A Surface is clean and no irregularities present, so let's move on to the next step.

CREATION OF THE TOOLING DIRECTION:-

• Considering the Ejection from the cavity of the mould after manufacturing the interior trim (switch bezel) must have a nominal 3-degree draft angle.
• Hence the tooling direction is created by considering the above factor and bisecting method is used.
• The base surface of the class – A was extracted and a point at the centre is created and an axis system was inserted to the point with the current feature is disabled.
• Then, using project intersection along yz plane is created and the two inclined lines were drawn inside the positioned sketch.
• Then bisecting lines with the two inclined lines were drawn.
• Now the same procedure is done along the xz plane but on one side we don’t have inclined lines so the centre point is used to extrude a line along the z-direction and gave a measurement of 5 degrees (Tentatively).
• With these two lines from sketches 1 and 2, the bisecting line is created and published as Tooling Axis(tooling direction).

conclusion:- Hence the Surface modelling was done with the given dimensions were Class B and C and also Draft analysis was done with the given modelling and it was attached below.
