Week 8 - Challenge 2 - Switch Bezel Design

STEP 1- CREATION OF TOOLING AXIS

• A new axis system and reference point are established along Surface Zero.
• Tooling direction was created by using the X direction and Y direction along Class A.
• After cutting the two lines in half, the Tooling axis is formed and published. Using surface operation commands, take a Class A Surface as input. Class B has been created.
• The Class C boundary swept with draft direction is determined by the tooling axis.
• All drafted parts should be visible when viewed normally from the tooling direction to provide a general concept of how an injection-molded product is manufactured.

STEP 2- CREATION OF CLASS B SURFACE

• Designing B surface for the input, which is typically the surface where all engineering considerations and support constructs are made, is the following phase.
• In CATIA, surface operations are used to create the B surface, which differs from Class A in that its dimensions are proportionate to the part's thickness.
• The thickness of the component, 2.5mm, is offset from the input by the B surface of the switch bezel.
• The bottom skin of the portion is made up of the B surface, which is extrapolated in relation to the A surface.

STEP 3- CREATION OF CLASS C SURFACE

• The C surface, an intermediary surface between A and B that is employed to give the design a closed surface appearance, is the next phase.
• The Guide curve with a subtype along the DRAFT direction is used as the boundary line of Class A, and the profile is used to sweep the C Surface.
• The tooling direction established earlier determines the sweep's direction.
  A 3-degree draught angle is given for the sweep operation, and the surface is swept for a length above the designated part's thickness.
• The complexity and spots along the swept surface are removed from the C surface utilizing the smooth Curve choices.
• In the end, the Class A and Class C surfaces are merged, and the connexity of the surfaces should be less than 0.003mm

STEP 4- FINAL TRIM AND JOINING

Final Product

STEP 5 - DRAFT ANALYSIS

• The produced part needs to have its display frame's material mode updated.
• The axis system is then panned along the direction of the part and positioned parallel to the tooling direction by enabling compass definition.
• Applying Lock Direction fixes the compass, and then snapping at any position on the component creates the mode dialogue box.
• Classification of the Color Codes and application of the Draft Angle.
• The study is then saved after using the Running point analysis to hover about the part and examine the permitted draft angles.
