Week 8 - Challenge 2 - Switch Bezel Design

AIM: The objective of the project is to create the Switch Bezel Plastic component through the given Class-A surface and the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end need to perform the Draft analysis on the model.

STEP 1

CREATING CLASS A SURFACE

• The below image is the given Class A Surface.

• Check the connectivity of the given Class A Surface by using JOIN or BOUNARY features & ensure that there is no dis-connectivity between any lines.

• Class A Surface After using Join feature.

STEP 2

CREATING TOOLING AIXS

• For creating tooling axis, first create a point on the Class A surface.
• Then, create a line on the surface using line feature with reference to that point and the Z- direction.

STEP 3

PERFORMING DRAFT ANALYSIS ON CLASS A SURFACE

• After checking the connectivity on class A surface, perform Draft Analysis on it.

STEP 4

CREATING CLASS B SURFACE

• To create Class B surface, offset the Class A Surface by using OFFSET feature.
• Give the offset value of about 2.5mm to the reverse direction of Class A Surface.
• After doing offset, check the offseted surface if there is any extra projected surfaces.
• If so, then perform EXTRAPOLATE on the extended surface and trim the unwanted projections using TRIM feature.

• Final Class B Surface after using extrapolate.

STEP 5

CREATING CLASS C SURFACE

• To create Class C Surface first create a boundary on Class A Surface by using Boundary feature.
• After creating a boundary, check whether its smooth or not. If not, use Curve Smooth feature to make the boundary smooth.
• Then, use Sweep on the boundary created with an draft angle of 3 degree.

• After creating surface C by using Sweep, trim the Class A Surface with the Sweeped surface.

• After triming both surface, again use Trim feature to trim with the Class B Surface to get the closed surface.

STEP 6

PERFORMING DRAFT ANALYSIS ON CLOSED SURFACE

• For doing Draft analysis the closed surfac, the surface should on Shading with Material.
• Ckeck the compass to align with the tooling axis direction.
• If, it becomes red adjust the compass accordingly to get the positive draft.

STEP 7

CREATING A PARTING LINE

• The parting line is used to showcase the boundary or area where the core and cavity seperates when pulling out.
• Use Multiple Extract Freture to define the boundaries from the Closed Surface.
• After extracting, change the line style to differentiate the parting line.
• The yellow dotted line represents the parting line.

• Multi view

• Solid Closed Surface
