Week 9 - Challenge 2 - Switch Bezel Design

ANSWER

AIM

To perform draft analysis and make a solid model from the given class A input.

TOOLING AXIS CREATION

• Dispatch the CAT component file.
• Before to clicking join, inspect surfaces for gaps, and then click preview.
• select the proper tooling axis so that no material will interfere and all the elements can be produced.
• Using the surface at the bottom as a starting point, design an axis system.
• the class a surface walls and the yz plane must intersect.
• Make a line in the zx plane that is 6 degrees from the intersection.
• On the suspected drafts, cover the class A surface and draw point-to-point lines.
• The two lines should be bisected at that point to form a tooling axis.
• The component's tooling axis is generated.

DRAFT ANALYSIS

• Go to customised view parameter >under mesh >tick material before proceeding to drat analysis, and then press ok.
• Go to insert >analysis>feature draught analysis to access the draught analyses.
• Set the draught direction using the compass.
• Change the draught angle on the colour scale to 3 degrees.
• As a passing draught angle is shown, the component turns green.
• Check the component's angle using running points.
• The preliminary analysis is finished.

CREATION OF CLASS B SURFACE

• Using repeated extracts, remove the surfaces from the class and untrim them.
• To trim and offset the surfaces to 3 mm to generate thickness, use extrapolate to ensure that all of the untrims are appropriately intersected.
• Using the trim command, remove the superfluous surfaces.
• Add them to the new geometric set and give it the names of the corresponding parts.
• After finishing the model's full surface, add fillets.
• The fillet value will be added to the component's thickness if the fillets are outside. For example, if the component's thickness is 3 mm and the fillet value is 3 mm, the outside portion value should be 11 mm to achieve uniform thickness.
• Trims should be carried out one at a time for clarity.

CREATION OF CLASS C SURFACE

• Utilizing boundary, separate the boundary from the class A surface.
• Utilize the sweep command, select the profile type line, subtype with draught direction, guide curve, and draught direction, and then click Preview.
• To create a clean surface and reduce the spots, use a smooth curve.
• Become a part of the class A and class C surface.
• If there are any boundaries, check them, extrapolate the class A to 0.05 mm, and then trim the material with class C.
• After obtaining the sweep, trim the output with a class B surface to obtain the desired result.
• Now make a solid of the component using the open part design workbench and a close body surface.
• Conduct a draught analysis after getting close to the body surface. Some components of the company have a 2.9 degree draught; this draught needs to be modified, and for the maian wall, the tooling axis needs to be adjusted.
