Week 8 - Challenge 2 - Base Bracket Design

Base bracket

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

Tools used:

• Line
• Point
• Boundary
• Join
• multiple extract
• bisecting line
• draft analysis
• intersect
• sweep
• close body surface

Procedure:

Creating tooling axis

• Open the given CAT part file.
• find the correct tooling axis where the material doesn’t interfere with the tooling axis and all the elements can be created.
• Intersect the yz plane concerning the class a surface.

• Hide the class A surface and create a point to point lines on the suspected drafts
• Create a bisecting line with the two lines and point to create a tooling axis.

• The tooling axis is created for the component

Publication

• The publication is done to the component to make it visible and navigate easily
• To publish the component go-to tools >publications and then select the tooling axis and the class A surface
• A separate tree structure is formed under the main part.

Draft analysis

• Before going to drat analysis go to customized view parameter >under mesh >check material and then click ok
• Now for draft analyses go to insert >analysis>feature draft analysis.
• Use the compass to define the draft direction
• In the colour, the scale changes the draft angle to 3degree.
• The component changes to green as an indication of the passing draft angle.
• Use a running point to check the angle on the component.

• The draft analysis is complete.

Creation of class B surface

• Extract the surfaces from the class using multiple extract and untrim them.

• Use extrapolate to make sure that all the untrims are properly intersected to trim and offset the surfaces to 2.5 mm to create the thickness.
• Trim the extra surfaces using the trim command.

• Insert them into a new geometrical set and name it with their respective part name
• Apply fillets to the model after creating the entire surface.
• If the fillets are outside the fillet value will be added to the thickness of the component, for instance, the thickness of the component Is 2.5mm the fillet value is 3mm so the outside portion value should be 5.5mm to get uniform thickness.

• Perform trims one at a time so that it will be clear to understand.

The creation of the class c surface

• extracts the boundary from the class A surface using boundary.

• Using disassemble tool to divide the boundary as the boundary contains domains.
• Use sweep command >choose profile type line>subtype as with draft direction>choose guide curve and draft direction >give draft angle as 3 degrees>preview.

• After getting the sweep, join class A and C surfaces then trim the output with the class B surface to get the final output.

• Now open part design workbench and using close body surface create a solid of the component.
