Week 9 - Attachment Feature Creation - Challenge 2

AIM:

• To Create theDoor Trim Component from the given Class-A surface.
• To Create the Tooling axis for the given Class-A Surface meeting the requirements of the draft angle.
• To perform the Draft analysis on the model.
• To Create the B Side Feature in the component by following the design rules.

OBJECTIVES:

• Sketches
• Use Positioned sketch
• Sketches should be Iso-Constrained
• Tree Structure
• Ensure Proper Tree Structure
• Geometrical sets should have a proper name based on the sketches present inside of it
• All the sketches should be created under the Geometrical set
• Report
• A detailed report should be done explaining the draft analysis and the tooling axis creation.
• An explanation should be given on the way of creating the tooling axis, particularly the Bisecting method
• Reference
  • Refer to the below-given image to understand the positions of the Dog House
  • Submission in challenge box
    • Screenshots of the completed design in various orientations (Isometric, Front, Side, and Top View)
    • Refer to the below-given image to understand the positions of the Dog House

DESCRIPTION:

• Sketches

• Tree Structure

• Report
• A detailed report should be done explaining the draft analysis and the tooling axis creation.
• An explanation should be given on the way of creating the tooling axis, particularly the Bisecting method

Creating tooling axis -

The Tooling Direction is basically the direction that the mold pulls a part. The mold is built in two separate pieces, basically. You have a Cavity side and you have the Core side. The Core pulls apart from the Cavity and that's the Dye line or the Tooling Direction.

• Open the given CAT part file.
• Check for gaps between surfaces for that click on join and then preview.
• If theres any gap between the surfaces join them with a maximum tolerance of 0.003 mm.
• Extract the boundary and dissemble the boundary.
• Find the correct tooling axis where the material don't interfere with the tooling axis and all the elements can be created.

• Intersect the yz plane with respect to the class A surface.
• Hide the class A surface and create point to point lines on the suspected drafts.
• Create bisecting line with the two lines and point to create a tooling axis.
• Bisecting lines were used to get the exact medium from the two sides so that maximum positive draft angle can be achieved.

Draft Analysis

The Draft Analysis command enables you to detect if the part you drafted will be easily removed. This type of analysis is performed based on color ranges identifying zones on the analyzed element where the deviation from the draft direction at any point, corresponds to specified values.

• 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 compasss to define the draft direction.
• In the colour scale change the draft angle to 3 degree.
• The component changes to green in indication of passing draft angle.
• Use running point to check the angle on the component.

CREATING CLASS B SURFACE

• Extract the surfaces from the class A 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 trim command.
• Insert them into new geometrical set and name it with respective part names.
• Apply fillets to the model after creating the entire surface.
• If the edges are outside the fillet value will be added to the thickness of the component and if the edges are inside, the fillet value will be subtracted from the thickness of the component, for instance the thickness of the component Is 2.5mm the fillet value is 15mm so the outside portion value should be 17.5mm and inner eges should be filleted 12.5mm to get uniform thickness.
• Perform trims one at a time so that it will be clear to understand.

5. CREATING CLASS C SURFACE

• Extract the boundary from the class A surface using boundary command.
• 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 > draft angle as 3 degree > preview.
• After getting sweep then trim the output with class B surface to get final output.

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