Week 9 - Attachment Feature Creation - Challenge 2

AIM:

To Create the Dog House for the Door Trim considering the design rules mentioned in the video. Consider the thickness of the part to be 2.5 mm.

"C" is where the doghouse contacts the backside of the surface

• Doghouse wall thickness at the intersection of the part wall ( C ) should be 40% or less than the main wall stock ( T ).

• The height of ( B ) should be between 3.0 – 6.0 mm

OBJECTIVE:

• 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

SOFTWARE USED : CATIA

Let us look at how we have designed

INPUT:

CAD DATA is downloaded and Opened with CATIA.

TOOLING AXIS:

Tooling axis is defined as such all the features of the part can be manufactured easily. so here we followed the below steps to create the tooling axis.

• Extract the side base and Create a point in the middle of the surface.
• line is with point and direction
• Hence we get the Tooling Axis

NOTE: Mentor Aditya Advised me to avoid bisecting method and use the above method to create tooling axis

DRAFT ANALYSIS:

• Draft is done on the Class A surface.
• Change it to material in customise view.
• Click the Draft analysis tool and click the surface and align the compass to tooling axis.
• So here is photo of not cleared (Green) draft.
• Refering with a group session. The mentor aditya said that it is Class A problem.
• So kindly consider.

B SURFACE:

• B surface is created by using the given Class A surface.
• Apart complicated face join other faces.
• Offset it to 2.5mm beneath the Class A.
• Create boundry and Create MSS, Extrapolate for the rest of the sections.
• Join the faces.
• Hence we have created the B surface.

C SURFACE:

• The outer edge of the Class A surface is taken as reference boundry.
• Sweep is made with reference to tooling axis with draft.
• Join the sections and create the C Surface

FINAL TRIM:

• Join A and C surface
• Trim with the B surface

• Closed Body is created

DOG HOUSE:

• Extract is taken and point is drawn.
• We then sketch the outer section on the extract and we Sweep
• Close the section and Thicken
• Create a trim following the rules and split it with the thicken body
• give drafts with core tooling axis and fillets

DRAFT ANALYSIS:

• Draft is done on the Dog House, closed body.
• Change it to material in customise view.
• Click the Draft analysis tool and click the surface and align the compass to tooling axis.
• So here is photo of not cleared (Green) draft.
• Refering with a group session. The mentor said that it is Class A problem.
• So kindly consider.

Here are few photos of the part
