Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1

Drill Handle

Inputs:

Class-A surface

General Guidelines for Ribs

General Guidelines for Bosses

Given Class-A surface.

Continuity check

To ensure the connectivity between the surfaces join command is used.

Later boundary command also used to ensure there is no open profile in the middle of the surfaces.

Tooling Axis:

Step 1:

a. Extracted base surface & a point is created at centre of the surface.

b. An axis system is created at the point.

Step 2:

a. Position sketch is made, in which given Class-A surface is intersected with YZ plane, and two lines were created along the incline profile.

b. There no 2nd side surface is available to create intersection between class-A & YZ plane.

Step 3: A bisecting line created using bisecting line 1 and line created in position sketch.

Draft analysis on Class-A surface

Few steps need to be followed to perform draft analysis.

Step 1: Go to View tab

View --> Customise view parameters --> Mesh --> Material --> Ok.

Step 2:

a.Go to Insert --> Analysis --> Feature Draft Analysis

b. Click on compass symbol, drag & drop compass on tooling axis. Ensure the position as shown in below image

c. Click on lock symbol, and click on the surface to see the results.

Draft Analysis on Final Trim.

Draft Analysis on solid body of Drill Handle.

Class-B surface creation

Class-A surface is off-set by thickness 2.5mm.

Off-set Class-A surafce.

Gap is filled using Fill command.

Class-B surface creation

Class-C surface is created using Sweep command.

Class-A&C surface.

Class-A&C surfaces joined together for Final Trim.

Final Trim

Class-A&C is trimmed with Class-B to get Final Trim.

All views of Solid Drill Handle body.

Rib Creation

Position sketch is made & lines were extruded. Extruded surfaces are trimmed using Class-B & extrapolated downward by 1mm.

Surfaces Thickened, drafted & raidus applied.

Ribs created as per given design guidlines.

Screw Boss Creation

Screw Bosses created as per given design guidlines.

Final Output.
