Week 9 - Attachment Feature Creation - Challenge 2

AIM - Create the Dog House for the Door Trim

CLASS A SURFACE

STEP 1 - Check the connectivity/continuity of the surface using the boundary tool or the close surface tool.

STEP 2 - TOOLING AXIS

• Check the best tooling direction by visualy considering the cost factor in mind. Here the best tooling direction is y direction because other two direction are problem making surafces.

STEP 3 - DRAFT ANALYSIS OF CLASS A

• Here the given class A surface is subjected to the daft analysis with draft angle 3 degree.
• From insert the draft analysis tool is taken, here we placing the compass to the tooling axis.
• Click on the class A, then we get a green colour on top and blue in the bottom. It means that draft angle decreasing from 3 degree to 0 degree.
• But some areas isnot cleared using the draft angle it shows the blue colour.

STEP 4 -CLASS B SURFACE

• Creating B surface by offsetting the surfaces from class A ,then Untrim and Extrapolate.
• Offset the component to 2.5 mm

STEP 5 - CLASS C SURFACE

• Using the boundary and sweep command we got the Class C surface.
• Sweep command is use with the reference surface

STEP 6 - CLASS A +CLASS C

• Join the class A and class C

STEP 7 - DOOR TRIM

• Trim the joined part with class B surface we get the Door TRIM surface.

STEP 8 - DOG HOUSE CREATION

• Convert the Door Trim to the part using the Close surface tool in part workbench.
• B SIDE FEATURE CREATION
  
  • FOR B Side feature creation we need both Tooling axis and Side core axis.
  • The side core axis is created in the X direction.

SIDE CORE AXIS

• Using the design rule draw the sketch for dog house

DOG HOUSE 1 SKETCH

DOG HOUSE 2 SKETCH

• Using the commands like Sweep,Extract,Plane,offset,Extrapolate,Trim,Split etc.. ,we create the doghouses.
• Then the dog house draft analysis is done using the draft analysis tool. Here the analysis is cleared using the 5 degree draft angle.

• After the draft analysis the Dog House is assembled to the Door Trim part.

STEP 9 - DRAFT ANALYSIS OF ASSEMBLED PART

• The assembled part is analysed using the 3 degree draft angle.Here we seen that the dog house area is not cleared by the 3 degree draft analysis.

• Result of draft analysis with draft angle 0.5 degree.
