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

AIM - Create the rib for the Drill Handle.

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.
• By intersecting the two lines we got the tooling axis.

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.

STEP 4 -CLASS B SURFACE

• Creating B surface by extracting the surfaces from class A ,then Untrim and Extrapolate.
• Thickness of the component to be 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 - COIN HOLDER

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

STEP 8 - RIB & SCREW BOSS CREATION

• Convert the Drill Handle surface to the part using the Close surface tool in part workbench.

• Using sketch and create the rib and screw boss.

• Design the rib and screw boss by following rules
• DESIGN RULES FOR SCREW BOSS

STEP 9 - DRAFT ANALYSIS OF PART

• The procedure is same as the class A analysis.
• But the draft angle is 3 is not clearing so we chamge the draft angle to 0.5.
• Here the some area is not cleared using the 0.5 degree draft.
