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

DOOR HANDLE SURFACE CREATION AND THE RIB, SCREW BOSS COMMAND WITH DRAFT ANALYSIS

STEP 1: CREATE A TOOLING AXIS.

STEP 2: CREATE B SURFACE USING OFFSET OS CLASS A.

STEP 3: CREATE A C SURFACE USING THE BOUNDARY AND SWEEP COMMANDS.

STEP 4: JOIN THE C SURFACE AND CLASS A AND THEN TRIMS WITH B SURFACE.

STEP 5: CLOSE SURFACE COMMAND TO CREATE THE FINAL PART BODY

STEP 6:CREATE THE RIB AND SCREW BOSS AND DRAFT IT WITH 0.5 DEG AND FILLET IT.

STEP 7: DRAFT ANALYSIS.

TOOLING AXIS

THE TOOLING AXIS IS CREATED BY USING THE METHOD OF BISECTING THE TWO LINES

CLASS A

THE CLASS A SURFACE IS GIVEN.

B SURFACE

IN B SURFACE OFFSET THE CLASS A SURFACE AND SOME ERRORS ARE SHOWN IN B SURFACE AND THEN CLEAR THE ERRORS IN B SURFACE AND THE ERRORS ARE CLEARED BY USING THE BLEND COMMAND AND FILL COMMAND.

THE OFFSET DISTANCE IS 2.5mm

C SURFACE

THE C SURFACE IS CREATED BY USING THE BOUNDARIES AND SWEEP METHOD.

IT IS CREATED TO CLOSE THE A & B SURFACE

FINAL PART WITH THE RIB AND SCREW BOSS

THE CLASS A SURFACE JOINS C SURFACE AND TRIMS WITH B SURFACE AND GETS THE FINAL PART BODY USING THE CLOSE SURFACE COMMAND.

RIBS AND SCREW BOSS

RIBS ARE ADDED TO ADD STRENGTH TO THE PART BODY.

RIBS AND THE SCREW BOSS AS A DRAFT ANGLE OF 0.5 DEG.

THEN SCREW BOSS IS USED TO FIX THE BODY IN THE DOOR PANEL.

DRAFT ANALYSIS

THE DRAFT ANGLE FOR THE SURFACE IS 3 DEG
