Week 9 - Attachment Feature Creation (Ribs & Screw Boss) - Challenge 1
AIM: TO CREATE RIB AND SCREW BOSS ON GIVEN COMPONENT
GIVEN CLASS A SURFACE
DESIGN RULES FOR RIB CREATION
DESIGN RULES FOR SCREW BOSS CREATION
GIVEN IN THE CHALLENGE
General Guidelines for Bosses:
- Draft - 0.5 degrees on the walls of boss
- Thickness - Typically 40%* of the nominal wall at the base.
- Height to Diameter Ratio - 3:1
- Radii - 0.25mm maximum radii
LOCATION OF RIBS AND SCREWBOSS
CREATION OF TOOLING AXIS
- USING MEASURE INERTIA OPTION
- CLICK THE CLASS A SURFACE AND CREATE ASSOCTIAVTE GEOMETRY
- A INERTIA POINT IS CREATED
- USING THE POINT AS REFERNCE CREATE A LINE USING Y DIRECTION
- ONCE THE LINE IS CREATED ITS IS TAKEN FOR DRAFT ANALYSIS
- DRAFT ANALYSIS OF CLASS A COMPONENT
- CHANGE THE VIEW MODE TO MATERIAL
- USING DRAFT ANALYSIS COMMAND
- CLICK THE COMPASS AND PLACE IT OVER THE TOOLING AXIS
- AND CLICK ON THE SURFACE
- WE CAN SEE SOME FACE ARE NOT DRAFTED PROPERLY
CLASS B SURFACE CREATION
- CLASS B SURFACE IS CREATED USING EXTRACT
- OFFSET
- MULTISECTION
- AND JOIN COMMANDS
- OFFSET THE CLASS A SURFACE TO 2.5MM
- WE CAN FIND SOME MISSING PATCHES
- USING MULTISECTION COMMAND THE PATCHES ARE SLOVED
- AND IT IS JOINED WITH THE OFFSET AND CLASS B SURFACE IS CREATED
CLASS C SURFACE CREATON
- ONCE THE CLASS B IS DONE WITH HELP OF
- BOUNDARY
- SWEEP
- EXTRAPOLTE
- AND TRIM COMMANDS THE CLASS C SURFACE IS CREATED
- SURFACE WHICH ARE PERPENDICULAR TO THE TOOLING AXIS SWEEP COMMAND IS USED WITH REFERENCE SURFACE WITH 90 DEGREE
- FOR PARALLEL TO TOOLING AXIS SWEEP IS CREATED WITH DRAFT DIRECTION WITH 3 DEGREE
- USING EXTRAPOLATE INCRASE THE SIZE AND USING TRIM OPTION THE DESIRED CLASS C IS CREATED
- ONCE IT IS DONE IT IS JOINED WITH CLASS A
- AND USING CLASS A+C IT IS JOINED WITH CLASS B
AND MOVING TO PART DESIGN USING THICKNEN COMMAND THE FINAL BODY IS CREATED
CREATION OF RIBS
CREATION OF SCREW BOSS
FINALLY THE DRAFT ANALYSIS IS DONE FOR THE FINAL COMPONENT
