Week 10 - Challenge 1- Attachment Feature Creation (Ribs & Screw Boss)

WEEK 10 CHELLANGE 1 (ATTECHMENT FEATURE RIBS & SCREW BOSS)

CLASS A SURFACE DRAFT ANALYSIS:

• CREATED POINT IN CENTRE OF SURFACE
• USING SAME POINT CREATED CREATED DUMMY TOOLING AXIS
• PLACED NEW AXIS SYSTEM ON SURFACE ON POINT
• CREATED INTERSECTING SKETCH ON XY PLANE OF NEW AXIS SYSTEM
• USED SIDE WALL LINES TO CREATE BISECTING LINE ON SAME POINT.
• RESULTING LINE IS DEFINED AS FINAL TOOLING AXIS.

CLASS A DRAFT ANALYSIS:

• TAKE FINAL TOOLING AXIS TO PLACE COMPASS FOR DRAFT ANALYSIS
• SELECTED A SURFACE
• WHOLE SURFACE HIGHLITED WITH GREEN COLOR EXPECT 2 SIDE WALL WHICH IS HAVING 2 DEGREE OF DRAFT ANGLE.

SOLID MODEL CREATION:

• EXTRACTED CLASS A SURFACE AND OFFSETED FOR 3MM INSIDE
• CORRECTED NECESSARY SURFACES AND FILLETS USING EXTRACR, JOIN, UNTRIM, TRIM AND OTHER COMMANDS
• CREATED C SURFACE USING SWEEP WITH REFERENCE COMAND AT 90 DEGREE FOR SURFACES PARALLEL TO TOOLING AXIS
• USED SWEEP WITH DRAFT FOR SURFACE PERPENDICULAR TO TOOLING AXIS AT 3 DEGREE DRAFT
• AND TRIMMED THEN TOGETHER TO CREATE SINGLE C SURFACE
• JOINED C SURFACE WITH A SURFACE AND TRIMMED IT WITH B SURFACE
• CHECKED FOR CLOSSED BOUNDRY USING BOUNDRY COMMAND
• USED CLOSE SURFACE COMMAND FROM PART WORK BENCH TO SOLIDIFY THE SURFACE.

RIB FEATURE CREATION:

• CREATED POSITIONED SKETCH ON ZX PLANE OF AXIS SYSTEM
• DRAWN HORIZONTAL LINE AND FULLY DEFINED IT BY GIVING PROPER DIMENSIONS AND CONSTRAINS
• EXTRUDED IN DIRECTION OF TOOLING AXIS AS SURFACE FOR 15MM
• EXTRECTED B SURFACE SIDE OF BODY AND TRIMMED RIB SURFACE WITH IT
• EXTRAPOLATTED RIB SURFACE TO PROPERLY INTERSECT WITH PART BODY
• INSERTED NEW BODY AND THICKEN RIB SURFACE FOR 1.2 MM
• APPLIED 0.5 DEGREE DRAFT ON ALL SIDE WALL OF RIBS USING DRAFT COMMAND
• ASSEMBLED RIB 1 WITH DOOR HANDLE
• GIVEN RADIUS OF 0.25MM TO ALL EDGES OF RIB
• USING SAME STEPS CREATED RIB 2 AT SPECIFIC DISTANCE.

SCREW BOSS FEATURE CREATION:

• IN POSITIONED SKETCH OF ZX PLANE CREATED 2 CIRCLES
• EXTRUDED SKETCH AS SURFACE FOR 15 MM IN DIRECTION OF TOOLING AXIS
• USED PREVIOUSLY ECTRACTED B SIDE SURFACE AND OFFSETED FOR 1MM TOWARDS A SURFACE TO INTERSECT CIRCLE WITH DOOR HANDLE BODY
• EXTRACTED BOTH CIRCLE SURFACES SEPERATELY AND TRIMMED TWITH OFFSETED SURFACE
• USED COLSE BODY COMMAND TO CLOSE SCREW BOSS SURFACE
• SOLIDIFYED IT WITH CLOSE SURFACE COMMANT AS NEW BODY
• GIVEN DRAFT OF 0.5 DEGREE TO BOTH INSIDE AND OUTSIDE SURFACE SEPERATELY
• ASSEMBLED SCREW BOSS 1 WITH DOOR HANDLE
• GIVEN FILLET OF 0.25 MM TO ALL EDGES OF SCREW BOSS
• CREATED ANOTHER SCREW BOSS ON OTHER SIDE FOLLOWING SAME STEPS MENTIONED ABOVE.
