Week 11 - Final project
FINAL PROJECT - DOOR TRIM DESIGN WITH ALL ENGINEERING FEATURES.
- IN THIS CHALLENGE WE HAVE BEEN GIVEN WITH CLASS A SURFACE FOR DOOR TRIM WITH MASTER SECTION FOR ATTACHMENT OR B SIDE FEATURES.
- AS WE SEE IN THE ABOVE IMAGE.
- THERE ARE TOTAL 4 PARTS IN THIS DOOR TRIM
1. DOOR ARM REST
2. DOOR LOWER SUBTRACT
3. MAP POCKET
4. BOTTLE HOLDER
- FIRST I HAVE CREATED TOOLING AXIS FOR INDIVIDUAL CLASS A SURFACE AND PERFORM DRAFT ANALYSIS ON IT.
- BEFORE WE HAVE TO CREATE CLOSE SURFACE FOR ALL THE PARTS.
- FOR THAT I OPENED THIS CAT PART IN ASSEMBLY WORKBECH AND ADDED 4 NEW PARTS TO IT AND COPY PASTED EACH CLASS A SURFACE WITH THERE MASTER SECTIONS.
- AFTER THIS I CREATED CLOSE FOR ALL THE PARTS , BY FOLLOWING RESPECTIVE METHODS OF CLASS B AND CLASS C CREATION.
- SO NOW WE HAVE ALL CLOSE SURFACE TOGETHER AS WE OUR WORKING ON ASSEMBLY WORKBENCH.
- AFTER THIS WE HAVE TO CREATE B SIDE FEATURES FOR ATTACHMENT , HERE THE DOOR LOWER SUBTRACT IS MAIN PART BECAUSE EVERY OTHER PARTS WILL BE ASSEMBLED TO IT.
- I STARTED WITH DOOR ARM REST.
- THIS IS THE MASTER SECTION GIVEN FOR THE DOOR ARM REST , FROM THIS WE HAVE TO CREATE A FLANGE
- WE CAN SEE THREE LINES HERE , THE 1ST LINE IS REFERANCE OF THE CUSION WHICH WE DONT HAVE TO CONSIDER.
- 2ND AND 3RD LINE IS THICKNESS OF FLANGE , FROM THESE I EXTRACTED THE LINE AND CREATED CLASS A , CLASS B AND CLASS C SURFACE FOR THE FLANGE.
- AFTER THAT MAKE IT AS CLOSE SURFACE.
- YOU CAN SEE IN THE ABOVE IMAGE.
- ALSO WE NEED CLEARANCE THERE FOR THE HEAT STAKE , I MEASURE FROM THE MASTER SECTION DIAMETER OF HOLE WAS FOUND 8.5 MM.
- SO I CREATED 8.5 MM DIA CIRCLE PAD IT AND REMOVE IT FROM THE FLANGE USING BOOLEAN OPERATION.
- AFTER THIS I CREATED FLANGE FOR MAP POCKET.
- THIS IS THE GIVEN MASTER SECTION FOR FLANGE IN MAP POCKET , WE HAVE TWO FLANGES IN MAP POCKET.
- IN THE SAME WAY I EXTRACTED LINES AND USING MULTIPLE SWEEPS , EXTRUDE , OFFSET AND EXTRAPOLATE ETC COMMANDS
I CREATED FLANGE ON MAP POCKET SAME WAY AS I DID IN ARM REST.
- IN THE SAME WAY WE NEED CLEARANCE FOR HEAT STAKE.
- THAN I CREATED FLANGES FOR BOTTLE HOLDER.
- FOR BOTTLE HOLDER WE DIDNT HAVE ANY MASTER SECTION.
- SO I CREATED A FLANGE LIKE THIS , WITH SOME APPROPRIATE DIMENSIONS ALSO ENSURE THAT SKETCH BY ISO - CONTRAINED.
- THE FLANGE WAS GOOD LOOKING AND IT CAN USED.
- WE NEED 4-5 FLANGES IN BOTTLE HOLDER , SO I WAS USED SYMMETRY , TRANSALATION AND ROTATION COMMANDS AND COPY / PASTED
FLANGES AT DESIRED POSITION.
- YOU CAN SEE IN BELOW IMAGE.
- THE FLANGES HAVE SHARP EDGES , AND WE CANT HAVE SHARP EDGES SO I HAVE GIVEN FILLETS AT THE EDGES OF EVERY FLANGES.
- AFTER THIS I CREATED FEATURES ON THE LOWER SUBTRACT EVERY ATTACHMENT FEATURES ARE SITUATED IN DOOR LOWER SUBTRACT.
- FOR THE FLANGES ATTACH WE NEED HEAT STAKE SO I CREATED HEAT STAKE FROM THE MASTERS SECTION I FOUND DIAMETER FOR IT
AS 7.5 MM AND 4.5 MM DIA.
- I PAD THIS GIVEN NOMINAL DRAFT OF 0.5 MM FOR THE HEAT STAKE.
- AFTERWARDS I COPY PASTED THESE HEAT STAKE AT REQUIRED LOCATIONS WITH THE HELP OF REFERANCE POINTS OR CURVES.
WE CAN USE POINT TO POINT TRANSLATION OR DISTANCE TO DIRECTION.
- YOU CAN SEE ON ABOVE IMAGE.
- AND WE NEED RIBS TO SUPPORT THE HEAT STAKE TO AVOID BREAKAGE OR FAILURE.
- I CREATED RIBS OF 12 BY 12 MM OF 1 MM THICKNESS.
- ALSO WE NEED TO DRAFT TO RIBS , GIVEN DRAFT OF 0.5 DEG TO ALL FACES OF RIBS.
- AND AS PER DESIGN RULES THE GAP BETWEEN HEAT STAKE AND ITS CLEARANCE MUST BE 0.5 MM , I HAVE ENSURE THAT I HAVE TAKEN MEASUREMENT AND FOUND GAP TO BE 0.45 MM APPROX AT EVERY AREA.
- NOW ALL THE FLANGES AND HEAT STAKES ARE CREATED WITH RIBS AND THEY ARE FOLLOWING THE DESIGN RULES.
- AFTER THIS WE ALSO NEED TO HAVE DOG HOUSE AT THE DOOR LOWER SUBTRACT TO AVOID SINK MARKS ON THE SURFACE.
- TO DESIGN A DOG HOUSE FIRSTLY I TAKEN A POINT ON THE SURFACE WITH THAT CREATED A PLANE.
- AND INSERTED A SKETCH THERE , I DRAWN A RECTANGLE OF 24 BY 24 MM WE NOW THE DOG HOUSE A OPENED FROM ONE SIDE SO MAKE ONE LINE AS CONTRUCTION ELEMENT.
- AFTER THAT I USED SWEEP COMMAND TO EXTRUDE IT FOR GIVING DRAFT TO IT.
- WE KNOW DOG HOUSE SHOULD HAVE DRAFT OF 1.5 DEG , SO I USED DRAFT DIRECTION SWEEP TYPE WITH HELP OF TOOLING AXIS.
- AND EXTRUDED IT FOR 40 MM.
- AFTER THIS GIVEN THICKESS TO THE DOG HOUSE OF 2 MM.
- NOW WE NEED THE C CUT SECTION IN THE DOG HOUSE AT HEIGHT OF 4 TO 6 MM.
- I USED SAME LINE OF THE RECTANGE AND CREATED A SURFACE OFSET IT FOR 5 MM.
- THAN USED SPLIT COMMAND FROM PART WORKBENCH TO SPLIT AND GOT THE CUT IN THE DOG HOUSE.
- YOU CAN THE PROCESS IN BELOW IMAGES.
- WE NEED CLEARANCE FOR THE PUSH CLIP AT TOP OF THE DOG HOUSE SO I DRAWN A CIRCLE OF 5 MM RAD.
- WE ALSO NEED SIDE CORE AXIS FOR DRAFT ANALYSIS ON DOG HOUSE SO FROM SAME POINT OF MAIN TOOLING AXIS I CREATED SIDE CORE AXIS.
- AND PERFORM DRAFT ANALYSIS ON DOG HOUSE AND IT WAS CLEARED.
- AT LAST WE HAVE PUSH CLIP WHICH WE HAVE TO ASSEMBLE AT TOP OF THE DOG.
- SO I COPY PASTE THE CAT PART OF PUSH CLIP IN ASSEM WORKBENCH.
- THAN I CREATED REFERANCE AXIS ON BOTH PUSH CLIP AND ON CLEARANCE OF DOG HOUSE , SO WITH HELP OF ASSEMBELY COMMAND FIRST I COINCIDENT BOTH OF THEM AND AFTER THAT SURFACE CONTACT.
- YOU CAN SEE IN ABOVE IMAGE.
- SAME WAY WE HAVE 3 DOG HOUSE SO GET 3 PUSH CLIPS AND ASSEMBLED THEM.
DRAFT ANALYSIS
- I HAVE PERFORM DRAFT ANALYSIS ON EACH PART
- FOR DOOR ARM ARE WERE FEW PATCH IN RED.
- ALSO IN BOLLTLE HOLDER FEW PATCHS ARE RED INVERSING IT SOLVES THE PROBLEM.
- IN MAP POCKET SOME CLASS C SURFACE IS NOT CLEARED.
- FOR THE DOOR LOWER SUBTRACT WITH MAIN TOOLING SURFACE WAS CLEARED.
- FOR DOG HOUSE AND OTHER FEATURES I GOT SIDE CORE AXIS AND IT WAS CLEARED WITH SIDE CORE AXIS.
