Week 10 - Challenge 3 - Door Trim Lower with Engineering Features
DOOR TRIM LOWER WITH ENGINEERING FEATURES:
INPUT GIVEN:
- CLASS A (STYLING DATA)
- THICKNESS VALUE
- LOCATION FOR HEAT STAKE
REQUIRED OUTPUT:
- SOLID PART(CLOSED SURFACE METHOD).
- ENGINEERING FEATURES AS SHOWN IN THE BELOW REFERENCE (HEAT STAKE, 2-WAY LOCATOR, 4-WAY LOCATOR).
- DRAFT ANALYSIS (CLASS A, FINAL COMPONENT).
CLASS A SURFACE:
THE GIVEN CLASS A SURFACE (STYLING DATA) IS GOOD THERE ARE NO GAPS BETWEEN SURFACES.
TOOLING AXIS:
THE GIVEN INPUT IS VISUALLY INSPECTED IN ALL THE AXES (X, Y, Z).
X-AXIS:
Z-AXIS:
Y-AXIS:
IN THE Y-AXIS ONLY ALMOST ALL SURFACES ARE VISIBLE.
CREATED A TOOLING AXIS IN Y.
CLASS A DRAFT ANALYSIS:
DRAFT ANALYSIS FOR 3-DEGREE HAS BEEN DONE FOR INPUT.
IT CLEARES THE 3-DEGREE DRAFT ANALYSIS IN THE TOOLING DIRECTION.
CLASS B SURFACE:
TO GET CLASS B SURFACE INPUT (CLASS A) IS OFFSETED FOR 3mm.
BECAUSE OF SMALLER RADII VALUE AND COMPLEX CURVATURE SOME FILLET SURFACES ARE MISSING IN THE OFFSETED SURFACES.
THOSE AREAS NEED TO BE WORKED LOCALLY.
PATCHING:
EXCEPT FOR THE OUTLINE, THE GREEN LINE INDICATE THE GAP BETEEN SURFACES.
EVERY AREA PATCH HAVE A SEPARATE GEOMENTRIC SET.
THIS HELPS IN CLEAN FEATURE TREE.
ALL PATCHES ARE WORKED.
THE BOUNDARY OF THE CLASS B SURFACE IS EXTRAPOLATED FOR FINAL TRIMMING.
TO VISUALLY INSPECT INTERSECTION CURVE IS CREATED FOR CLASS A & B.
THE CLASS B IS CREATED AND INSPECTED BY TAKING INTERSECTION CURVES.
CLASS C SURFACE:
BOUNDARY OF CLASS A SURFACE IS EXTRACTED.
OUTLINE CLASS C IS CREATED USING BOUNDARY AND TOOLING AXIS.
CLOSING SURFACE FOR OPENING IN MAP POCKET AREA CREATED SEPARATELY.
CLASS A+C:
CLASS A AND C SURFACES ARE JOINED.
CLASS A+B+C:
CLASS A+C IS TRIMMED WITH CLASS B SURFACE.
TO CREATE A SINGLE CLOSED PART.
PUBLICATIONS:
IMPORTANT LINE AND SURFACE ARE PUBLISHED FOR EASY WORKING.
SOLID BOBY:
USING CLOSED SURFACE COMMAND SOLID PART IS CREATED.
DRAFT ANALYSIS :
THE PART CLEARES 3-DEGREE DRAFT ANALYSIS.
ENGINEERING FEATURES:
ENGINEERING FEATURES ARE USED TO LOCATE, GUIDE, OR FIXATION BETWEEN THE MAIN PART AND SUB-PARTS.
IN THIS CAD EXERCISE WE NEED TO CREATE LOCATOR AND HEAT STAKES.
4 WAY LOCATOR:
USED TO LOCATE THE PART CORRECTLY WHILE ASSEMBLING TO COUNTERPART.
ALSO TO ARREST THE DEGREES OF FREEDOM.
2 WAY LOCATOR:
2 WAY LOCATOR ARE USED FOR THE SAME FUNCTION AS 4 WAY LOCATORS.
ONLY THE DEGREES OF FREEDOM ARRESTED ARE LESS COMPARED TO 4 WAY.
HEAT STAKE:
HEAT STAKES ARE USED TO WELD AND JOIN TWO PARTS.
IT IS PLASTIC WELDING PROCESS.
WITH THE GIVEN HEAT STAKE LOCATION INPUT.
CHOOSE ONE IN FLAT OR LESS CURVY FACE TO CREATE PARENT HEAT STAKE.
IN OTHER AREAS SOLIDS ARE COPIED PASTED AND TRANSLATED.
FEATURE TREE COLLAPSED:
HERE WE CAN SEE THE STRUCTURED FEATURE TREE AND THE FINAL PART WITH ENGINEERING FEATURES.
FEATURE TREE EXPANDED:
SNAP OF FINAL PART IN VARIOUS VIEWS:
CLEARED 0.49 DEGREE DRAFT ANALYSIS WITH ENGINEERING FEATURES.
DETAILED AREA FOR LOCATOR AND HEAT STAKE:
CONCLUSION:
IN THIS CHALLENGE WE HAVE CREATED THE SOLID PART USING THE CLOSED SURFACE METHOD.
ADD HEAT STAKE AND LOCATORS BY REFERRING TO THE REQUIRED SNAP.
PART CLEARED THE DRAFT ANALYSIS.
