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

REPORT ON DESIGNING RIBS AND SCREW BOSS FOR AN DRILL HANDLE

THE STEPS FOR DESIGNING ARE AS FOLLOWS:-

1.INPUTS:-

HERE WE WILL GET CLASS A SURFACE AS AN INPUT TO CREATE THE FINAL COMPONENT WHICH IS AS SHOWN IN BELOW IMAGE.

2.TOOLING AXIS CREATION:-

TO CREATE AN TOOLING AXIS WE HAVE TO CHECK WHEATHER ALL THE SURFACES OF AN CLASS A SURFACE IS VISIBLE ALONG ANY PARTICULAR AXIS OR NOT.
AS MOST OF THE SURFACES ARE VISIBLE ALONG Y AXIS AND SOME OF THE SURFACE ARE NOT VISIBLE AND CANNOT BE CLEARED, SO LETS CREATE A TOOLING AXIS USING BISECTING METHOD.
INITIALLY WE HAVE TO EXTRACT THE SURFACE, CREATE A POINT AND USING THE INTERSECT 3D ELEMENT TO GET THE OUTLINE OF THE SURFACES TO CREATE A LINE AND BISECTING THE LINE TO OBTAIN THE DUMMY TOOLING AXIS AS SHOWN IN BELOW IMAGE.

3.DRAFT ANALYSIS ON A CLASS A SURFACE:-

DRAFT ANALYSIS IS USED TO CHECK WHEATHER THE SURFACES CAN BE CLEARED WITH RESPECT TO THE DUMMY TOOLING AXIS OR NOT.
ON SELECTING THE DRAFT ANALYSIS TOOL WE PLACE A COMPASS ON THE DUMMY TOOLING AXIS AND LOCK IT. BY SELECTING THE CLASS A SURFACES THE DRAFT ANALYSIS IS OBSERVED IN THE FORM OF COLOUR CODES AND THE DRAFT ANALYSIS ON THE OTHERSIDE CAN BE CHECKED BY INVERSE DRAFT ANGLE TOOL.
AS SOME OF THE SURFACES ARE 1 DEGREE DRAFT ALONG THE TOOLING AXIS, TO INCREASE THE DRAFT ANGLE THESE MODIFICATIONS ARE TO BE MADE IN CLASS A SURFACES BY USING ALIAS SOFTWARE.
HERE THE DUMMY TOOLING AXIS CAN BE TERMED AS MAIN TOOLING AXIS.

4.CLASS B SURFACE CREATION:-

TO CREATE A CLASS B SURFACE OFFSET THE CLASS A SURFACE TO 3MM, DURING OFFSETTING SOME OF THE FILLETS WERE MISSING AND BY CREATING THE MISSING FILLET THE CLASS B SURFACES CAN BE CREATED.
FILLET VALUE DETERMINATION GEOMETRICAL SET IS CREATED TO OBTAIN THE EDGE FILLET VALUES FROM THE CLASS A SURFACE TO CREATE THE FILLETS ON THE CLASS B SURFACES.

5.CLASS C SURFACE CREATION:-

TO CREATE AN CLASS C SURFACE FIRST WE HAVE TO CREATE AN BOUNDARY ON A CLASS A SURFACE THEN USING SWEEP COMMAND CREATE THE SURFACE WHICH IS 3 DEGREE DRAFT WHICH IS PARALLEL TO THE TOOLING AXIS OR 90 DEGREE DRAFT WHICH IS PERPENDICULAR TO THE TOOLING AXIS WHICH IS AS SHOWN IN THE BELOW FIGURE.

6.CLASS C AND CLASS A SURFACE JOIN:-

HERE WE HAVE TO JOIN CLASS A AND CLASS C SURFACES WHICH ARE AS SHOWN IN BELOW FIGURE.

7.FINAL TRIM:-

HERE WE HAVE TO TRIM THE JOIN OF CLASS A AND CLASS C SURFACES WITH THE CLASS B SURFACES WHICH ARE AS SHOWN IN BELOW FIGURE.

8.CLOSE SURFACE CREATION:-

TO CREATE AN CLOSE SURFACE SWITCH TO THE PART WORKBENCH AND CONVERT THE SURFACED MODEL INTO THE SOLID MODEL WHICHIS AS SHOWN IN BELOW IMAGE.

9.RIBS CREATION:-

RIBS ARE CREATED AS PER THE IMAGES GIVEN IN THE CHALLENGES.
FIRSTLY WE HAVE TO CREATE THE GEOMETRICAL SKETCH WHERE WE HAVE TO DRAW A SKETCH AND EXTRUDE THE LINE IN SURFACE WORKBENCH TO GET A PLANE, THEN IN PART WORKBENCH THICKEN THE PLANE TO REQUIRED THICKNESS WHICH ARE SHOWN IN BELOW IMAGES.

10.SCREW BOSS CREATION:-

THEN BY USING REMOVE COMMAND THE HOLE OF 5.2 DIA IS REMOVED FROM SCREW BOSS AND ADDED TO THE DRILL HANDLE.
A DRAFT OF 0.5 DEGREES IS GIVEN ON BOTH INNER AND OUTER SURFACES OF THE SCREW BOSS WHICH ARE AS SHOWN IN BELOW IMAGES.

11.DRAFT ANALYSIS ON FINAL COMPONENT:-

HERE DRAFT ANALYSIS IS DONE ON A FINAL COMPONENT WHICH ARE AS SHOWN IN THE BELOW IMAGES.

12.ORIENTATION VIEWS:-

13.PUBLICATIONS:-

HERE TOOLING AXIS, CLASS A, CLASS B AND CLASS C SURFACES ARE PUBLISHED WHICH CAN BE RETRIVED EASILY AS SHOWN IN BELOW IMAGES.
