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

AIM- Create the Screw boss for the Drill Handle considering the design rules mentioned.

OBJECTIVE-

• Sketches
• Use Positioned sketch
• Sketches should be Iso-Constrained
• Tree Structure
• Ensure Proper Tree Structure
• Geometrical sets should have a proper name based on the sketches present inside of it
• All the sketches should be created under the Geometrical set
• Report
• A detailed report should be done explaining the draft analysis and the tooling axis creation.
• An explanation should be given on the way of creating the tooling axis, particularly the Bisecting method.
• Reference
  • Refer to the below-given image to understand the position of the Screw Boss and Ribs

PROCEDURE-

CREATION OF TOOLING AXIS-

• TOOLING AXIS IS CREATED USING THE CG POINT OF THE CLASS A SURFACE.
• A LINE IS DRAWN THROUGH THE CG POINT IN THE Y DIRECTION OPF THE SURFACE.
• THUS THE MAIN TOOLING AXIS IS CREATED.

DRAFT ANALYSIS OF THE CLASS A SURFACE-

• DRAFT ANALYSIS IS DONE TO ENSURE THAT THE PRODUCT CAN EASILY UINDERGO THE MANUFACTURING PROCESS
• IT HELPS IN UNDERSTANDING THE PRODUCTION POSSIBILITY OF THE PODUCT.

CLASS B CREATION-

• CLASS B IS THE INWARD SURFACE OF THE GIVEN PRODUCT ITS CREATION IS DONE BY FOLLOWING WAYS.
• THE CLASS A SURFACE IS OFSETED AT 2.5MM INWARDS OF THE GIVEN SURFACE.
• THE OFFSET SURFACE HAS SOME PATCHES THAT NEEDS TO BE FIXED.
• USING THE MULTIPLE EXTRACT AND JOIN COMAND THE PATCH IS FIXED AND CLOSED SURFACE IS PRODUCED.
• THEN THE BOUNDARY OF THE SURFACE IS EXTRAPOLATED FOR 2MM TO FINALLY OBTAINED THE CLASS B SURFACE.

CLASS C CREATION-

• CLASS C SURFACE IS THE JOINING SURFACE BETWEEN THE CLASS A&B SURFACES.
• IT IS CREATED BY UYSING THE SWEEP TOOL ALONG THE BOUNDARY OF THE CLASS A SURFACE.
• THE BOUNDARY OF THE CLASS A SURFACE IS SWEEP WITH REFERENCE TO THE SURFACE AT 90' INWARDS DIRECTION.
• AND FINALLY ALL THE SWEEP SURFACES ARE TRIMMED TOGETHER TO ACHIVE THE CLASS C SURFACE.

FINAL SOLID SURFACE-

• ONCE ALL THE THREE SURFACES ARE TRIMED TOGETHER THE DESIRED THICKNESS OF 2.5MM IS OBSERVED .
• THEN USING THE CLOSED SOLID COMAND THE DESIRED PRODUCT IS FINALLY OBTAINED .

RIBS & SCREW BOSS-

RIBS-

• RIBS ARE AN ESSENTIAL B SURFACE FEATURES WHICH HELPS US TO INCREASE THE THICKNESS AND RESISTANCE OF THE PRODUCT WITHOUT HARMING THE PRODUCTION.
• TO CREATE THE RIBS A FLAT SURFACE OF THE SURFACE IS EXTRACT AND A SKETCH IS DRWAN IN THE SURFACE.
• THEN THE LINE IS EXTRUDE FOT THE HEIGHT OF 12.5MM .
• DRAFT OF .5MM IS GIVEN ON BOTHE SIDE OF THE RIB AND THUS THE RIB IS CREATED.

SCREW BOSS-

• SCREW BOSS IS THE FIXING FEATURE OF THE B SIDE SURFACE.
• IT IS CREATED BY USING THE SAME EXTRACT SUTFE AND BY DRAWING A SKETCH OF TWO CIRCLES .
• THEN THE CIRCLES ARE PADED FOR A HEIGHT OF 12.5MM AND THUS THE SCREW BOSS IS CREATED.
• THEN THE DRAFT OD .5MM IS GIVEN ON BOTH THE INNER AND OUTTER HOLES.
• FILLET IS ALSO GIVEN OF .25MM TO BOTHE THE RIBS AND SCREW BOSS.

TREE STRUCTURE-

CONCLUSION-

THE OBJECTIVE OF SUCCESSFULLY CREATING THE DRILL HANDLE IS ACHIVED ALONG WITH DRAFT ANLYSIS OF BOTHE THE CL;ASS A NAD FINAL SOLID SURFACE, ALSO RIBS AND SCREW BOSS ARE CREATED WITH RESPECT TO THE INDUSRTY STANDARDS.
