Week 9 - Attachment Feature Creation - Challenge 1
ATTACHMENT FEATURE (RIB)-
AIM-
TO CREATE THE RIB ON THE B-SURFACE OF THE COIN HOLDER AS PER THE DESIGN RULES AND ALSO PROVIDE THE DRAFT ANALYSIS FOR THE PART.
PROCEDURE-
SINCE WE HAVE ALREADY CREATED THE COIN HOLDER , WE JUST LOAD THE .catpart AND WORK ON THE B SURFACE .
RIB-
RIBS ARE THE ATTACHMENT FEATURE THAT GIVE STRENGTH TO THE COMPONENT AND ARE ATTACHED TO THE B-SURFACE.
THE RIB HAS TO BE CREATED ON THE B-SURAFCE OF THE COIN HOLDER. SINCE, IN THIS CASE THE RIB WE WANT IS JUST ALINE, SO WE CREATE A POSITIONING SKETCH ON THE OTHER SIDE OF THE B-SURFACE. BEFORE CREATTING, EXTRACT THE BOTTOM MOST FACE OF THE COIN HOLDER.
THE LINE IS THEN EXTRUDED ALONG THE TOOLING AXIS FOR AN EXTENT AS REQUIRED.
THE RIB DESIGN RULES STATES THAT THE HEIGHT OF THE RIB SHOULD BE 5 OR LESS TIMES THE WALL THICKNESS (5T).
NOW, PROVIDE THE THICKNESS TO THE EXTRUDE FOR ABOUT 0.4 TIMES THE WALL THICKNESS(PLACE THEM IN THEIR PROPER PARTBODY).
GIVE THE DRAFT TO THE BOTH FACES OF THE OF THE RIB OF 0.5DEGREES IN THE TOOLING AXIS DIRECTION WHOSE NEUTRAL FACE IS THE EXTRACT WE CREATED FIRST. CHECK WHETHER THE TIP OF THE RIB IS OF 0.75MM OR NOT.
GIVE THE FILLET TO THE RIB ON ALL FACES WHOSE RADIUS IS 0.25mm.
NOW CREATE ANOTHER RIB OF SAME FEATURES WHILE THE DISTANCE BETWEEN THEM SHOULD BE OF THE PROPER RATIO(3:1 OR 2:1 WHILE BOTH ARE ACCEPTABLE). IN THIS CASE THE SPACING IS GIVEN USING 3:1 RATIO (SPACING= HEIGHT/ WIDTH), TE SPACE GIVEN BETWEEN THE RIBS IS 5mm.
ASSEMBLES THESE BOTH RIBS TO THE MAIN PART BODY
DRAFT ANALYISIS IS ALSO TO BE PROVIDED FOR THE BODY ALONG THE TOOLING AXIS.
RESULT-
THE RIBS HAVE BEEN CREATED AND ASSEMBLED TO THE MAIN PART AS PER THE DESIGN RULES AND THE DRAFY ANALYSIS HAS ALSO BEEN CRAETED.
TOOLING AXIS-
IT IS THE DIRECTION FOR WHICH TOOLING IS MADE OR THE AXIS IN WHICH THE MOULD OR CAVITY MOVES.
THE TOOLING AXIS HAS BEEN CREATED FROM THE YZ-PLANE BY INTERSECTION METHOD WITH THE CLASS-A SURFACE OF THE PART. SINCE THE WALLS OF THE PART ARE PARALLEL TO EACH OTHER THE TOOLING AXIS WILL BE JUST PARALLES AS THE OTHER ONES.
