Week 8 - Challenge 4 - Bumper
Create the Bumper Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the draft angle requirements and performing the draft analysis on the model at the end.
Take the Thickness of the component to be 3 mm
Screenshots of the Draft analysis report for both the given Class-A surface and the final plastic component
DRAFT ANALYSIS
TAKE ONE LARGE SURFACE AMONG THE SURFACE OF THE BUMPER. AND TAKE A CENTER POINT OF THE PARTICULAR SURFACE. DRAW A LINE WITH REFERENCE TO THAT POINT ALONG X DIRECTION. AND THIS MAY BE YOUR TOOLING AXIS.
WITH THE HELP OF THIS TOOLING AXIS WE CAN PERFORM A DRAFT ANALYSIS. IF THE ANALYSIS GET SUCCESSES MEANS THE ENTIRE BUMPER WILL TURN INTO GREEN COLOUR
B SURFACE CREATION
AFTER SUCCESSFUL COMPLETION OF DRAFT ANALYSIS WE HAVE TO OFSET THE ENTIRE CLASS-A SURFACE FOR 3mm
THEN WE CAN NOTICE SOME PATCHES ON THE OFFSET SURFACE DUE TO THE IMPROPER OFFSET OF THE FILLET
HERE WE CAN NOTICE THREE DIFFERENT PATCHES
PATCH 1
PATCH 2
PATCH 3
NOW WE ARE GOING TO SOLVE THOSE PATCHES ONE BY ONE, EXTRACTING THE BESIDE SURFACE OF THE PATCH. AND REMOVE THE UNWANTED PORTION BY USING A JOIN COMMENT BY MEANS OF A SUB-ELEMENT TO REMOVE, AND EXTRAPOLATE THE EXTRACTED SURFACE TO THE ADJACENT SIDE. MAKE SURE BOTH ADJACENT SIDES INTERSECT WITH EACH OTHER. NOW TRIM THE UNWANTED PORTION TO GET A REQUIRED COMPLETED SURFACE.
REPEAT THE SAME STEPS FOR THE REMAINING TWO PATCHES AND GET THE OUTPUT LIKE BELOW
AFTER COMPLETION OF THE THREE PATCHES WE NEED TO CREATE A C-SURFACE WITH REFERENCE TO THE CLASS-A SURFACE
C-SURFACE CREATION
CREATING C-SURFACE MEANS WE NEED TO SWEEP FOR 90 deg TO THE CLASS-A SURFACE. AND GET AN INTERSECTION WITH THE EXTRAPOLATED B-SURFACE TO GET A COMPLETELY CLOSED SURFACE.
SWEEP THE BOUNDARY OF CLASS-A SURFACE ONE BY ONE LIKE BELOW
MADE INTERSECT WITH THE EXTRAPOLATED CLASS-B AND TRIM TOGETHER TO GET A FINAL COMPLETED CLOSED SURFACE AS BELOW
AFTER GETTING THE FINAL COMPLETE CLOSED SURFACE ENTER IT INTO THE PART WORKBENCH
MAKE THE CLOSE SURFACE INTO SOLID THEN YOUR MODEL WILL LOOK LIKE BELOW
