Week 9 - Challenge 2 - Switch Bezel Design

REPORT ON SWITCH BEZEL DESIGN:-

STEPS TAKEN TO CREATE THE SWITCH BEZEL DESIGN ARE AS FOLLOWS:-

1.INPUTS:-

HERE WE WILL RECEIVE THE CLASS A SURFACE AS AN INPUT FROM WHICH WE CREATE CLASS B AND CLASS C SURFACES TO FORM A SOLID 3D MOLDEL AS SHOWN IN BELOW FIGURE.

2.TOOLING AXIS:-

TO CREATE AN TOOLING AXIS WE WILL ANALYSIS THE CLASS A SURFACE IN SUCH A WAY THAT ALL THE FACES PRESENT IN IT NEED TO CLEAR IN THE CAVITY SIDE.
HERE WE HAVE TO EXCLUDE THE FILLETS AS IT CREATES PROBLEM DURING OFFSET.
IN THE GIVEN CLASS A SURFACE WE HAVE 3 FACES WHICH IS TO BE CLEARED AND 2 FACES WHICH IS PERPENDICULAR TO THE DUMMY AXIS.

TO CLEAR ALL THE 3 FACES WE NEED TO DRAW THE SKETCHES ALONG X AND Y AXIS, AS Y CONSISTS 2 FACES AND X CONSISTS 1 FACES.
INITIALLY WE WILL CREATE THE SKETCH ALONG Y AXIS AND BY USING INTERSECT 3D ELEMENT COMMAND WE GET THE INTERSECT ALONG Y AXIS, WHERE THE LINES ARE DRAWN, BISECTED TO GET A DUMMY TOOLING AXIS.

SIMILARLY WE WILL CREATE THE SKETCHE ALONG X AXIS AND BY USING INTERSECT 3D ELEMENT COMMAND WE GET THE INTERSECT ALONG X AXIS, WHERE THE LINES ARE DRAWN, BISECTED TO GET A DUMMY TOOLING AXIS.

BOTH DUMMY TOOLING AXIS ALONG X AND Y AXIS ARE THEN BISECTED TO GET A TOOLING AXIS INDICATED IN BROWN COLOUR AS SHOWN IN BELOW FIGURE.

3.SWITCH BEZEL DESIGN:-

A.CLASS B SURFACE CREATION:-

INITIALLY SWITCH BEZEL REST IS CREATED BY USING TOOL LIKE EXTRACT, UNTRIM AND OFFSETED AT 2.5MM FROM CLASS A SURFACE AS SHOWN IN BELOW FIGURE.

SIDE WALLS ARE CREATED BY USING THE TOOLS WHICH ARE SHOWN IN BELOW TREE STRUCTURE.

THE BASE ARE FORMED BY USING THE TOOLS LIKE EXTRACT, UMTRIM AND OFFSETED AT 2.5MM AS SHOWN IN BELOW FIGURE.

FINALLY THE TRIM TOOL IS USED TO FORM A CLASS B SURFACE AS SHOWN IN BELOW FIGURE.
THE FILLET VALUE GEOMETRICAL SET IS CREATED TO GET THE FILLET VALUE FROM THE CLASS A SURFACE.

B.CLASS C SURFACE CREATION:-

CLASS C SURFACE IS FORMED BY USING THE MULTIPLE EXTRACT TOOL, SMOOTH CURVE WHEREVER THE GEOMETRY IS COMPLEX AND SWEEP COMMAND WHERE DRAFT DIRECTION IS ALONG THE TOOLING AXIS.
THE TREE STRUCTURE INDICATES THE TOOLS USED WHICH ARE SHOWN IN BELOW FIGURE.

C.FINAL TRIM:-

IN THIS GEOMETRICAL SET WE WILL JOIN BOTH CLASS A AND CLASS C SURFACE AND THEN TRIM WITH CLASS B SURFACE TO GET THE SWITCH BEZEL 3D MODEL AS SHOWN IN BELOW FIGURE.

4.DRAFT ANALYSIS:-

HERE WE WILL CHECK THE DRAFT ANGLES USING FEATURE DRAFT ANALYSIS.
THE DRAFT ANGLES ARE OBTAINED IN THE FORM OF COLOUR CODES.
INITIALLY SELECT THE COMPASS AND PLACE IT ON THE TOOLING AXIS AND LOCK THE DRAFT DIRECTION.
SELECT ON THE SURFACES THAT TURNS INTO GREEN COLOUR WHICH INDICATES THE DRAFT ANGLE OF 2.9 DEGREES, IF THE SURFACE BECOMES RED THEN THE DRAFT ANGLE IS IN NEGATIVE WHICH MEANS IT CANNOT BE CLEARED IN THE CAVITY SIDE AS SHOWN IN BELOW FIGURE.

5.CLOSE SURFACE:-

HERE THE HOLLOW SURFACE WHICH IS OF CLOSED BOUNDARY IS CONVERTED INTO A SOLID 3D MODEL USING CLOSE SURFACE TOOL IN PART WORKBENCH AS SHOWN IN BELOW FIGURE.

6.ORIENTATION VIEWS:-

7.PUBLICATIONS:-

AS PER THE REQUIREMENT CLASS A, CLASS B, CLASS C SURFACES AND TOOLING AXIS ARE PUBLISHED ARE AS SHOWN IN BELOW FIGURES TREE STRUCTURE.
