Week 8 - Challenge 2 - Switch Bezel Design

AIM: To create the Switch Bezel Plastic component through the given Class-A surface.

OBJECTIVE: The objective is to begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

PROCEDURE:

TOOLING AXIS

DRAW TWO SKETCHES FOR TO REFERENCE DIRECTIONS

AND BY USING THOSE LINES; USIE BISECTING LINE COMMAND TO CREATE TOOLING AXIS

B SURFACE CREATION

B SURFACE CREATION IS DIIDED IN 3 PARTS

1. BEZEL SURFACE, 2. WALLS, 3. BASE

1. BEZEL SURFACE

COMMANDS USED:- EXTRACT, UNTRIM AND OFFSET

2. WALLS

COMMANDS USED:- EXTRCT, UNTRIM, EXTRAPOLATE OFFSET, TRIM

3. BASE

COMMANDS USED:- EXTRACT, UNTRIM, EXTRAPOLATE, OFFSET

THEN BY USING TRIM COMMAND AND AFTER GIVING REQUIRED FILLETS E GET AN B SURFACE

SOMETIMES WE NEED TO DO SOME EXTRA WORK TO FIND OUT THE EXACT VALUE OF FILLET

i.e. EXTRACT THAT FILLETED FACE AND UNTRIM IT, AND MEASURE THE VALUE(THIS IS REQUIRED FILLET VALUE)

C SURFACE CREATION

C SURFACE CAN BE CREATED BY USING EITHER EXTRACT OR BOUNDARY COMMAND

WE FIND SOME SMALL SMALL FACES TO OVERCOME THIS USE SMOOTH CURVE COMMAND.

FINAL STEP

THE JOIN CLASS A AND CLASS C SURFACE

IN IT SOMETIMES WE MAY FACE ERROR i.e GAP

THEN TO SOLVE THIS;

EXTRAPOLATE CLASS A SURFACE BY SMALL VALUE AND THEN TRIM IT

BOTH THE COMMANDS ARE SIMILAR(JOIN AND TRIM) DIFFERENCE IS TRIM IS CORRECTED.

FINAL TRIM AND WE GET THICKEN PART.

CLOSE SURFACE.
