Hood design-Week 2

INNER PANEL CREATION:

STYLING SURFACE IS GIVEN AS INPUT.

TOOLING AXIS:

CREATE A LINE BETWEEN TWO EDGES AND MAKE A CENTRE LINE AS TOOLING DIRECTION.

FLANGE 1:

FIRST TRIM THE GIVEN SURFACE INTO HALF BY USING TRIM SHEET COMMAND.THEN OFFSET THE SURFACE FOR 1.7mm .THEN CREATE OFFSET CURVE IN FACE FOR 20mm.THEN USE TRIM SHEET COMMAND .FINALLY WE GOT OUR FIRST FLANGE.

FLANGE 2:

SIMILIARLY OFFSET SURFACE FOR 4mm AND CREATE OFFSET CURVE IN PHASE FOR 22mm AND 35mm.NOW TRIM THE SURFACE BY SELECTING THE NEEDED SURFACE AS OUTPUT.

FLANGE 3:

SIMILIARLY OFFSET SURFACE FOR 25mm AND CREATE OFFSET CURVE IN PHASE FOR 50mm.NOW TRIM THE SURFACE BY SELECTING THE NEEDED SURFACE AS OUTPUT.

FINALLY WE GOT 3 FLANGES AS OUTPUT.NOW USE THROUGH CURVES COMMAND TO JOIN THREE FLANGES.ALSO,USE FACE BLEND OPTION TO MAKE SHARP EDGE INTO FILLETED EDGE.

EMBOSS LAYER 1:

FIRST MEASURE THE STRIKER AND HINGES DIMENSIONS.NOW CREATE SKETCH BASED ON THAT VALUES TO PROVIDE CLEARANCE.THEN USE EMBOSS COMMAND AND CREATE DEPTH OF 10mm.USE EDGE BLEND OPTION TO MAKE SMOOTH EDGES.

EMBOSS 2:

BY USING THAT 10MM EMBOSSED SURFACE CREATE A SKETCH TO REDUCE THE FORCE WHEN CAR IS GETTING INTO AN ACCIDENT.TO REDUCE THAT WE NEED TO MAKE A Y OR V SHAPE SKETCH AND MAKE EMBOSS OF THAT SKETCH TO THE DEPTH OF 8.5mm.USE EDGE BLEND OPTION TO MAKE SMOOTH EDGES.

TRAJECTORY :

FIRST CREATE A POINTS BY USING HINGE AS REFERENCE.THEN JOIN THE POINTS BY USNG LINE.THEN CREATE A DATUM PLANE BY USING %ARC LENGTH OF 50%.NOW WE GOT DATUM PLANE AT CENTRE .THEN CREATE A SKETCH AND DRAW A CIRCLE OF 590mm.CREATE A STRAIGHT LINE AND ALSO CREATE A LINE OF 82DEGREE AND ALSO CREATE A TANGENT LINE.TRAJECTORY IS CREATED.

STRIKER AND HINGE:

FIRST CREATE A DATUM PLANE IN STRIKER BY USING %ARC LENGTH AS 50%.WE GOT THESE AS INPUT.NOW CREATE A ASSEMBLY OF THESE STRIKER AND HINGES AND USE TOUCH,ALIGN AND PARALLEL CONSTRAINTS.NOW STRIKER AND HINGES ARE ALIGNED PERFECTLY.EXTRACT THE BOTTOM SURFACE OF THE STRKER.EXTEND ITS CURVE TO GET MORE CONTACT WITH THE INNER PANEL.THEN USE LAW EXTENSION .NOW WE TO USE TRIM AND EXTEND COMMAND TO MAKE CORNER.

INNER PANEL IS COMPLETED.FINAL WE HAVE TO MIRROR THE ENTIRE ASSEMBLY.

OUTER PANEL AND HEMMING PROCESS:

TRIM THE GIVEN OUTER PANEL INTO HALF.NOW USE BRIDGE CURVE OF 8mm TO MAKE CURVED EDGE.TO CREATE HEMMING PORTION, OFFSET THE SURFACE FOR 2.65mm AND TRIM THE UNWANTED SURFACES.NOW CREATE A 0.1mm OF OFFSET CURVE IN FACE AND USE LAW EXTENSION COMMAND TO MAKE A SURFACE.NOW USE THREE FACE BLEND COMMAND AND JOIN THE THREE FACES.NOW WE GOT THE HEMMING PORTION AS WELL.USE MIRROR COMMAND HERE AS WELL TO GET A COMPLETE SURFACE.ALSO WU NEED TO CREATE HEMMING RELIEF OF 3mm.TO CREATE THAT USE OFFST CURVE COMMAND AND CREATE POINT USING IT .NOW WE GOT REQUIED HEMMING RELIEF.NOW TRIM THAT PORTIONS AS WELL.

FINALLY WE GOT OUR HOOD AS AN OUTPUT.TO ELIMINATE SHARP EDGES USE EDGE AND FACE BLEND COMMANDS.

FINALLY USE THICKEN COMMAND OF 0.75mm.

OUTER PANEL-SHOULD BE THICKENED DOWNWARDS.

INNER PANEL-SHOULD BE THICKENED INWARDS.
