CATIA FEA

WEEK - FINAL PROJECT : DEVELOPMENT OF A DOOR TRIM PANEL

AIM : Creation of CAD model considering following inputs as like in OEM and tier1 companies.

a) Class A surface

b) Nominal thickness

c) Attachment strategy

SOFTWARE USED : CATIA V5

OUTPUT REQUIRED

Positioned Sketch
All Dimension are ISO-CONSTRAINED.
Chronological order of Tree Structure.
Proper Geometrical set nomenclature.
Ensure proper Tooling Axis.
Provide proper Thickness as per Design Rules.
Create the mounting features as per Design Guidelines.
Draft and Tooling Analysis.

PRIMARY STEPS INVOVED

As Class A surface is given of Four sub parts of DOOR PANEL.

BOTTOL HOLDER
DOOR ARM REST
LOWER SUBSTRATE
MAP POCKET

2. We work Differents parts one by one, Creating Class B Surface, Creating Class C Surface, Creating TOOLING AXIS, Adding Requied Engineering Components, Draft analysis.

3. At last All CATPART file will get assembled in one CATPRODUCT Assembly file.

STEP 1 : -

DOOR ARM REST :

As there is Discontinuity in Class A surface showing Two Domains of curve after Disassembling the Boundary.

LOWER SUBSTRATE

As there is no Discontinuity, Therefore it is showing only Single Domain of Curve.

MAP POCKET

As there is no Discontinuity, Therefore it is showing only Single Domain of Curve.

BOTTOM HOLDER

As there is no Discontinuity, Therefore it is showing only Single Domain of Curve.

STEP 2 :- CLASS 'A' SURFACE IMPROVEMENT

BOTTOM HOLDER, LOWER SUBSTRATE, MAP POCKET DOES NOT HAVE ANY DISCONTINUITY.

STEP 3 :- TOOLING AXIS

Analyse the best possible tooling Direction for which while Ejecting product less will be the Damage or zero damage.
For creating TOOLING axis Extract the desire face from class A surface, create point and plane at center and give direction to tooling axis.
