CATIA

Door Trim

Objective:

Development of a Door Trim panel

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

Things to consider during this project:

To create the individual tooling axis for the part and perform the draft analysis for given class A surface.
To create the class B and C surface with reference to given class A Surface

Input

Class-A surface and master section for Engineering Features

Component included in Door Panel

Arm Rest
Lower Substate
Bottle Holder
Map Pocket

Design Procedure

1. Arm Rest

Extracting the Given Class-A Surface in Arm Rest

Checking the surface quality of class A surface

Improvised Class-A Surface

Creating Tooling Axis

Tooling Axis 1

Method Used: Normal to Surface

Tooling Axis 2

Method Used: Bisecting Method

Pulling the reference from the master section in order to make a second tooling axis for clearing class A and engineering features.

Draft Analysis Result w.r.t. Tooling Axis 1

Red and Blue colour area are visible, which is not getting cleared with Tooling Axis 1

Draft Analysis w.r.t. Tooling Axis 2

The above mentioned unclear area is clear w.r.t. Tooling Axis 2

Creating Class B Surface

Measuring the offset distance between the Class-A & B Surface with Master Section

As per the master section we are going to give Class-A surface offset of 2.5mm

Creating Class-C Surface with reference to Class-A Surface

Creating the closed body by joining the Class-A, B and C surface

Creating the flanges on Arm Rest

W.R.T. master section we will get to know the dimension of flange and with respect to counterpart position of heat stakes and locating ribs of Lower Substrate position.

Engineering Features Draft Analysis

Feature Tree of Arm Rest

2. Lower Substrate

Extracting the Class A Surface from the Input

Tooling Axis

Method used: Bisecting method w.r.t. to master section

All the surfaces are getting cleared with the current tooling axis.

Creating the Class B Surface

Measuring the distance between the class A and B surface

As per the master section the distance between the class-A and B surface is 2.5mm

Creating Class-C Surface with reference to Class-A Surface

Closed Surface

Creating the closed body by joining the Class-A, B and C surface

Closed body draft analysis

Creating of Heat Stakes, Locator Ribs and Dog House

Heat Stakes

Extracting the inputs from the master section

Adding draft on both surfaces of 0.5° w.r.t. tooling axis

Adding draft analysis of 0.5° w.r.t. tooling axis

Applying Union trim on both the bodies to make a Heat Stakes

Dog House

Closed body surface

With pocket command we will remove the material for push pin

Applying the fillet and draft on dog house

Once after the translation of heat stakes and dog house to all the location, we will perform the draft analysis.

Feature Tree

3. Bottle Holder

Extracting the class-A surface from the input

Performing the surface quality check

Creating Tooling Axis

Method Used: Normal to surface

Draft Analysis of Class-A Surface

Note: Few surfaces are appearing in blue and red which are not getting clear, hence need to reach out to class-A surface creator team for updated model.

Creating Class-B Surface

Creating Class-C Surface with reference to Class-A Surface

Closed Body

Creating Flanges on closed body

W.R.T. respect to counterpart position of heat stakes of Lower Substrate position, we will add the flange on those location

Final Draft analysis for flanges

Feature Tree

4. Map Pocket

Creating Class A surface

Extracting Class-A surface from input

Creating Tooling Axis

Method Used: Normal to Surface method

Draft analysis of Class-A surface

Creating Class B Surface

Measuring the offset distance between the Class-A & B Surface with Master Section

As per the master section, we need to give offset of 2.5mm for Class-B surface

Creating Class C Surface

Creating the closed body by joining the Class-A, B and C surface

Creating Flange

W.R.T. master section we will get to know the dimension of flange and with respect to counterpart position of heat stakes and locating ribs of Lower Substrate position.
