Week 11 - Final project
AIM:
To create the automotive door trim panel from the given class A surface and a thickened part with the required features to locate, mate and assemble the components.
OBJECTIVE:
The door trim panel with the necessary surfaces developed along with the engineering features on the B side surface that constraints with the design standards in the industry. The component when separately created and the features also must follow the draft conditions which inturn ensures the manufacturing or the mould feasibility.
New Product Development - NPD:
The process which involves forming strategy, organizing requirements, generating concepts, creating product & marketing plan, evaluating and subsequent commercialization, thereby bringing a new product to the marketplace.
Product development is a complete cycle which starts from market analysis, product specifications to concept/industrial design, costing, scheduling, testing, manufacturing and ends at logistics, customer feedback, improvements and the final act of getting a product into the market.
This is the procedure followed in the same door trim panel where here a portion is taken out of the entire process and worked on like developing the part component and mating, assembling the components together along with the features necessary to carry out the commands. Also, to ensure and avoid the plastic defects that may arise due to improper or poor design aspect.
DOOR TRIM PANEL:
The door trim panel is one of the major component that make up the interior of an automotive. Generally, they are made out of ABS, or Polycarbonate to withstand higher impact forces. An illustrative of an door trim is given below.
CLASS A SURFACE:
The class A surface along with the master section for development is fed into the new poroduct under the assembly workbench.
The complex surface is separated initially into separate components. They are extracted and then put under as separate products.
DRAFT ANALYSIS:
Then with these surfaces the draft analysis on the component is carried out. Initially, the toolin direction for the surface is determined and then the mould feasibility is analyzed.
As we can interpret the upper substrate is clearing out the 3degree draft and the part can be created out of the surface as this ensures the manufacturing and tooling feasibility.
Then the same analysis is carried out for the other surfaces too.

SURFACE MODELING:
Once the draft analysis is carried out the surface can be created into the part components.
UPPER SUBSTRATE:
The B surface is given an offset to the thickening of the component and then inspected and patched if any surface irregularities exist in according with the Class A.
Then the boundaries are swept along with the draft angle from the class A surface to create the C surface.
Which are then trimmed together to obtain the final component output.
The surface modelled component is then inspected for any extruded or irregular patches using the boundary condition.
Then the surface is closed and filled in the part workbench to get the final component.
