Master Section of Plastic Product design Using CATIA V5
AIM : To create closed volume of Surface using Master section of Class-A surface.
DESIGN METHOD :
- Measure all dimension Master section.
- Start with Generative Shape Design.
- Create B-side features (if applicable).
SOFTWARE : CATIA V5
INTRODUCTION :
Master sections are the guides for design requirements which decide the component packaging after technical (Styling, Concept or Class-A) surfaces.
Concept development in BIW
Concept & Feasibility
•Concept design / Design support and feasibility study
•Concept surface description
•Generate master sections and component packaging
•Technical surface description (A class)
•Deciding part configuration / split lines
•Gap & Flush requirement
•Feasibility study & simulations
•Assembly sequence & develop process diagram & spot plan drawings
•Preliminary weight analysis and bill of material
Package analysis
•Interior, exterior, engine, underbody, and luggage compartments
•Engine and passenger compartments
•Closures
Detail Design
•Modeling & drafting of vehicle components
•Sub assemblies & assemblies: Body in white, closures
•Tolerance analysis
Facelifts and Variants
•Minor freshening: rub rails, door trims, steering wheels, roof carriers, and decorative trims
•Moderate facelifts: bumpers, spoilers, grilles, steering wheels, door trims
•Mid-life facelifts: changes in bumpers, lamps, instrument panels & consoles, spoilers, grilles, steering wheels, door trims, new engine, RVMs, BIW changes to suit trim changes
•Major Facelifts: carryover platform
•Variants: from base hatch back platform to sedan and station wagon with or without W/B increase
Engineering Documentation
•Bill of Material generation and controlling
•Material specifications
•Chain of Dimension, Gap and Flush study and GD&T on drawings
•Design Failure Mode Effective Analysis (DFMEA)
•Product specifications, Design Validation Plan (DVP)
•Fastener selection
3D-engineering, 2D-drawings releases
•Body contour development
•Design according to tool, manufacturing or process requirements
•FMEAs
•Data management and Releasing
Geometrical Integration / Digital Mock Up (DMU):
•Package
•Collisions-check
•Design studies
