Study on skin panel modeling and its drawpiece design 2000-05-0271
With rapid progress of information technology, computer has been
applied broadly and heavily into automobile panel design and
manufacturing. In order to survive in the market and meet various
demands of customers, the paper brings out about the integrated
design method that considers the whole life cycle of part
development and makes data flow fluently between part modeling and
CAD model is very important in the product defined digital
model. This gives a summary of panel modeling process based upon
the point of application and many examples. There is a detail
description on some important issues relevant with part modeling
such as modeling types, key techniques and challenges.
The panel dies have serious effect on the part quality and
design to consistency. It is necessary to define the features
respectively and append machine feature to the design features, so
that CAM module can read CAD data directly and make the integrated
Process planning is the link between CAD and CAM. The design
drawpiece influences the quality of NC programming and machining.
The paper describes some researching work on drawpiece planning
with many cases of design.
The integration of panel design and manufacturing is a general
trend. In the mode of integrated environment, all the relative
elements in the whole design should be considered synthetically,
which will lead to its automation and intelligentialize of part
