An engineering workbench for industrial applications of rapid prot typing techniques

Objective



While Rapid Prototyping (RP) processes can generally
produce a physical model much faster than traditional
manufacturing processes, they also set a number of new
requirements for process planning and data processing.
Those new requirements make the data preparation
complicated and frequently very time consuming. It is
recognized that the software interface is the bottleneck
in today's RP applications. Further, with continuous
improvements of RP processes, the importance of Rapid
Prototyping is shifting towards the development of
process chains such as in tooling applications and
reverse engineering. The question one faces here is not
only how to obtain prototype models but also how to
generate models which can be used for subsequent
processes.
To break the software bottleneck in RP applications, the
proposed project aims to develop a so called RP
engineering workbench providing a set of functionalities
in an integrated form to handle these RP specific process
planning and data processing problems. The workbench
consists of five main modules:
A 3D manager, interfacing CAD systems via neutral data
formats (IGES, VDAFS and STEP) and visualizing and
correcting CAD models for RP processes
A layer manager, interfacing 2D layer data from
different sources as well as its visualization and
correction
A process manager, generating RP process related
information such as support structure, optimal part
orientation and 3D nesting as well as performing process
simulation and manufacturing time and cost estimation
A process chain manager, supporting the development of
process chains especially for metal casting processes
and reverse engineering
A communication manager, providing WWW based "software
on demand" service in both internet and intranets as
well as supporting cooperative work between CAD
designers, RP users and casting manufacturers.
The consortium comprises a manufacturer of RP machines
and system software, a software house specializing in the
development of RP application software, a research
institute for the development of RP specific geometric
algorithms, two RP service bureau and three foundry users
and process chains developers.
