Products by Rapid Integrated Detailed Engineering

Objective


The development of the PRIDE prototype hybrid object modeller resulted in the preparation of a set of software tools that will collaborate to support the detailed engineering for manufacture of complex castings and other parts in the following areas:
- detailed modelling of incompletely specified areas, including using data digitised from physical models;
- preparation of representations for analysis and manufacture;
- adjustment of detailed models to meet performance and manufacturing criteria;
- prototype manufacture for form/fit and performance testing.

In addition a methodology for the testing and adjustment of designs to improve/optimise performance and quality of the part or the manufacturing process was developed. Furthermore the project contributed to the development and testing of the DMAC OLE for D&M standard industry technology for the integration of computer aided design and modelling applications.

In detail the PRIDE Hybrid Object Modeller resulting comprises:
a) background commercial CAD,CAM CAE and simulation software that was ported to the Microsoft Windows environment;
b) DMAC industry standard interface software that was developed and integrated into the CAD,CAM CAE and simulation software to provide the key server and client applications needed for the PRIDE domain;
c) additional software written and integrated into the background commercial CAD,CAM CAE and simulation software to tackle the bottleneck issues identified by the industrial application experts in the Consortium.
The world wide competition for the supply of engineering components makes competitiveness in terms of product functional performance and lead time a critical survival issue for many European companies. This has led manufacturers of complex engineering castings and mouldings to develop a strong requirement for a practical
multidisciplinary design optimisation (MDO) approach based on detailed design, analysis and manufacturing simulation technology.

The introduction of design optimisation techniques in this domain is being seriously impeded by the lack of a method of shape description that can be controlled by a
very small number of key parameters. Another obstacle is the lack of an appropriate open environment supporting closely co operating multi vendor tools for design and
manufacturing complex shaped parts. The PRIDE project will address this important industrial need by developing the computer based technology needed to support
multidisciplinary design optimisation (MDO) and validating the approach for the engineering component industry. PRIDE will build on CAD/CAM and CAE technology
from its developer partners to develop an easy to use hybrid object modeller (HOM). The HOM will include a highly innovative approach to the parametrisation of
complex shapes with a very small number of key parameters such that these shapes can be optimised for performance and manufacturability as measured by CAE tools. The HOM will be based on an open mechanism for linking CAD/CAM/CAE servers from different software vendors.

The industrial objectives of PRIDE are:
1. to devise a practical MDO approach for engineering parts with complex geometry, e.g. machined castings;
2. to demonstrate that the functional performance of case study products can be improved to a significant degree by the application of an MDO approach;
3. to demonstrate that the MDO approach can reduce lead times by 15 30% (and in some cases considerably more), illustrated by case study products;
4. to ensure that the technology developed in this project can be applied equally well to a range of other complex shaped products with similar improvements in performance;
5. to demonstrate an open approach that allows SME's to assemble a tailored multidisciplinary design, analysis, simulation and manufacturing environment from their choice of appropriate software tools;
6. to ensure that the technology developed in the project can be run on a Pentium PC or equivalent.

The final results of this project will be practical examples of MDO applied to case study castings as well as a prototype ybrid object modeller which will support:
- detailed modelling of incompletely specified areas, including using data digitised from physical models;
- preparation of related representations for analysis and manufacture;
- adjustment of detailed models to meet performance and manufacturing criteria;
- prototype manufacture for form/fit and performance testing;
- testing and adjustment of design to improve/optimise.

The PRIDE consortium has strong industrial resources with three user partners, who bring expertise in patternmaking and rapid prototyping (Websters), design and manufacture of complex diecastings (Gilardoni) and casting of steel parts (Ferespe). It also includes a leading European CAD/CAM software house (Delcam), a university with strong research background in geometric modelling and CAE (UNIVLEEDS), a research organisation with specialism in CAE (Cetim), a software house expert in casting simulation (RWP). The project will last 36 months employing 35.5 man years of effort from partners in 5 countries.
