Computer Integrated Design and Analysis for Machine Tool Components

CIDAM - CP93-7832

Keywords: software tools, CAD, FEM, product modelling

Start Date: 1 February 94 / Status: finished / Duration: 17 months

Objectivies and Approach

The aim of this project is to develop an integrated system for the design and analysis of machine tool frames. The system is based on a common product model used by existing computer aided design (CAD) and finite element modelling (FEM) software and on flexible communication mechanisms for data exchange. Development of algorithms for the calculation of the non-linear elastic behaviour of guides and pairs of contacting rough surfaces will also be undertaken.

The system will consist of four modules:

a CAD system completed by parameterised geometry models for every machine element and form features for the design of machine tool frames. By selecting these elements and combining them geometrically, a 3D product model for a machine tool may be obtained which can be stored in a common database in terms of objects.
a module that allows automated and manual conversion of product models into FEM meshes.
an FEM-based iteration algorithm for the calculation of non-linear effects.
a communication mechanism based on the principles of client-server architectures.
