摘要:
Plastics extrusion is a highly cost-effective high-volume manufacturing process with wide-ranging industrial applications. To achieve a high-quality product, it is absolutely essential to have properly designed extrusion dies in order to obtain the correct velocity profile and temperature distribution during extrusion. This article describes an integrated application of CAD/CAM and finite element analysis to assist with the design of the multistage die for profile extrusion. Techniques for economic manufacture of the extrusion die by wire-cut EDM are also fully discussed.

摘要:
The use of CAD/CAM techniques for the design of a micromanipulator is described in this article. All design issues which address local and global objectives are analysed from the optimisation point of view. Computer simulations written in Fortran and APL, and three large-scale software application systems, CADAM, CATIA and CAEDS, are used to model, analyse and manufacture micromanipulator components. Both kinematic and dynamic model formulations are used to determine an improved, near optimal; design for the micromanipulator.

摘要:
This article focuses on the embodiment of product concepts, a ‘formal’ design activity in which it is proposed that computer-aided design (CAD) techniques can be effectively deployed, hence facilitating a simultaneous approach to the mechanical engineering design of products. The article also attempts to show that simultaneous concept development, through systematic procedure, is significantly dependent on multidisciplinary cross-functional team working.

摘要:
In 1983, the Electronics Industries Association published the standard RS-494, commonly referred to as BCL (binary cutter location) data exchange format. BCL is a means of standardising the formats for NC part programs. Its aim is to eliminate the cost and confusion associated with multiple postprocessors and enable the portability of part programs among different machine tools. In this article we give a short review of BCL and its introduction. We also discuss the nature of BCL data, its implementation aspects and the advantages it offers the NC industry.
