Computer-Aided Design and Manufacturing for Extrusion of Aluminum,Titanium and Steel Structural Parts. Phase II. Application to Practical Extrusions. Volume II. User's Manual for ALEXTR System of Computer Programs for Design and Manufacture of Flat-Face Dies for Aluminum Extrusion.

摘要

The overall objective of this program was to develop practical computer-aided design and manufacturing (CAD/CAM) techniques for extrusion of aluminum alloys, steels and titanium alloys. Phase II results can be summarized as follows: The computer-aided manufacturing and NC techniques developed in Phase I were extended to make 'SHAPE' computer system applicable to extrusion of structural shapes, such as L's and T's. ALEXTR computer system for nonlubricated extrusion of aluminum alloys was developed. An economical-technical evaluation of the usefulness of CAD/CAM system in extrusion was performed. This study showed that utilization of CAD/CAM systems developed in this program can reduce manufacturing costs, improve delivery schedules, and increase the productivity of extrusion operations.
