Abstract

The hot and cold rolling and cold drawing processes are used in steel profile production to obtain special profiles with high levels of dimensional accuracy and quality. The wide range of applications and the variety of shapes lead to thousands of profiles. There is a need to classify and to codify shapes in order to reduce the time to design and to manufacture the profile tools. Pattern recognition has been used in this study and a method based on multiple circles-boundary intersection and form factor description is presented which is particularly suitable to steel profile production. The implementation of the method has shown that productivity is increased in the full design-through-manufacturing cycle. Furthermore, the computer aided retrieval of old shapes helps design standardization and reduces design proliferation and unnecessary part duplication.
