The production of rolling steel is a complicated process which includes management of production operations and production process. The former includes costs accounting, procurement plan of raw materials and auxiliary materials and quality control. The latter includes devices, technology and production rhythm of iron making, steel making, casting and rolling. Nowadays, the departments of these two have adopted the computer managing system to improve the efficiency of management. But the concept of collective design of CIMS is not considered thus the computer control system and operations management computer system are isolated. Furthermore, resources are not shared and information is not integrated among the systems thus enterprise competitiveness decreases. This paper designs the rolling steel computer aided manufacturing system based on internet and introduces the three levels system structure of CIMS technology strategy as well as the key technology. This study is of great significance not only in the integration of rolling steel production systems and the sharing information, but also in upgrading the steel enterprises, reducing costs and increasing enterprise competitiveness.

Profiled Edge Lamination (PEL) tooling is a promising Rapid Tooling (RT) method involving the assembly of an array of laminations whose top edges are simultaneously profiled and beveled based on a CAD model of the intended tool surface. To facilitate adoption of this RT method by industry, a comprehensive PEL Tooling Development System has been proposed. The two main parts of this system are (1) iterative tool design based on thermal and structural models and (2) fabrication of the tool using a Computer-aided Manufacturing (CAM) software and Abrasive Water Jet (AWJ) cutting. CAM software has been developed to take lamination slice data (profiles) from any proprietary RP software in the form of polylines and create smooth, kinematically desirable cutting trajectories for each tool lamination. Two cutting trajectory algorithms, called Identical Equidistant Profile Segmentation (IEPS) and Adaptively Vectored Profiles Projection (AVPP), were created for this purpose. By comparing the performance of both algorithms with a benchmark part shape, the AVPP algorithm provided better cutting trajectories for complicated tool geometries. A 15-layer aluminum PEL tool was successfully fabricated using a 5-axis CNC AWJ cutter and NC code generated by the CAM software.
