Abstract : Guide rails are one of the most important components in terms of equipment because the quality of the linear rail in-fluences on the
precision linear motion. For long rails used in the guide rail, high dimensional accuracy as well as a cross-sectional shape is required. As
a production method of guide rail, drawing process is mainly used. But, the shape rolling process is open used for the pre-process of the
other metal forming process such as forging, extrusion, and shape drawing. The shape rolling process is one of the most effective processes
which can make long products with constant irregular cross-sectional shape. Therefore, the tool shape is a very important process
variable to obtain the required final product. The objective of this paper is the design of roll shape of the rolling process to produce the
initial material with irregular cross sectional shape for shape drawing. Also, the die shape of the drawing process is determined to satisfy
the dimensional accuracy of the final product. In this study, FE-analysis and artificial neural network (ANN) were applied to achieve the
objective. Further, shape rolling and shape drawing experiments were performed to verify the result of FE-analysis. From results, it was
possible to design the roll shape of shape rolling process effectively.
