Abstract
One of the most important aspects in multi-stage shape drawing is the proper design of the intermediate dies especially to provide adequate metal distribution. In the current study, a method for designing the intermediate dies has been developed to manufacture hollow linear motion guide rails by multi-stage shape drawing. The design method is based on the modified virtual die method. The effectiveness of the proposed design method was verified by FE-simulations and experiments using Mn55Cr carbon steel. From the results of the FE-simulations and the experiments, the proposed design method led to a drawn product with a sound shape. The dimensional tolerances of the product were within the allowable specified tolerances.
