Abstract
Metal drawing, unlike other classes of engineering work, has proceeded mostly as an art rather than a science. The empirical method has of necessity been the basis of advancement, due to the limited knowledge of the attending phenomena.
The purpose of this study is to foster the development of analysis in drawing as an aid to subsequent development. Toward this end no attempt has been made to set forth any concrete analysis, since the subject is regarded as too complex for such a discussion at present. However, as a preliminary step in this direction, an attempt is made to outline a manner of attack by which a proper conception of the phenomena may be realized. For the present a general discussion is made of the manner of working the metal with reference to its state end behavior in comparison with that found in drawing. A survey of the conditions observed in the forming of a stamping is also made along with a report of certain experimental investigations which were conducted by the author.
