An algorithm is introduced which can generate the marking data for steel plate forming by line heating. A relatively simple mechanical model is adopted which can implicitly represent the complex physical phenomena of line heating. The general concept of the proposed algorithm is described and is applied to three types of surface models to show its validity and applicability. It is found that the proposed marking generation algorithm gives reasonable results of marking data where the estimated surface shows a nice agreement with the given surface. It can be said, therefore, that the proposed algorithm may be one of the feasible ways toward automation of plate forming by line heating. This paper ends with a brief discussion of the results and reference to the more general applicability of the present marking generation algorithm.
