The paper reviews the issues of source data generation for automated design of the technological process of machining and geometric information transfer from one design stage to another. When dealing with design issues, the input of source data related to the work-piece and manufacturing conditions plays an important role. The formalized description of these objects is carried out using mathematical models. A drawing of a machine-building part or work-piece is a geometric model of the manufacturing item. However, this model is inconvenient when establishing links in the design of its manufacturing processes. Drawing models are the basis of graphic modules of computer-aided design systems. However, they are inconvenient for achieving process design goals, since the object is known to be surface in machining or assembly process, but not zero-dimensional objects on the plane. It represents a mathematical model of a machine-building part consisting of the basic elements of the form, which can be used in the automated development of the technological process of machining.
