Automatic Identification and Description of Surfaces in 2D Drawings
The paper describes one of the stages of building an automated system for technological preparation of production. Generalized algorithms for the formation of the technological process and the route technological process are presented. As part of the automation of the design of technological processes, the task of preparing the initial information for creating a digital route map of the technological process in a semi-automatic or automatic mode is solved. A standard two-dimensional drawing of a part acts as design documentation at the input to the design system. The software system used in the work allows identifying and describing the main types of surfaces presented in the drawing. The program works with a graph representation of a drawing image, which can be preliminarily vectorized. The paper describes the stages of drawing processing, as well as a flowchart of the recursive procedure, which is the core of the identification of the main surfaces. The information obtained during the identification process allows proceeding to the next stage of the route technological process - the choice of types of part processing.
