Computer modeling the moldboards’ surface in autocad system

Abstract There are considered the tasks of the computer modeling of moldboard’s working surface in the article. The proposed solution was developed by geometric and computer modeling of moldboard’s working surface elements. As surface elements were chosen the frontal contour, a directory curve, and the generative lines with their pre-set conditions, which were given by specialists. The geometric models of working surface elements, which were developed based on research results were implemented in the AutoCAD system. The researches were carried out using the constructive geometric modeling methods and systems and based to surface modeling methods of Descriptive Geometry and traditional methodology of designing the moldboards. The proposed models, algorithms, and methodology can reduce the design period, simplify the geometric parameters setting, and facilitate the work of designers. The solution is required in educational, research, and production processes in Agriculture Engineering and can be used in developing other technical objects with geometrically complex surfaces.
