Extension of functional possibilities of tools is one of the main ways to increase the maintenance property of technical means. It especially actually in modern agricultural production, based on precision agriculture technologies, where using technical means must provide: reduction of cost, conservation of ground fertility, saving energy-resources, improvement labor conditions, and increase machines capacity. One of efficient way to solve these problems is using geometric modeling methods and systems in designing technical means. Geometric modeling, as one of the varieties of the synthetic methods of design, is a theoretical base for different technologies of these methods, like industrial design and CAD technologies. In this chapter, as examples, the following case studies will be considered: development of multifunctional mold board by geometric modeling, for increasing its maintenance property; integration role of CAD technologies in PLM, including in maintenance management; and visualization of production design process of technical means according to maintenance criterions.

Geometric modeling, as widely used synthetic design method in design engineering and manufacturing, is a theoretical base for geometric modeling application (industrial design) and geometric modeling systems (CAD systems). Therefore this chapter is devoted to application geometric modeling methods and systems in design engineering and manufacturing. For example, we will considered designing agriculture machines’ tools by following case studies: development models of bulldozer’s moldboard by geometric modeling method (for design engineering); screening the concept select process of plow’s moldboard (for design engineering and manufacturing); determining integrative role of geometric modeling systems in agro machinery tools’ PLM (for manufacturing).

This chapter examined the theoretical background of the use of a screw working body in front of the planner bucket and conducting experiments in laboratory conditions with the proposed working body. This work supports the practical solution of using a screw working particle in the current field planning. Significance of the work reducing traction resistance to soil movement up to 20% enables the tractor unit to work at higher speeds of translational motion; the latter contributes to increased productivity, improved planning quality and reduced cash costs per unit of work performed. The chapter was prepared under results of research in the Mechanics Laboratory of Bukhara Engineering Technological Institute.
