Urgency of the research. 3D geometric modeling, the use of which increases the level of competitiveness of production is widespread in countries with developed machinery.

Target setting. The creation of new high-performance methods of grinding of cylindrical shafts requires the development of new interconnected modular 3D tool models, processes of stock removal and shaping.

Actual scientific researches and issues analysis. The works devoted to the development of 3D geometric modeling present three-dimensional model stock removal and shaping of cylindrical surfaces with a round grinding, show modular 3D modeling tools, forming parts for different grinding machines.

Uninvestigatigated parts of general matters defining. Modular 3D geometric models of stock removal and shaping of cylindrical shafts for new methods of its grinding are not represented in the worksdevoted to this subject.

The research objective. The objective of the paper is the creation of common modular 3D tool models, processes of stock removal and shaping of machined cylindrical shafts surfaces using standardized modules (tools, guidance and shaping) in the grinding with crossed axes of wheel and details.

The statement of basic materials. A new high-performance single pass deep grinding with crossed axes of the grinding wheel and cylindrical shaft are presented and modular 3D model tools, processes of removal allowance and forming are developed. Tool and workpiece contact patch are defined, process performance model are created and the parameters of the orientation of the wheel, which provide obtaining predetermined accuracy, the geometric roughness of parts and increase processing performance, are calculated.

Conclusions. The present method of grinding cylindrical shafts provides the increasing of processing performance and the accuracy of shaping parts, obtaining a predetermined geometric roughness and uniform wear of the grinding wheel.

Key words:

modular three-dimensional geometric modeling, cylindrical shaft, shaping, stock removal, grinding wheel, skew axes
