摘要:The main characteristic of machine tool system, providing the most efficient multi-axis processing, is machine volumetric accuracy, which may be demonstrated in the machine working space. The development of methods and means of controlling volumetric accuracy is a very important engineering and process task.Solving this issue may ensure competitive ability of the domestic fixtures and tools for multi-axis form making during the treatment with the help of power tools. Early project stage is the most important one, as the success of the machine project itself highly depends on the right choice of arrangement. In this research, we presented design scheme of machine-tool unit, stated its initial and boundary conditions, and also there was developed a model of comparative assessment of elastic displacement in the working space. Volumetric accuracy is formed by means of inaccuracy space field of the processing system, which occur in the formation zone under the influence of agitation, which may be determined by simulation and analytical modeling of machine tool system. Within the framework of this research, there was developed the method of comparative assessment of volumetric accuracy of multi-axis machine compositions with not less than 5 interpolate axis.
