Tignibidin A. V., Zherebtsov S. N. — Effect of the effective grinding forces on working error

The sizes of elastic deformation of processed details in diameter from 3 to 10 mm on circular grinding machine tools are resulted and influence of axial loading on rigidity of details in the machine tool centers is shown. Schedules of dependence of elastic deformation from forces of cutting in comparison with theoretical calculation are received. It is proved that axial loading on a detail at grinding considerably reduces product deformation in cross-section section by 30—50 %. At a choice of modes of cutting it is necessary to consider that force of cutting considerably influences an error of abrasive processing of long details.
