The material of resin-bond gear hones becomes deformed during operation. The gear hone tooth deformation value depends on the contact point position along the tooth height; it increases by ten folds from the lower point to the top. The deformation values are comparable with metal removal volume and the initial error values of the machined parts. Besides, the kinematic parameters of engagement vary, the values of specific sliding and contact pattern areas are distributed along the part teeth height more uniformly. This should affect the nature and the correction values of gear errors after machining. Experiments proved that accuracy of gears after machining by hones depends on the initial accuracy degree of gears and hones, the paired relationship of geared contacts, the value and nature of distribution of the gear-teeth initial error, machining time. Errors can be intentionally rectified by using gear hones with various elasticity degrees depending on the initial accuracy of parts.
