Формула изобретенияClaim Способ абразивной обработки отверстия инструментом с радиально подвижными абразивными брусками, согласно которому детали и инструменты сообщают вращение и относительное осевое перемещение, а каждый брусок прижимают к обрабатываемой поверхности с силой, плавно изменяющейся при вращении инструмента на начальной стадии обработки и постоянной на завершающей стадии, отличающийся тем, что, с целью повышения качества обработки, изменение силы прижима создают смещением оси вращения инструмента относительно оси вращения детали на величину г^е с — жесткость, характеризующая новку брусков;A method of abrasive machining a hole with a tool with radially movable abrasive bars, according to which the parts and tools report rotation and relative axial movement, and each bar is pressed against the surface to be machined with a force that changes smoothly when the tool rotates at the initial processing stage and is constant at the final stage, characterized in that, in order to improve the quality of processing, a change in the clamping force is created by shifting the axis of rotation of the tool relative to the axis of rotation of the part by ^ E with - rigidity, which characterizes posing the bars; —угловая скорость инструмента; t — время;—Angular velocity of the tool; t is the time; е — эксцентриситет.e - eccentricity. уста- где d — диаметр обрабатываемого отверстия, а на завершающей стадии обработки вра-where d is the diameter of the hole being machined, and at the final stage of processing,
