Description
Изобретение относитс к области абразивной обработки и может быть исполь зовано при шлифовании и полировании сет- тических деталей с асферическими поверхност ми .The invention relates to the field of abrasive machining and can be used when grinding and polishing mesh parts with aspherical surfaces.
По авт. св. Кэ 542626 известен способ обработки асферических поверхностей деталей, при котором оси детали и инструмента устанавливают под углом друг к другу и сообщают им вращательное движе ние, а рабочую поверхность инструмента образуют путем вращени образующей заданной асферической поверхности вокруг нормали, проведенной к крайней точкеBy bus. St. Ke 542626 discloses a method for machining aspherical surfaces of parts in which the axes of the part and tool are set at an angle to each other and the rotational motion is communicated to them, and the working surface of the tool is formed by rotating the generator of a given aspherical surface around a normal to
упомш5утой образующей, при этом диаметральное сечение обрабатываемой детали с/1ужит меридиональным сечением рабочей поверхности инструмента по одну сторону от его оси вращени .the mentioned generatrix, with the diametral cross section of the workpiece with the length of the working surface of the tool on one side of its axis of rotation.
Одним из возможных вариантов осуществлени способа вл етс совмещение нормали к крайней точке асферической поверхности с осью вращени инструмента .One possible embodiment of the method is to align the normal to the extreme point of the aspherical surface with the axis of rotation of the tool.
Недостатком данного способа вл етс увеличение погрешности обрабогкк деталей с ростом их крутизны.The disadvantage of this method is an increase in the error of machining of parts with an increase in their steepness.
Цель изобретени - повыщение точности обработки.The purpose of the invention is to increase the processing accuracy.
Дл этого детали сообщают дополнительное качательное движение относительно оси, лежащей в плоскости, перпендикул рной оси вращени детали и проход щей через световой диаметр детали.For this part, an additional swinging movement is reported with respect to an axis lying in a plane, perpendicular to the axis of rotation of the part and passing through the light diameter of the part.
На фиг. 1 представлена схема реализации способа дл пологих деталей (); на фиг. 2 - то же,дл деталей средней крутизны ( S 35 -70°); на фиг. 3 - то обработки крутых деталей ( 75/).FIG. 1 shows the scheme of implementation of the method for flat parts (); in fig. 2 - the same, for details of average steepness (S 35 -70 °); in fig. 3 - then machining steep parts (75 /).
Вращающийс инструмент 1 укрепл ост на вертикальном шпинделе 2, вращающук с деталь 3 - на поворотном шпинделе 4, а угол oL между их ос ми вы чcл ют по формуле:The rotating tool 1 is fixed on the vertical spindle 2, the rotator with part 3 is mounted on the rotary spindle 4, and the angle oL between their axes is calculated by the formula:
d 40°- d 40 ° -
где If - угол между касательными к поверхности издели при его вершине иwhere If is the angle between the tangents to the surface of the product at its top and
на краю;on the edge;
