Description

Изобретение относитс к радиотехнической промышленности, в частности к технике декоративной обработки деталей внешнего оформлени радиоаппаратуры и может быть использовано в приборостроении, промышленности средств св зи, в машиностроительной , часовой промышленности и в других отрасл х техники и быта.The invention relates to the radio industry, in particular, to the technique of decorative processing of parts for external design of radio equipment and can be used in the instrument-making industry, the communications industry, in the machine-building, watch-making industry and in other branches of equipment and life.

Известны способы обработки граненых поверхностей врашаюш,ейс ипстру.ментальной головкой, ось которой располагают под углом к оси врашени заготовки, а соотношение угловых скоростей головки и заготовки выбирают равным целому числу I.There are known methods for processing faceted surfaces of a vrashayush, a structural head with its axis, the axis of which is arranged at an angle to the axis of the blank of the workpiece, and the ratio of the angular velocities of the head and the workpiece is chosen to be an integer I.

Однако этот способ не обеспечивает обработки ступенчатых граней с переменным шаго.м.However, this method does not provide processing step edges with variable shag.m.

Цель изобретени - обработка ступенчатых граней с переменным шагом.The purpose of the invention is the processing of step edges with variable pitch.

Дл этого заготовке сообшают вовзратно-поступательное перемеш,ение вдоль ее оси, а отношение скорости врашени заготовки к скорости ее возвратно-поступательного перемеп 1ени выбирают равным 0,5-3,5 при врезании головки и 10-50 при обратно.м ходе.For this, the workpiece is reciprocated, along its axis, and the ratio of the speed of the workpiece vs to the speed of its reciprocating shift is chosen to be 0.5–3.5 when the head is inserted and 10–50 at the backward stroke.

Рассто ние между резцами выбирают больше шага обрабатываемых грапей.The distance between the incisors is chosen more than the pitch of the processed grapes.

Инструмептальную головку I устанавливают под углом а к оси врашени обрабатываемой детали 2. Соотношение угловых скоростей Vi и Vj головки выбирают равным целому числу. Деталь вращают с посто нным числом п оборотов.The tool head I is set at an angle and to the axis of the turn of the workpiece 2. The ratio of the angular velocities Vi and Vj of the head is chosen to be an integer. The part is rotated at a constant number of revolutions.

Claims

When machining with one diamond cutter, faceted steps form on the surface of the part, the pitch of the formed faces is different; HI, H2, Hj, and when machining with a head with several incisors niar, the faces Hz and Hz, respectively, will be smaller with a constant step HI of steps. The ratio of the speed of lying of the workpiece and the speed of its return-deduction movement S is chosen to be 0.5–3.5 when the tool is embedded and 10–50 when processing, based on the value of the differential of formed stuiene, the allowance removed, and the cutting forces acting on the tool. FIG. 3 shows a diagram of the formation of faceted steps depending on the ratio of h -. Since pe r const, at large values of the Zeag, the part almost instantaneously moves and forms level 3. The steeper the level, the greater the load on the tool, and since the cutting edge is very sensitive to dynamic loads, it goes out of order. In the chosen; - limits: 0.5 .... 3.5 and 10 ... 50 load on the cutting cutter of the cutter does not exceed the established norms. In addition, the faces on the steps x 3 and 4 with - | vJ 0.5-3.5 and 10-50 form a different step. RojioisKa instrumental tools with diamond cutters 5 and 6, a) is placed at a distance of one distance from one fuser. rotating with the speed Vi, it forms faces on different surfaces of the workpiece 2, which simultaneously rotates with the speed Vi and reciprocating movement S. In the interaction of the belt 5 with the surface of the workpiece 2, which moves on rezep with back speed V4, form. Grapings of one tag are formed and underneath .. a distinct slope of inclination, for example, 1-B, after which the workpiece is set to reverse travel with; at a much higher speed, without stopping the milling process. At this moment, the cutter 6 also begins to form faces on another surface, and the cutter 5 causes, on example, a face on the previous surface, since it is separated from the cutter 5 at a distance, h4 5, larger than the pitch of H4 and only comes to work preceding faces. The invention claims 1. A method for treating faceted surfaces with a rotating tool head, whose axis is arranged at an angle, to the axis of rotation of the workpiece, and the ratio Y | The new speeds of the head and the workpiece are paBtibiM integer, characterized in that, in order to process the stepped 1) facets with variable clamp, the workpiece is reciprocating, e. The naic.ibiioro mix is chosen to be 0.5 --- 3.5 when the heads are incised and 10-50 11) in oGpaiiio.M.
