Изобретение относитс к техно , логии обработки резанием и может быть использовано при обработке угловых внутренних канавЪк в отверсти х деталей .The invention relates to techno logging and can be used when machining angular internal grooves in the holes of parts.

По основному авт. св. № 642082 известен способ точени внутренних поверхностей, по которому оправку, несущую резец, устанавливают под углом к оси отверсти обрабатьгааемой детали, равным углу наклона образу щей протачиваемой угловой канавки к торцовой плоскости детали, и осуществл ют поворот резца по круговой траектории со скоростью подачи при одновременном сообщении вращени детали вокруг оси обрабатьшаемого отверсти со скоростью резани ij,.According to the main author. St. No. 642082 discloses a method of turning internal surfaces, according to which the mandrel carrying the cutter is set at an angle to the axis of the machining hole, equal to the angle of inclination of the angular groove to the end plane of the part that is being machined, and the tool rotates along a circular path with a feed rate while the message of rotation of the part around the axis of the hole being machined at a cutting speed ij ,.

Цель изобретени - повышение точности профил протачиваемых внутренних ,углов Х канавок.The purpose of the invention is to improve the accuracy of the profile of the internal grooves, the angles of the X grooves.

Дл зтого резцу в процессе обра ботки сообщают дополнительное перемещение параллельно оси его поворота, равное по величине и противоположное по направлению искажению образующей 66ковой поверхности канавки.For the cutter, during machining, an additional displacement parallel to its axis of rotation is reported, which is equal in magnitude and opposite in the direction of distortion of the generatrix of the surface of the groove.

Способ иллюстрируетс чертежом, где -на фиг, 1 показан осевой разрез обрабатываемой детали и положение инструмента; на фиг. 2 - вид по стрелке А на фиг, 1.The method is illustrated in the drawing, where FIG. 1 shows an axial section of the workpiece and the position of the tool; in fig. 2 is a view along arrow A in FIG. 1.

Оправку 1, несущую резец 2, устанавливают под к оси отверсти обрабатываемой детали 3, равным углу наклона образунщей протачиваемой угловой канавки 4 к торцовой плоскости детали 3.The mandrel 1, the carrier cutter 2, is set under the axis of the hole of the workpiece 3, equal to the angle of inclination of the corner angle groove 4 to the end plane of the part 3.

Claims

Details 3 report the rotation about the tool axis around the machined hole at cutting speed, the mandrel 1 carrying the cutter 2 turning around its axis at the feed speed and simultaneously moving along the axis of rotation by an amount necessary to compensate for the error in shaping the profile of the angled groove formed 3. -8 as a result of feeding the tool along a circular path. . As a result of the addition of the movements of the cutter 2 from movement along a circular path and a straight-line corrective movement along the axis of the mandrel, an angular groove is formed with the straight-line generators. The method improves the condition of the cutter. And improves the accuracy of the machining. The invention of the method of turning the inner surfaces, according to ed. St. No. 642082, about the fact that, in order to increase the accuracy of the profile of the internal corner grooves, the cutter during processing is reported to have additional displacement parallel to its axis of rotation, equal in magnitude and opposite in the direction of the distortion of the lateral surface forming the groove.
