Description

Изобретение относитс к способам обработки металлов резанием и может быть использовано при обработке деталей на станках с программным управлением.The invention relates to methods for metal cutting and can be used in the processing of parts on machine tools with software control.

Известен способ дроблени стружки, заключающийс в нанесении стружкораз- делительных канавок на черновом проходе обрабатывающим резцом, совершающим радиальные врезани Т . Однако этот способ имеет ограниченное примененThere is a known method of crushing chips, which consists in applying chip separation grooves on the roughing pass with a cutting tool that performs radial incisions of T. However, this method has limited application.

Цель изобретени - расширение технологических возможностей способа за счет обеспечени стабильного дроблени стружки на всех рабочих проходах, включа черновые.The purpose of the invention is to expand the technological capabilities of the method by ensuring stable chip fragmentation on all working passages, including draft.

Это достигаетс тем, что в способе, заключающемс в том, что детали сообщают вращательное движение, а инстру- менту-перемещение вдоль детали по прорамме с последним чистовым проходом, инструменту сообщают перемещение с постепенным врезанием в припуск последующего прохода, за исключением последнего прохода, с периодическим отводомThis is achieved by the fact that in the way that the parts impart a rotational movement, and the tool-movement along the part along the program with the last finishing pass, the tool is reported to move with a gradual incision into the allowance of the subsequent pass, with the exception of the last pass, with periodic tap

инструмента в направлении, перпендикул рном к обрабатываемой поверхности на величину врезани , причем величину периода между отводами выбирают в зависимости от приемлимой длины перерезаемой стружки, а врем отвода не меньше времени одного оборота детали.of the tool in the direction perpendicular to the surface to be machined by the amount of penetration, the period between the taps being chosen depending on the acceptable length of the chips being cut, and the time of withdrawal is not less than the time of one revolution of the part.

На чертеже показана схема, иллюстрирующа предлагаемый способ дроблени стружки.The drawing shows a diagram illustrating the proposed chip crushing method.

Claims

The vertex moves along a 1-2-3-4-5 path. . . 24, i.e., the tool periodically makes a longitudinal movement with a gradual plunging into the allowance of the subsequent passage in sections 1-2, 3-4, 5-6, etc., and in sections 2-3, 4-5, 6- 7, etc., the tool is retracted in the transverse direction by the amount of penetration in a time that is not less than the time of one revolution of the part. Due to this removal, chips are cut, and the length of sections 1-2, 3-4 is taken depending on the length of the cut chips. With the latter, j3iif..f. Aim of the finishing pass, when epoaanvie in the stock, or rather in the part, is unacceptable, checkpoint; -r | rt; 1O-, ptg R3-OQ previous incisions tool. The invention The method of crushing, breaking down, which consists in the fact that the details communicate the rotational movement, and the tool - move along the part according to the program with the last finishing pass, about the fact that, with the aim of both the liver stable crushing chips on the finishing and roughing aisles, the tool .J4 is reported to the tool and, with a permanent incision into the allowance of the passage, for the claim / by the last passage, with periodic removal of the tool in the direction perpendicular to the surface to be machined by the amount embedded , The magnitude of the period between the taps is selected depending on an acceptable length being cut chips and discharge time is at least one time items turnover.
