Description
Изобретение относиге к: области обра ботки цетапей резанием и может быть ис попьзовано при обработке цетапей на наст роенных фрезерных станках и станках с чисповыМ программньЕм управпенкем. Известен способ компенсации погрешностей обработки на станках с.ЧПУ, за пючающийс в том, что коррекци внос г- с путем начального смещени фрезы на величину поправки RlJ . Такой способ трудоемок, и кроме того , Ив применим прп обработке замкну1о го контура.

Использование предлагаемого спосх ба компенсаци погрешностей обрабогка позвол ет приданием дополнитепьвого ащени фрезе вокруг оси, смещенной относитепьно оси фрезы, вносить поправку в настч роечный диамегр фрезы на величину, ра.The invention is attributed to: the area of machining of tsetapey by cutting and can be used when treating tsetapey on customized milling machines and machines with numerical software control. There is a known method for compensating machining errors on machines of the CNC system, which is due to the fact that the correction is introduced by d-c by the initial displacement of the milling cutter by the amount of the correction RlJ. Such a method is laborious, and in addition, Iv is applicable to the processing of a closed loop. The chain of contraction and the increase of the copula has been introduced into the process of working. The method is illustrated by the scheme. . In the drawing, the following notation is given: 1 machined tsep} 2 - mill; O - axis Fre; m 1; O is the axis of digital rotation of the cutter; D - tsamamvgrfrWhen the cutter rotates at a speed of Wf around its own axis O, the allowance t is removed on the processed cetapies, size B is obtained at the cetapas. around the axis of O., mixed with respect to the axis O and ia, the detail of irv-start 4 is shown in detail; h-D, i.e., the correcting correction is equal to size B, equal to D. Dp ensure uniform, teeth cutter speeds W, in Shd apoj we choose from the ratio W Lj gce 1f - the number of teeth of the cutter. Using the proposed method of error compensation, processing allows, by adding a mill to an additional axis around an axis shifted relative to the axis of the mill, to make a correction to the adjustment of the mill cutter by the value of, pa.

This will compensate for both the dimensional wear of the cutter and the deformation of the AIDS system without entering the design into the machining program. This creates a new approach to the creation of a library of software and ways to reduce the range of tools used.
