Description

и в прототипе, т.е. сравнивэот количество сегментов стружки с собственно частотой .высокочастотных колебаний и по наибольшей кратности совпадени  определ ют резонирующий элемент.иand in the prototype, i.e. comparing the number of chip segments with the actual frequency of the high-frequency oscillations and the greatest resonance multiplier determine the resonating element. and

Основанием дл  приравнивани  количества сегментов стружки к частоте высокочастотных колебаний  вл етс  то, что периодический характер процесба резани   вл етс  источником внутренних колебаний в зоне резани , а также положений сдвиговых плоскостей . Другими словами, и количество сегментов стружки и частота высокочастотных колебаний определ ютс  в своей основе одним и тем же источником - образованием сдвиговых плоскостей . -Такое положение и  вл етс  причиной дл  равенства количества сегментов стружки, образовавшихс  ,в единицу времени, частоте высокочастотных колебаний.The reason for equating the number of chip segments to the frequency of high-frequency oscillations is that the periodic nature of the cutting process is a source of internal oscillations in the cutting zone, as well as the positions of the shear planes. In other words, both the number of chip segments and the frequency of high-frequency oscillations are determined basically by the same source — the formation of shear planes. The position is the reason for the equality of the number of chip segments formed, per unit time, to the frequency of the high frequency vibrations.

Способ был апробирован в производственных услови х.The method was tested under production conditions.

Дл  проверки достоверности результатов , определение наход щегос  в резонансе элемента систе1«л СПИД произ ,ведено двум  способами: использованием частоты высокочастотных колебаний, измеренной с помощью высокочастотного частотометра, и с использованием количества подсчитанных сегментов е стружки, образовавшихс  в единицу времени.To check the reliability of the results, the determination of the system element in the resonance was made in two ways: using the frequency of the high-frequency oscillations measured with the high-frequency frequency meter and using the number of counted chips e formed per unit time.

Эксперименты проводились на станке мод. 165, Обрабатываемый материалсталь 45, прокат 0 100мм, 6 г 1270мм. Данные экспериментов сведены в таблицу 1. Дл  обрабатываемого материалалатуни /ф 82мм и 61016мм/, данные сведены в таблицу 2.The experiments were carried out on the machine mod. 165, Machined material steel 45, rolled steel 0 100mm, 6 g 1270mm. The experimental data are summarized in Table 1. For the material being processed, the plates / F 82mm and 61016mm /, the data are summarized in Table 2.

Некоторое различие между измеренной частотой высокочастотных колебаний и количеством obisasoBaBnraxcH сегментов стружки в единицу времени Объ сн етс  неточностью проводимых измерений с помощью частотометра. Однако, совпадение частот  вл етс  вполне удовлетворительным. При этом, частота образовани  элементов стружки более точно отражает истину, так как не подвержена вли нию неточностей измерительных приборов.Some difference between the measured frequency of high-frequency oscillations and the number of obisasoBaBnraxcH chip segments per unit of time. This is indicated by the inaccuracy of the measurements made using a frequency meter. However, the coincidence of frequencies is quite satisfactory. At the same time, the frequency of formation of chip elements more accurately reflects the truth, since it is not affected by inaccuracies of measuring instruments.
