الاهتزازات القسرية للنظام التكنولوجي في عمليات الخراطة الطولية للأعمدة باستخدام مجاري تكسير الرايش

الملخص EN

This research studies the forced vibration which is generated during the internal turning cylinders by using chip-Breaking flutes.

These flutes are spiral with big pitch formed on the surface of the working- piece for breaking the chip to small pieces that can be easily moved away from the cutting place.

These flutes periodically cause a change in the section of the cutting layer which cause a creation of the forced vibration motion, it has been found the differential equations that represent the motion of the system and studying the characteristics of "amplitude-frequency" and the effects of cutting depth, feeding, cutting speed and the depth of the flute on them.

As a result it has been found a stability field for the studied motion of the technological system in which the amplitude of the generated vibration is nearly constant and it has a small effect on the accuracy of the working pieces.
