Investigation and Analysis of Chatter Vibration in Centerless Bar Turning Machine
Chatter vibrations are present in almost all cutting operations and they are the major obstacles in achieving desired surface finish. Chatter vibrations are the self excited vibrations, which has an adverse effect on surface roughness, dimensional accuracy of the machined components. This paper investigates the occurrence of regenerative chatter vibrations in centerless bar turning operation. T...
متن کاملSelf-Excited Vibration in Hydraulic Ball Check Valve
This paper describes an experimental, theoretical model and numerical study of concentrated vortex flow past a sphere in a hydraulic check valve. The phenomenon of the rotation of the ball around the axis of the device through which liquid flows has been found. That is, due to the rotation of the sphere in the check valve vibration is caused. We observe the rotation of the sphere around the lon...
متن کاملApplication of Spindle Speed Variation for Chatter Suppression in Turning
In the present paper the chatter instability of variable speed machining is studied. Though, there exist numerical methods for the computation of the stability lobes for variable speed machining, especially in turning processes the potential of an active spindle speed variation for chatter suppression is mostly unexploited. In the case of a slowly time-varying spindle speed, which is practicabl...
متن کاملMulti-dimensional Modelling of Chatter Stability in Parallel Turning Operation
Recently, use of parallel turning operations has been increasing due to the potential they offer for improved material removal rate using multiple cutting tools. However, chatter vibrations resulting from process instability may limit the productivity in these operations. In order to determine favourable conditions for increased stability, dynamics of parallel turning operations must be modelle...

اهمیت این پژوهش در آن بود که به گفت? بسیاری از پژوهشگرانِ حوز? بازبینی ترجمه، ادبیات موجود در این زمینه به لحاظ نظری و عملی چندان قوی نیست و بخش های موجود نیز برداشت مناسبی از این مرحل? فرایند ترجمه ندارند، اگرچه اخیراً توجه به آن به صورت نظام مند افزایش یافته است. در عین حال، پژوهش های موجود از یک سو بر دگربازبینی بیشتر از خودبازبینی تأکید دارند و از دیگر سو تنها به لحاظ نظری به این موضوع می پرد...
